Buying Guide for the best heavy duty hammer drill

In the following space, you will find a guide to buying the best stick, which has the purpose of instructing you with some of the most important features so that you can select an economical and excellent quality product.

Shopping guide

Power and strength

Before checking how much a hammer costs, we recommend that you take into account the potential and advantages that it presents. Also, in this comparison of hammers, you will find some mechanical and other electric models, so we recommend that you verify the use that you intend to give so that you select one that meets your expectations.

The electric hammers in this list have power and strength, but these are identified with watts (W), Joule (J) and Newton meter (Nm); different powers and forces that use this equipment to provide various types of finishes, whether to drill, hit, chisel or demolish, so that the more numbers are with the unit of measure of force or power that we mentioned in the beginning, these They can carry out their work without any inconvenience.

Also, you have to evaluate if the work you are going to do is easy or complicated, so if you are only going to work the wood, a power level of 700w or 20 J will be enough to drill. Still, if you have among your plans to drill concrete or concrete, you will need these numbers to be at least 1400. In addition to this, the same applies to asphalt work, so you will require that the jackhammer has enough power in Nm to be able to drill the surface without It gets stuck in the process.


Another essential feature that we recommend you review is the manufacturing materials.

If the hammer you intend to acquire is made of wood, the handle has to be durable and resistant, such as Maya or cedar, so that it can withstand impact and vibrations. The head should be made of steel, if possible, stainless, which will provide high resistance to rust and corrosion.

But, if it is an electric hammer, it evaluates that its structure is of a resistant plastic so that you avoid electric shocks and ruptures. Still, if its surface is metallic with nylon or plastic, it will prevent that a high voltage can affect you, at the same time that this withstands the impacts and vibrations of pounding.


The electric hammers, in their majority, have several services, which will provide them with versatility so that you can use them for different tasks. Also, some models have varying levels of strength, power, and speed. That is, they will allow you to adjust it to drill or hit surfaces and structures and thus reduce the time it would take to use standard hammers that cannot level speed, strength, or power.

On the other hand, some hammers have the function of changing the bits with ease and blocking them. A handy feature to remove one tip, place another, and secure it to avoid accidents.

Therefore, we recommend that the model you select has two or more additional functions and adjustable speed, power, and force levels so that you get the most out of your hammer.

Weight, dimensions, and ergonomics

This feature will depend on the type of hammer and the use you intend to give it. That is, if you need one that you can take anywhere, the product has to have a lightweight and comfortable dimensions so that it can fit in your pockets, in case of manual hammers or a carrying case for electric models. Additionally, the weight and sizes in the latter have to go according to what you can bear, since you will not be able to manipulate large equipment or that has a high weight if your structure is thin and you are not accustomed to this type of work.

When making use of a hammer, it is necessary that this can provide comfort, so you have to look at its handle and handle it. This has to be padded so that you do not hurt your hands and reduce the levels of vibrations when hammering, which will prevent fatigue and headaches.

Therefore, we recommend that you evaluate what type of work you frequently do so that you select a hammer that has dimensions and a weight accordingly so that you can use it comfortably.

Heads and accessories

In mechanical hammers, manual or better known as classic hammers, the head is of the utmost importance, since it has to be strong enough to withstand the impacts you give to objects.

Also, some models have magnetized designs, which will help metal objects such as nails to cling very quickly, preventing you from using your hands to avoid accidents.

On the other hand, electric hammers also have heads, but these are commonly known as drill bits, since their tip can be exchanged with a different one, whether it has been broken or worn or you simply need to drill, hammer, destroy, polish, etc.

In addition to this, you also have to look at how many units come and if it includes gloves and tools so you can give preventive maintenance to the equipment.

Therefore, we recommend that among your options, you select a model that has a unique design, has reinforcements in the impact zones, which will provide a longer lifespan and the bits you need to use for your activities.

Frequently asked questions

Q1: What is the ball hammer for?

These products are mostly used in mechanics, blacksmithing, and locksmith to perform different types of finishes. This is because it has a circular end to rivet the metal and its other side to crush.

Q2: How to use an electric hammer?

First, we recommend that you have the right protective tools (glasses, masks, and gloves). Then, plug the equipment into an outlet near the area where you are going to work so that you avoid breaking the cable or disconnecting it if you get to move.

Next step, take the hammer with both hands so that it does not move, and you can have a higher level of security. Also, if you are going to work in concrete, asphalt, or wood, we recommend that you change the bit or tip to the corresponding one for that type of work. Turn on the equipment and, if you can regulate the speed or power, do it, but starting from the lowest level and increase if the surface does not break or pierce.

When you finish using the electric hammer, we recommend that you wait a few minutes for the drill to cool because if you touch it instantly, you could burn your hands.

Q4: What kind of lever is a hammer?

The hammer is a lever of third grade or gender when used to hit since the wrist is used as a support point, and the wood or surface to be drilled would be the load that opposes it.

Additionally, this is also a first grade or gender lever when used to remove nails. That is, the force generated by the user is gradually increasing to perform that function, and the load is the resistance that the pin presents for it.

Therefore, a hammer is a first and third-degree lever depending on its use.

Q5: What is a hammer made of?

For the most part, the hammer is made of steel in the head and wood in the body, which favors ergonomics, but there are models, depending on its use, which is made entirely of steel, iron, nylon, plastic or wood.

All You Should Know About A cordless drill

What is a cordless drill?

A cordless drill is a tool that you can use to screw and drill. The device is powered by a battery motor and is similar to a drill . The battery allows you to carry out the screwing and drilling without cables, so a power connection is not required. This network-independent work helps in many cases and makes the cordless screwdriver particularly popular tools, even in a household without hobbyists.

In most cases, the cordless drills have a slip clutch . This ensures decoupling between the drive and the work spindle when the preset maximum torque is reached. This leads to the characteristic turning of the spindle. With the slip clutch, even screwing is possible without the material being overloaded. Some of the cordless screwdrivers are equipped with an adjustable depth stop with which countersunk screws can be brought to the correct height so that they are flush with the surface.

The newer cordless tools support network-independent DIY and rely on the powerful lithium-ion batteries. In addition, the motors of these devices are further improved, which affects the good performance of the cordless drill. So these tools can now keep up with the cable devices.

