  • Belt speed: The possibility of adjusting the belt speed, generally the preserve of the most expensive products, is an advantage for the user as it allows you to better adapt the tool to your specific needs.


  • Paper consumption: At maximum speed, the abrasive paper tends to wear out very quickly.


Rank #3: SKIL 7500 Belt Sander

Power and precision. With these two words, it is possible to define the device made by Skil, one of the best sanders for sale online.

A 650 Watt motor  guarantees effective removal of the material even when working on rather large surfaces.

As for precision, however, the automatic belt centering mechanism always keeps it in perfect position, ensuring accurate and smudge-free machining.

 The design is extremely compact and conveys a pleasant sensation of durability, further enhanced by the goodness of the body plastics.

The ergonomic design of the handle ensures a perfect grip with both hands, while the presence of the suction system for processing residues in the unique bag allows you to keep the environment clean. 

Some buyers, however, have found that the shape of the Skil makes its upside-down use complicated.

This should be an essential feature for you, better opt for another model.

Thanks to the excellent quality/price ratio, Skil quickly climbed our rankings, ranking third in the guide to choose the best belt sander for sharpening knives of 2020.

Here are his strengths and weaknesses.


  • Power: The 650 watts of power are more than enough to allow Skil to perform any type of work with efficiency, speed, and little effort by the hobbyist.
  • Accuracy: The work is always clean and precise thanks to the automatic centering mechanism that keeps the belt still in the right position.
  • Ergonomics: The Skill can be used using both hands as it has a compact and ergonomic design that facilitates maneuverability.

  • Upside down use: The unique design of the power tool makes it difficult to use it upside down.

Rank #4: TACKLIFE Belt Sander

The TACKLIFE is the new model of belt sander produced by the Tacklife company, belonging to the Chinese giant Aukey Technology, and is an extremely versatile model designed for a wide range of applications, as long as they are non-intensive and of an exclusive hobby nature.

It is driven by a 600 Watt motor capable of generating an adjustable speed from 0 to 560 rpm, via the specific control dial.

 It is designed for connection to a dust extraction system and can also be fixed upside down to a workbench, thanks to the unique metal clamps supplied with the accessories.

The latter is very generous and also includes seven abrasive belts with 80 grain and six with 120 grain, two different adapters for vacuum cleaners, a dust collection box, the instruction manual, and the 24-month warranty.


  • Versatile: It can be used both in manual mode, with comfortable ergonomic handles, and in stationary mode; in the upper part of the body, there are two holes in which it is possible to insert the clamps to fix it on the workbench in an inverted position.
  • Double adapter: The predisposition for connection to the vacuum cleaner is equipped with two different adapters, one 32 and one 35 mm, to maximize compatibility.
  • Well equipped: The equipment includes two adapters for the suction system, two clamps for fixing to the bench, the dust container, and thirteen belts, one of which is already mounted on the sander.


  • For hobbyists only: It is an excellent sander but suitable only for hobby use; if used too intensively, the belt tends to go under stress and drastically slow down the run.

Rank #5: Makita Variable Speed Belt Sander

The Makita  is a belt sander not very dissimilar from the Tacklife examined previously. It is placed in the same market segment both