Basically, the cordless drill is used for screwing in and unscrewing screws. It is equipped with an effective gear ratio that works on the one hand at a low speed and on the other hand enables a relatively high torque . This makes screwing work easier for users. Some cordless screwdrivers are not provided with a drill chuck, they have a bit holder.

How does a cordless drill work?

Compared to drill who cordless drill a smaller speed. They are equipped with a coupling that makes it possible to set the decoupling from the work spindle. With this function, the torque can be prepared for the upcoming work so that the screws cannot be overtightened.

The cordless drills are activated via the control currents, which are sent to the control electronics via the guide cable immediately after the on switch is pressed . The direction of rotation, the control of the torque and the motor rotation are regulated via the control electronics. The battery cells ensure that the energy produced from them is fed to the engine .

Since the cordless drill is not only used for screwing, but also for drilling in wood , light building materials or even metal , it needs sufficient performance. In addition, a drill chuck must be available so that the necessary drill can be used. Many devices have two gears, so you can use a high torque at a low speed , which makes sense when screwing, but can also set a high speed for drilling . The gear shift supports an uncomplicated change from first gear with the high torqueto second gear at high speed. Powerful or fast, different settings are required for different projects .

The cordless drills often offer additional presettings for certain fine work . This means that precise torque preselection can be used at the front of the tool head to immediately sink the screws deep into the building material. The speed can also be influenced via a speed control . This extra function ensures a direct reaction : If you press the trigger switch firmly, the screwdriver turns faster.

The function of the battery has been improved in recent years. Most of the cordless drills from the test comparison are now equipped with lithium-ion batteries. Compared to the older nickel-cadmium batteries, these are safer on the one hand, and on the other hand there can be no impairment due to unfavorable charging intervals with the newer batteries.

Depending on whether you are drilling or screwing with the cordless drill, various drilling and screwing inserts are available. Bits are also mentioned here. The inserts are fixed on the head of the device: the drill chuck or bit holder is located here . You choose the right insert and choose between different diameters , lengths and degrees of hardness. In some cases there are also differences in shape. This shows whether the inserts are suitable for softer materials such as wood, for lightweight walls or for harder building materials such as masonry.

After inserting the bits, the actual function of the cordless drill begins, which turns to the right as standard: This allows the drill holes to be made and screws to be screwed in? You can change the direction of most of the modern cordless drills from the test comparison . The right-left-race helps to handle the machine better, he also allows the unscrewing of screws .

Advantages & application areas

The cordless drills are used for all kinds of work. Whether you just want to hang up a picture, assemble furniture or repair something: A practical cordless tool is indispensable even for the layperson in such cases. The cordless screwdriver is part of the standard equipment for do-it- yourselfers , but even if you only have a small tool box, you should buy the useful and versatile device. If you make sure that the battery is always charged, the tool is suitable for larger projects and for small jobs and is always ready for use. Thanks to the bit holder or the drill chuck, the attachments can be easily replaced and quick repairs madeperform in no time. With the cordless drill, the screws are screwed in or loosened more easily than when working with a simple screwdriver. In addition, the cordless tool is easy to use and weighs less than the large drill .

Because the battery can be inserted with one hand , the device does not need long preparation. In addition, you do not have to look for the nearest socket, but can use the cordless drill flexibly, whether you tighten a screw on the vehicle or fix something in the garden shed. The cordless drill can be safely stored and easily transported in the original tool case. Often there is a box or a shelf for the bits or drills in the accompanying case . So these small parts are not lost and you can quickly find the right size.

Compared to the professional drill drivers that work with electricity, the cordless drill drivers are not as powerful. In addition, the weight is not much less due to the battery. But the cordless drills offer more flexibility. However, you should make sure that these cordless tools are not suitable for all building materials. If you are primarily looking for a device for screwing and only for light drilling work, the cordless drill from the 2020 test is the perfect tool . The mini models are particularly handy and work with bits. This makes them indispensable helpers when assembling furniture.

Thanks to the precise shape of the bits belonging to the cordless drill, it is possible to find the right size to match the screws. High quality and material strength ensure that neither the inserts nor the screws round out. This makes it easy to loosen and fasten the screw connections repeatedly, without there being weaknesses in the power transmission and without the screw heads becoming worn.

What types of cordless drills are there?

The terms cordless drill , cordless screwdriver and cordless drill driver are usually interchangeable. However, the term cordless screwdriver is mainly used for the relatively small tools that are only suitable for screwing and less for drilling.

The mini screwdrivers are a sub-form of the cordless screwdriver, so to speak, and stand out due to their small size. These small devices can be used to tighten or unscrew screws. Compared to the larger standard cordless drills , the mini screwdrivers are very lightweight. Their compact design qualifies them primarily for furniture construction. The mini screwdriver has a bit holder, which makes it possible to use different screw attachments. Ideally, the bit holder is magnetic so that the attachments hold securely.

The standard models of cordless drills are suitable not only for screwing but also for drilling. However, there are certain limits due to the lower performance compared to impact drills.

The smaller cordless drills from the test often have the shape of a pen and are suitable for easier assembly work. In contrast, the classic cordless drill / drivers are equipped with a T-handle. In the older models, the pistol grip is often found, which is reminiscent of the drill.

Depending on the quality standard, the cordless drills can be equipped with an additional spotlight. This mini spotlight helps to find the screw or the mark for the hole in difficult lighting conditions.

The cordless drills , which correspond to today’s level of innovation, are equipped with Li-ion batteries. However, NiCd or NiMH batteries are often still found in the older devices. Some of the latter are also available for cheap, more recent tools. Compared to NiCd batteries, modern batteries are not only significantly lighter, but also more powerful. The NiCd cells offer approximately twice the energy density compared to the NiCd batteries, and the Li-Ion batteries double the value of the Ni-Cd cells again. The Li-ion batteries also impress with their short charging time and extremely low self-discharge.

The advantages of the cordless drill mentioned here mainly relate to the comparison to other tools:

  • Ideal for mobile screwdriving and drilling work due to current-independent function,
  • light weight,
  • compact format,
  • ease of use,
  • relatively low speeds and therefore also suitable for fine work,
  • cheap price.

The disadvantages of the cordless drill:

  • The battery must be charged again and again,
  • relatively low force.

This is how the cordless drills are tested

The cordless drill test is about the flexibility of these devices, their quality characteristics and their suitability. If you like tinkering, you can’t do without this cordless tool. The cordless drill driver helps with small and precise work as well as with difficult projects. The battery must have the necessary capacity so that you are not really dependent on a power connection. So there is no need to take a break when the battery is weak. But it’s not just the performance of the battery that counts. The other product types also have an impact on the purchase decision. The test carried out here is intended to inform interested readers about what is important in the selection and which features characterize the quality and the possible uses of the cordless drill .

The basic equipment usually offers little orientation, because not only the test winners of the cordless drills are supplied with a carrying case and other accessories. It is more important to check the parameters of the cordless drill. This includes torque, speed, battery capacity and other operating data, which are listed in detail in the following points. The particularly relevant criteria include the operating voltage and the capacity. However, the quality of the materials and workmanship must also be checked, as well as the ergonomic design and the services offered by the manufacturer.

The power in watts

If you are looking for a powerful cordless drill , you first pay attention to the performance. For most devices, this is at least 500 watts and can go up to 1,500 watts depending on the manufacturer and model. With increasing wattage, the device is also suitable for harder materials. However, with most cordless drills, a maximum output of 700 watts is sufficient to carry out normal drilling work and to drill into soft materials such as wood or plaster.

The battery voltage

The cordless drill drivers are available in various performance classes. The power of the tool can be recognized from the voltage of the battery. Typically this is between 10.8 and 18 volts. The standard models often have 14.4 volts. The mini screwdrivers , which work with 3.7 or 7.4 volts, are suitable for fine work.

If the number of volts increases, it should be borne in mind that this increases the power but also increases the power consumption. The battery drains accordingly quickly. Therefore, you should not only pay attention to the performance, but also check the other data such as the torque.

The torque

The torque shows how high the power of the cordless drill is actually. As the torque increases, the device becomes stronger and stronger. The unit for the torque is Newton meters, abbreviated Nm. This value refers to the speed of rotation of the screwdriver. A high torque helps to screw the screw connections into solid materials, while a weaker cordless screwdriver with low torque does not provide the necessary power here. Torque , battery voltage and idle speed are crucial for the performance of the cordless drill.

The idle speed

The speed at which the screwdriver rotates can be seen from the idling speed. For simple cordless screwdrivers, this value is around 600 rpm, while the more powerful test winners for cordless drills manage up to 1,300 rpm. The better cordless drills can be switched in two gears and allow the speed to be set variably. For certain jobs, you should choose a rather low speed, for example to prevent the processed wood from splintering.

The torque setting

With many cordless drills , the setting can also be changed for torque. This ensures that the drill screw slips at a certain point in the power transmission.

This makes it easy to do repetitive work. If you screw in a lot of screws made of the same material into the same building material, setting the torque saves you from having to constantly check, because here all the screws are finally firmly seated in the plasterboard. However, this setting function is not available on the inexpensive devices. Particularly powerful cordless drills that work without torque adjustment can “wear out” a screw or they can slip out of your hand more easily.

Therefore, you should make sure that the selected tool has the function and use it. This prevents excessive wear on the material and protects against possible accidents.

The setting of the direction of rotation

The direction of rotation can be changed on many cordless drills . A lever switch is usually available for this. When this switch is flipped, the direction of rotation changes so that you can not only turn the screws clockwise, but also loosen them by turning them to the left. Changing the direction of rotation can also be useful if the tool jams and you want to loosen it again.

The aisles

The cordless drills , which are used not only for drilling but also for screwdriving, should be equipped with two gears. If there is only one gear, the speed for drilling is not sufficient, and there is only a limited force when screwing. Most cordless drill drivers from the test have two gears and are therefore versatile and powerful helpers.

The weight

Depending on their performance and design, most cordless drills weigh between 1000 and 1500 grams. If you do a lot of do-it-yourself work and also work overhead, you want a device that is as light as possible but still shows no weaknesses in performance. In other cases, it may make sense to choose a cordless drill with a slightly higher weight that has a higher torque for this.

The drill chuck

The drill chuck is the holder on the head of the tool. The drills are attached here. The simple drill chucks are opened and closed with a special key, but many cordless drills from the test have a quick-release system or an SDS drill chuck. This saves you the key because you only have to turn the front component to insert and remove the drill.

The smaller cordless drills have a simple holder for drill bits, which are also known as bits. A magnetic holder is often used here so that the bits cannot be lost. The numerous formats of the drills and bits can be adapted to the different building materials and the screws.

The battery

Today’s cordless drills from the 2020 test primarily work with lithium-ion batteries. These batteries remain unaffected by the charging intervals, while the outdated nickel-cadmium batteries can be damaged.

The batteries should have a good capacity, which is given in ampere hours (Ah) and must be considered in relation to the battery voltage. A battery with 14.4 volts and 2.4 Ah therefore lasts twice as long as a battery with the same voltage and 1.2 Ah. The battery capacity affects the weight, so you need more muscle power for a longer shelf life. A small battery is generally sufficient for only rare screwdriving work, but if you use your cordless drill more often in continuous use, the capacity should be larger.

In the test of the cordless drill , it was found that even the small batteries have a fairly good durability. If you have a second battery, you can charge it while working with your cordless drill. This enables the batteries to be replaced quickly.

The long-life batteries are ideal for working outdoors when you don’t have a power source nearby. A second battery can also be worthwhile here, which you can fill up at the charging station. The lithium-ion batteries have a particularly short charging time, so that a direct change is possible: while the first battery is in the device and gradually discharges at work, the second recharges.

The ergonomics

In addition to the performance data, the ergonomic shape of the cordless drill driver plays an important role. The test winners of the cordless drill impressed by the intelligent shape, which has a secure grip. The controls are easily accessible here, and you can also work with the somewhat smaller devices in difficult corners. Among the favorites for cordless tools are the models with a T-handle. This offers an optimal hold and is mostly equipped with a non-slip material. The traditional devices with pistol grip are easy to grasp. Here, the relationship with the classic drill is unmistakable. The pin shape is often found in the small drills. This is also sufficient for light work.

The smaller, narrower cordless drills are particularly popular with women who like to tinker . These are comfortable to hold and have a pleasant shape. The male handyman also pays attention to the ergonomic design and is pleased with the shape of the handle, which adapts perfectly to the anatomy of the hand.

Other fastenings

Some of the cordless drills from the test comparison are equipped with a holder for bits and a belt clip. Such a clip makes it possible to fix the tool to the work trousers. This is particularly useful if you climb a ladder or want to have your hands free in a particular situation. Sometimes the belt clip can be easily moved to the other side. This change of page is helpful if not only right-handed or left-handed people use the cordless drill.

The security

For the safety of the cordless drill , ergonomics must be taken into account on the one hand, and on the other hand the material should be as robust as possible and not susceptible to a wide variety of influences. The devices are often provided with a rubber coating on the handle and are otherwise designed primarily for stability. A few slight scratches are harmless, but the case should still be able to withstand a lot, especially if you use the cordless drill frequently outdoors .

Another safety feature is the safety clutch. This blocks the power transmission from the device motor to the drill if the cordless drill jams. This interruption protects the user from injuries and reduces the risk of the machined parts being destroyed.

The lighting

Many cordless drills are equipped with LED lighting for working in dark corners. In the meantime, this lighting has almost become standard. The light shines directly to the front so that you cannot overlook the screw or the marking.

The transport case

Most cordless drills arrive in a suitable tool case for storage and transport. This stable tool case provides the device with the right hold so that it does not slide back and forth. The case also protects the cordless drill from dirt and damage. In general, the box is equipped with a continuous suitcase handle, so that even the slightly heavier cordless drill can be carried easily.

The boxes and cases of the big brands are often designed so that they can be stacked on top of each other. This reduces the space required in your own workshop. Some of the transport cases also have an extra box or slots for the drill bits and other small parts. This makes it even easier for users to store their tools and accessories properly.

What should I look out for when buying cordless drills?

If you want to buy a cordless drill, you should know what work you want to do with it. The difference between the mini screwdrivers and the powerful test winners of the cordless drills is very large, so you should definitely think about which materials are mainly processed with them. A standard model is usually sufficient for occasional use, but if drilling in harder materials, the impact drill may be the better choice.

For the inexperienced amateur handyman, who rarely take the cordless drill in hand, a simple device that weighs not much more than 1 kg and has a battery voltage of 1200 V, for example, is sufficient. For the hobby craftsmen and the professionals there are, however, stronger devices that cost more, but are also of a significantly better quality. Particularly precise work may be necessary when screwing: Here, the smaller devices come into question, which are safe to use and can be set precisely.

Unlike power tools that require a power source, the cordless tools work wirelessly. So they offer much more flexibility and are suitable for mobile use. If you are often on the go with your cordless drill , you should make sure that the transport case is robust and has space for the accessories. In addition, the battery must be particularly strong in mobile use.

Women like to use the lighter cordless drill / screwdriver, because their low weight does not lead to fatigue even if the operation takes a little longer. Basically, the larger and heavier cordless drills from the 2020 test are also easy to use in relation to the drill, so that you do not slip off when you attach them. The modern ergonomics also support you during use and reduce the effort.

Depending on the preferred application, you can opt for the smaller devices with 10.8 volts, for the medium battery drills or for the more powerful models with up to 20 volts. The modern technology, the harmonious and ergonomic design as well as the durability and the workmanship quality are important criteria.

As already explained, attention must be paid in detail to the torque and the battery capacity. The general rule of thumb for large construction and assembly projects is: the stronger the performance, the better. However, if you use the cordless drill for repair work on the car or for other projects where a certain torque must not be exceeded, it must be ensured that the screws are not subjected to too much force.

If you are interested in cordless drills, you will find cheap but also expensive products from the manufacturers. When fully equipping your own workshop, it may be worth taking a look at the other tools of the individual brand manufacturers. Some of the batteries can be inserted from one tool to the next if the same battery voltage of 12 or 14.4 volts is used. Replaceable batteries can save money, even if the original devices are initially a little more expensive than the own brands of the hardware stores. You can find out whether the batteries are actually compatible from specialist dealers or directly from the manufacturer.

When deciding on expandable workshop equipment, compatibility should not be neglected. And you should know that a change to another brand is hardly possible. For this, the basic equipment can be gradually increased, whereby you can do without additional batteries if necessary.

Brief information on leading 7 manufacturers

The big brands for cordless drills are mainly traditional companies. These have been established in the field of electrical and cordless devices for many decades. If you have focused on a particular company, you will not only find your preferred cordless drill , but also other tools for household use. Most of the time, it’s not worth buying a cheap no-name product. The renowned brand names are not in such high demand for nothing, and you can also buy original tools from well-known producers at a reasonable price. The following list provides some basic information about some of the most important manufacturers worldwide.


The  Bosch GmbH  is a company founded in 1886 by Robert Bosch multinational German company. It is active as an automotive supplier, manufacturer of consumer goods (power tools, household appliances) and industrial and building technology (security technology) and also in automated packaging technology, where Bosch occupies the leading position. Robert Bosch GmbH and its around 450 subsidiaries and regional companies in around 60 countries make up the  Bosch Group.

Black & Decker

The Black & Decker company  has its origins in 1900. The US company presents a variety of electrical and cordless tools, including accessories. In 2009 the Stanley Works group took over the company. In addition to tools for diy and professionals, Black & Decker also has small household appliances in its range. There are also garden tools and products for the automotive sector.


The Metabowerke GmbH  , headquartered in Baden-Württemberg Nürtingen is a manufacturer of power tools. The company was founded in the 1920s. The name is derived from ” Meta ll bo hrdreher”, a hand drill. Today Metabo offers a wide range of power tools.

The Trotec Group is all about the optimal conditioning of air and water in industry, the leisure sector and in the construction industry: You can buy dehumidifiers, construction dryers, heating devices, air conditioning units, fans, wind machines and air purification systems for a wide range of applications from us rent. We offer you additional services and training.


Festool has existed since the 1920s and initially focused on repair work and conversion work on woodworking machines. The product portfolio changed over time. Festool has been an expert in high-performance power tools for several decades. In the innovations presented by the experts, the company relies on strong feedback from customers and brand friends. This should further optimize the devices. More convenience, a faster result, better precision, these are exactly what users want. For Festool, the focus is on perfection, and the more than 350 patents and numerous awards show how great the company’s innovative strength is.


Hitachi is a Japanese company that is headquartered in Tokyo. It is an international company for electrical engineering and mechanical engineering. From the very beginning, after the company was founded in 1910, the electrical engineering workshop had striven for higher things. The company grew into an important production location. The first successes were the series production of electric motors and the production of industrial plants. Household appliances were added later, and communications, entertainment and information electronics soon followed.

Internet vs. Specialist trade: where is the best place to buy my cordless drill?

Sometimes the discounters or supermarkets offer cheap cordless drills that are convincing in their quality. With cheap goods, however, you have to expect that they have a rather short life. In addition, buyers should keep in mind that there can be difficulties in procuring spare parts. For this reason, it is usually more sensible to buy the cordless drill in the hardware store or in specialist electronics stores. Here you not only get expert advice , but you can buy the necessary accessories or a spare part if necessary.

However, research and shopping on the Internet is even easier. The convenient online search from home makes it unnecessary to search several shops and hardware stores. In addition, the range on the Internet is much more extensive. However, one does not lose the overview, after all there are filters and sorts that help one to compare the devices.

What power should the cordless drill have, how heavy can it be and where is the price limit? This data can be set through the filters so that all other devices disappear from the product list. The limitation makes it easy for you to choose the right cordless drill from the test.

A very useful tool are the customer reviews, which are now available in almost every online shop. Whether it’s a hardware store’s online site or a comparison portal, reports from other buyers can help you learn more about the cordless drill, its advantages and disadvantages. Any difficulties with certain materials, the fast or somewhat tough customer service and many other experiences can play a role in the purchase decision . The displayed delivery time can also influence the selection.

The order itself only takes a few clicks and a few personal details. You have the choice between several payment methods, you can inform yourself about the fulfilled standards of the retailer with a look at the seal of approval and you only have to activate the final order. The delivery arrives a few days later and you can start drilling and screwing. If you are in a hurry, you can opt for express delivery, but in many cases standard delivery is enough to receive the cordless drill within two days.

For those who want to order tools and accessories more frequently, it is probably worth registering with the online retailer. Once you have entered your data here, it remains stored so that you only have to log in to the following order. This saves you having to enter your name, address and, if necessary, account details. This way, the ordering process can be accelerated.

As a regular customer, you often receive discounts and invitations to special promotions at some online shops. But some retailers also offer these special offers for new customers. On certain occasions you can take advantage of the hour and save a few percent or benefit from another discount. Compared to hardware stores and specialist retailers, the savings options on the Internet are significantly better.

Interesting facts & advice

If you inform yourself about the cordless drills , it is often not just about the product selection, but also about the correct handling. In principle , the cordless drill can be operated without a long explanation and training, but there are certain challenges even for experienced do-it-yourselfers. Clean boreholes can only be made if the advisor is followed , so that the material is not destroyed. You should also make sure that the planned drilling site does not meet a power or gas line and that there is no water pipeis in place. If necessary, you should use a line detector before drilling and screwing on the wall to check whether the affected area can be processed safely.

Before you start drilling a hole, it makes sense to mark the point at which the cordless drill is to be placed. Choosing the right drill is also important. The hole must not be too big for the dowel, so it is better to use a slightly narrower drill. The depth of the borehole may be a little longer than the dowel.

When drilling, hold the tool at about chest height and pay attention to the right angle to the wall. If the cordless drill is equipped with two gears, you can use the second gear, which is faster than the first, when using small and medium-sized drills. This first gear is suitable for the larger drill holes and for screwing.

When using a cordless drill from the test, you should make sure that the device does not overheat. By repeatedly pulling the drill bit out of the drilled hole, part of the drilling dust can be transported outside. At the same time, the thread is cooled. When pulling out, the drill should keep turning, because if it does not move, it can quickly tilt. For safety, you should concentrate on your drilling work on the one hand and control the surroundings on the other. If there are children nearby, the risk increasesof accidents. You also need a secure footing, even when working in the stairwell or on a higher level. If necessary, protective measures must be taken so that you do not fall or that other roommates are not harmed.

In addition to advice on quality features, safety and correct handling, many consumers want to know more about the development of the tools. There is extensive information on the historical background that is not only interesting for professional craftsmen.

The history of cordless drills

A look at the history of the tool shows that certain devices were used in the early days of mankind. The earliest traces of drilling tools appear to date from around 3,500 BC. However, other finds indicate that there was already a kind of drilling rig among the indigenous peoples. How else could these people have pierced stones? However, there are no clear signs of this assumption.

In the beginning, people used natural building materials to make a kind of drill. They made a kind of holder from knot forks and another piece of wood, in which there was a drill. This drill was made of horn or sturdy wood and was rotated using a bowstring, the so-called fidel. For this purpose, the bowstring of the bow was wrapped around the drilling element so that it was only necessary to pull it back and forth. So it came to the typical drill rotation. The rubbing effect was increased with moistened quartz sand , so that a hole was created in the machined workpiece.

For a long time there were only minor changes to this prehistoric drilling rig. Until the 10th or 11th century, drilling work was rarely carried out. However, as metals were processed more and more, the need increased. In the 11th century, for example, roller drills, racing spindles and drilling lyre were developed.

The roller drills continued to work with the Fidel, but the drill itself was a hand tool in which the drill was pressed onto the material by hand. In later times, this construction was supplemented by a hollowed-out nutshell or similar elements to protect the palm of the hand.

The racing spindles were two legs that were connected with a tensioned belt. This was led around the drill. When pressing on the spindle, the legs tightened, the belt tightened and caused the drill to rotate . A flywheel fixed on the drill shaft ensured that the belt was wound up correctly when moving back. The racing spindle was also known as the Dreule. Among other things, they were used in the Middle Ages to build instruments.

Following these early drills, which were driven with Fidel or belts, the early drilling machines with full mechanics were created. The drill bit is one of the typical tools of this type. Its most important element was the drill chuck, which had a shaft in the form of a worm thread. There was a handle directly on the thread, which moved up and down when rotating and was operated with one hand. The shaft closed at the top with a mushroom-like wooden plate that was held with the second hand. So you had good pressure when drilling. With the up and down movement of the handle, the thread was turned, so that the rotating drill bit a hole in the workpiecebored. These drill bits were very popular until the 19th century and can still be found in some traditional workshops.

The drill or chest lyre was a device that had a double bend. It was pressed together with the drill onto the workpiece to be machined. The double angulation created a crank that turned the drill into the piece. The drilling lyre has been around since the 15th century. With the invention of the electric drilling equipment, however, they lost their importance, even if some craftsmen continue to use the now refined chest lyre . The traditionally working carpenters in particular rely on the precisely working devices, which have been significantly improved compared to the earlier models.

Gun drilling machines were developed as early as the middle of the 16th century. These should make the gun barrels as precise as possible. The machines worked with a wooden structure in which the pipe blank was clamped. A block and tackle pressed vertically on the drill, at the same time the dead weight supported the force effect. A horse team was responsible for the rotation of this drilling system. In 1774, John Wilkinson optimized the gun drilling machine and thus ensured an even better result.

Pillar and column drilling machines were built around 1830. These were used in industrial companies as well as by craftsmen. They too are made up of the robust frame and a suitable drill. The drill presses were driven either by a crank that was turned by hand or by a foot pedal. With faster movements, the rotation of the drill accelerated.

With the use of electrical energy, the development of the tools went faster and faster. 1891 is the year in which the electrified drilling machine originated. At the Deutsches Museum in Munich you can admire a radial drilling machine, for example, that 600 kg weigh and rolled on wheels on the job was . The PTO shaft provided the transmission of rotation from the motor to the drill, while the propulsion was carried out by a handwheel. This large machine made it possible to drill up to 4 cm.

Wilhelm Fein, who founded a workshop for various devices in 1867, was considered a great inventor and developed the predecessor of today’s electric and cordless drills in 1895. He presented the SZ 3, an electric hand drill, making a big step into the world of power tools. This first electric drill had a stable body and two solid handles. It had an output of 50 watts and an operating voltage of 110 volts.

In 1914, Fein launched an electro-pneumatic drill that had a striking mechanism and was the predecessor of the hammer drill. The company C & E Fein was also known for its innovations in later years. Various power tools were developed here, for example an electric tin snips. His inventions have made Wilhelm Fein one of the most important founders in the field of electrical tools.

Other companies also followed suit. Siemens Schuckert was one of the first to join the development and presented an electric hand drill in 1900. It worked with 80 watts and had a housing made of light metal, which made it easier to handle than the device from Fein.

In addition to the electrical tools, the newly developed mechanical hand drills also met with great interest among customers. This mechanically operated drilling machine was a device made of metal, the drilling shaft of which was activated by an internal gear. With the hand drills, there was an early quick-action drill chuck. At the top of the device was a plate that could be used to easily create the necessary pressure when drilling. The crank, which was attached to the side, made the gearbox rotate and with it the drilling shaft. You could turn the hand drills both left and right.

In the 20th century, a lot happened in the further development of the drilling machines. The electrical devices in particular became more powerful on the one hand, and more comfortable on the other. In the 1930s, the company C & E Fein presented a drill with four gears and an output of 370 watts. This device could even drill into steel and had an extremely high speed with a maximum of 6,700 rpm. The setting options allowed different materials to be processed with it.

During the Second World War and afterwards there were changes in the technology of the drilling machines. In what was then West Germany, large companies such as AEG, Bosch and Siemens in particular were working on their drills, cordless screwdrivers and other tools. Thanks to their innovative strength, the machines, which used to be relatively heavy, could be developed into comfortable power tools . With the increased variety of electrical appliances, more and more private individuals became interested in it. The boom in the DIY sector also caused increased demand for the sophisticated tools.

While devices such as the Boschhammer became top sellers in western Germany, the BM10 was very popular in eastern Germany. This was a drill in an aluminum housing that worked without a blow and was extremely resistant.

However, it soon became clear that the classic drilling machines are not so well suited for precision work. Although they offer high performance, it is easier to avoid errors with the precisely adjustable drill drivers. In addition, impact drills and comparable electrical devices can wear the screws faster.

Added to this were the increasing demands of consumers and commercial users. Private hobby craftsmen in particular wanted lighter devices. That is why there has been a growing interest in cordless drill drivers since the 1980s . Consumers now often assemble their furniture themselves, and it is precisely in this area that modern cordless drills are convincing. Taking into account the ergonomic and functional requirements, some of the devices have become significantly smaller and more manageable, without having to sacrifice performance.

There have also been changes in battery technology in recent years . For a long time mainly NiCd and NiMH batteries were used for the cordless drill. The Li-ion accumulators, whose success story began in the 1970s, were quick to win through with their lighter weight and better performance characteristics and can therefore also be found in the new test winners of the cordless drills.

Numbers, data, facts about the cordless drill

The cordless drill is a useful tool that is also often used by laypersons. In fact, this device is the most frequently used cordless tool in German households.

The bolting of furniture, attaching shelf shelves and baseboards or hanging picture frames, making it done much faster than when using a screwdriver. The cordless screwdriver is used here as a convenient tool .

In the test of the cordless drill, the mini models were examined as well as the robust and powerful electrical devices in standard format. With the larger versions, users often have two gears to choose from: the first is used when you want to tighten or unscrew screws, the second is more suitable for drilling. In the second gear, the speed range is higher than in the first gear, which creates a larger drilling diameter and also penetrates better into hard material. When working with the cordless drill, you can use a little more force or you can drill and screw more sensitively : This prevents the screws from over-tightening. If you don’t dare to do this fine workmanship, there are cordless drills with adjustable torque.

In general, modern cordless drills are equipped with powerful lithium-ion batteries that can be easily removed for charging. Only with the mini screwdrivers can the battery be permanently integrated in the device. Batteries are sometimes used in the small format models. Both systems restrict the energy supply and thus the possible uses. The miniature screwdrivers can be used to reach difficult places.

With the powerful battery tool , long-term work can be carried out without a break if the battery has sufficient capacity. If necessary, this time can be extended with a replacement battery. Those who want to drill and / or screw continuously should still ensure that the batteries last as long as possible. The ampere hours provide information about the duration of the assignment. With the standard screwdrivers from the test, the battery power is normally 3 Ah and more. Compared to the Li-Ion batteries, the NiMH batteries that were often used earlier are not as durable, which is why you can hardly find them in the new battery-powered drills.

In addition to the battery performance, the battery voltage also playsor nominal voltage play a major role in the selection of a cordless drill. The cordless screwdriver becomes stronger as the voltage increases. An operating voltage of 10.8 volts is sufficient for most screwdriving work and also for some drilling work. With many cordless drills, a voltage of 14.4 or 18 volts provides a little more power. But in general, this higher battery voltage is more likely to be found in cordless impact wrenches, which not only work more powerfully, but also have a higher weight. So the question arises for which projects you need the cordless drill and how often it is used. The mini devices sometimes only have 3.6 volts. From a battery voltage of 12 volts, it makes sense to use a model with two gears.

Use the cordless drill correctly in 8 steps

On the one hand, drilling and screwing is simple, so that the use of the cordless drill is almost self-explanatory. On the other hand, there is always a certain danger when handling battery tools. That’s why you should know a few basic rules and follow them, otherwise accidents and even injuries can occur. Information about the correct position, the drilling angle and the use of dowels and screws is not a matter of course for every layperson. The environment and materials should also be examined to find the appropriate drill and to avoid using a power lineor hit other sensitive areas in the wall. The experienced craftsman knows how to use the cordless tool and unconsciously carries out the following steps. This instruction is intended to be a useful aid for beginners.

  • Step 1

Before you start the battery drill, you should check the place where the hole is to be drilled. To do this, you have to check the wall for power lines, water pipes and metals. For this purpose, there are suitable location and testing devices that are guided along the wall surface. In general, the power lines in the existing installation zones are laid vertically and horizontally. Here you can use the sockets as a guide. The horizontal pipes often run between 15 and 45 cm from the floor and ceiling. The cables can also be in the area between 10 and 30 cm next to the door frame, window frame and corners.

  • step 2

After marking the borehole, a tap test is carried out. If the wall sounds hollow, it’s probably a lightweight material like plasterboard. A rather dull knocking tone indicates that the wall is solid and made of concrete or natural stone. Depending on how firm the wall is, a more or less strong drill is used.

  • step 3

A suitable drill is selected to match the nature of the wall. This is also matched to the diameter of the anchor. With a more porous wall, it is better to use a slightly smaller drill diameter. This prevents a hole that is too large. The drill is inserted into the drill chuck and securely fastened here. All you need to do is tighten the front part of the drill chuck.

  • Step 4

The drill hole should correspond to the length of the dowel or be a little longer. To ensure the correct drill hole depth, you can mark the spot directly on the drill. Colored adhesive tape is suitable for this, which is also clearly visible when screwing. But there are also some cordless tools that are equipped with an adjustable depth stop.

  • Step 5

When drilling, you should be sure whether you hang a lamp in the stairwell or attach something to the wall a little further up. It is not always possible to stand steadily on the floor with both feet. Ideally, you build yourself up in front of the wall with the cordless drill in your hand and take a small lunge. If you operate the tool with your right hand, you put your left leg forward, while your left-handers stand with your right leg forward. You can also stand slightly offset on a ladder or on the stairs. This is safer than if the feet are placed parallel to the wall. In case of doubt, you can get help from a second person who secures the ladder or in the meantime removes the tools.

  • Step 6

To drill the hole in the wall, the battery drill is placed at right angles to the wall surface. Now the rotary drilling function is switched on in order to drill through the plaster at a constant pressure. Drill to the depth of the drill hole and carefully pull out the drill while the turning function expires. Depending on the nature of the wall, you can switch off the device first and then pull out the drill. If you want to avoid drilling dust on the floor, you can simply stick an envelope open underneath the borehole. Or you can ask a second person if they can use a vacuum cleaner under the drilling site to collect the dust.

  • Step 7

For the dowel, the borehole must be cleared of the dust in it. You can do this with a vacuum cleaner or with a dust brush. The dowel finds a better hold in the cleaned borehole.

  • Step 8

When the hole has been drilled, check its diameter and depth using the dowel to be used. If the borehole is not sufficient, a second drilling operation with a stronger drill must be carried out. If the hole is too large, you can work with filler and then push the dowel into it. The excess mass must be removed before the screw is screwed in, and it also takes about two hours to harden. Then the screw has the correct hold.

There are similar tips for screwing with the cordless drill. The direction of rotation plays a relevant role here: when tightening screws you have to set the cordless drill to the right, to loosen the screws you have to switch to counter-clockwise rotation. You should also make sure that the speed matches the current assembly or construction project, so that the screws do not wear out and are still tight.

10 tips for care

A powerful cordless drill test winner from one of the top manufacturers scores with a long service life. The technology is becoming more and more mature, but the somewhat older models are proving to be indestructible and are often passed on from one generation to the next. So that the cordless screw drills can still be used after several decades, they need a certain amount of care. Some elements can be replaced in no time, but the device itself should be handled carefully and cleaned properly after use. The following 10 tips show how this works.

  • Tip 1

If you mainly tighten and loosen screws with the cordless drill, no chips are formed. Only fine dust grains can arise. That is why you usually do not need a complete cleaning after screwing. In most cases, you only have to wipe the tool dry, ideally with a lint-free, soft cloth. This regular wiping after use prevents the gear unit from being contaminated by dust particles. The device motor cannot overheat in the following project.

Tip 2

Every now and then a more thorough cleaning of the cordless drill is necessary. A vacuum cleaner, fine cleaning brushes, cleaning rags and special polishing utensils are used for this. Especially if the cordless drill is also used for drilling and chip residues arise, it is important to carefully remove these residues.

Tip 3

The area in which the cooling slots are located is particularly sensitive. At this point, the dirt and dust particles can penetrate inside the device. If the ventilation ducts block, consequential damage will soon occur. The cooling slots can be vacuumed out with the vacuum cleaner. Compressed air is not a good solution because it could blow the dirt even further into the device

Tip 4

So that the battery lasts as long as possible, you should follow the instructions for charging and maintenance. Depending on the type of battery, the tips may look different. The most commonly used Li-ion batteries can only withstand the full charge current if their charge level is the correct depth. However, deep discharge should be avoided, as should the full battery capacity of 100%. Before using the cordless drill, you should check whether the minimum charge level is given, which is recommended for use. Compared to other types of batteries, the Li-ion batteries are unaffected by the memory effect, which is worth knowing when charging.

Tip 5

The charger, like the cordless drill and the battery itself, can take some care. That means: if it is not used, you should not leave it open, but put it away. It often finds a place in the tool case of the cordless tool. In addition, you will find in the product description of the charger that you should not keep the charged battery in the charger at all times.

Tip 6

A battery that remains unused for a long period of time should neither be fully charged nor completely discharged. The Li-ion batteries remain particularly durable if you charge them half-way for storage. When storing batteries, it is important to avoid extreme temperature fluctuations. The Li-ion batteries must not be exposed to excessive heat, so they should not be in the car or in the garden shed on hot summer days. The batteries lose their capacity if they overheat.

Tip 7

The cordless drill should be kept in the appropriate tool case after use. In this case there are often the correct slots for the accessories of the device. Even if you store everything in the suitcase, it should be safely stored. The tool and its accessories must never be damp.

Tip 8

There are special boxes or storage systems for the drills and bits, some of which are also stowed in the tool case of the cordless drill. Correct sorting helps you to quickly find the attachment drill you are looking for, and the neat system prevents the smaller and larger drills from being lost.

Tip 9

Tools such as cordless drills should only ever be used for the work for which they were developed. Certain areas of application and materials are unsuitable for the devices. If you do not follow the manufacturer’s instructions, you can expect the drill to be damaged and the durability to be shortened.

Tip 10

Material protection can be used to protect the cordless drill from Test 2020. The tool experts offer special corrosion protection with which small traces of rust can be removed. With such protection, the durability of the cordless drill can be extended, at the same time the devices look like new again.

Useful accessories

Various accessories are available for the cordless drill from the comparison test. This should make work in the private household and in the commercial area easier. Whether you perform minor assembly work or participated in difficult construction projects, the battery drill equipped with carrying case and other parts must.

The tool case is part of many cordless drills and contains not only the standard battery, but also a spare battery and a drill set . If necessary, you can also buy a single transport case and also get the other utensils separately. The small parts are ideally contained in a stable storage box so that you cannot lose them. At the same time, these systems help to create order. Especially the thin inserts for the smaller cordless drills from the 2020 test should not be thrown into a big pocket. A case or a practical box is better here to keep an overview and to avoid having to search for a long time when doing DIY.

The typical bits for the handy cordless screwdriver show a taper on the mounting shaft u. The classic hexagonal shank has a different shape and therefore cannot be used for such a tool. Only the compatible inserts are therefore suitable for the special bit holder. However, the cordless screwdriver bits can also be used in a conventional drill. However, you have to take into account that they are not as resilient as the actual use for the drill.

The special accessories for cordless drills include, for example, special drill bits and inserts for plasterboard walls or for other materials. Other drills have a special tip or elongated notches that increase the impact. However, such an extra is used less in the cordless drill than in the powerful hammer drill.

To ensure the necessary stability, make sure that the drill bits have a special hardening. Only then can the higher torques be transferred correctly, even if you work with a blow. The other option is to work with different drills, one of which is used exclusively for the cordless drill, while the other is suitable for the rotary impact wrench. Cheap and weak bits can break off quickly and the inferior material can also damage the bolts and nuts.

In addition to the cordless drill, the complete equipment in the workshop also includes other devices that even laypeople can hardly do without. Hand tools such as hammers, pliers and screwdrivers are irreplaceable, because especially with the slightly larger cordless screwdrivers you cannot get everywhere. Even more important is the charger, which is not necessarily included in the scope of delivery of the cordless drill from the test. When setting up a private hobby workshop , it is advisable to coordinate the devices so that the batteries can be replaced directly. This saves the purchase of individual replacement batteries in different sizes, because the devices all work with the same battery.

A folding rule, spirit level, current tester, craftsman’s pencil and other utensils help with the preparatory work required for drilling. Often these devices accumulate little by little. Some of these tools and aids are included in a multi-part package, so you don’t have to buy everything individually.

The further equipment of the own workshop includes, for example, a workbench, a saw, a stable tool cabinet and plenty of space for the various devices and small utensils. A kind of mobile home workshop that can be used as a suitcase, box or rollable tool cabinet may also be useful. Not only the smaller tool cases are suitable for transport, but also mobile boxes in large format. However, these are used more by the professionals and rarely by private do-it-yourselfers.

Additional protective measures are recommended for certain drilling operations. If you drill overhead, you need protective glasses , for example . In addition, an extraction system can be helpful, which removes the dust directly at the drill hole. Hearing protection makes sense for people with sensitive ears, even if most cordless drills are quite quiet compared to drills.

Alternatives to the cordless drill

A cordless hammer drill is very similar to the cordless drill , but it also has an impact function. This also allows drilling in masonry. If the walls are even harder and made of concrete, the even stronger hammer drill must be used. You can recognize this device by the typical SDS lining. Both the cordless hammer drill and the hammer drill have a higher weight than the cordless drill, which makes fine work difficult. In addition, they shoot with their power over the target, so to speak.

As an alternative, a drill that works with electricity may be suitable. In contrast to the cordless drill , you need a power source here, because the drill cannot be started without a cable . The drill is therefore less flexible and you have to be more careful when doing the drilling and screwing. Due to the connection to the mains, there is no need to think about charging the battery. In most cases , the power-operated drills are heavier and more powerful than the cordless drills from Test 2020. They are therefore also suitable for somewhat harder materials.

The screwdriver is the simple variant, but it requires the most effort because you have to screw by hand. You can work very precisely with the hand tool, but it takes longer. In the meantime, many people prefer to use the mini screwdrivers with rechargeable batteries , which are almost as handy as the screwdrivers and save them having to turn around all the time.

Some hand screwdrivers work like a ratchet and are very easy to grip. It is a kind of compromise between the simple screwdriver and the cordless drill in mini format.
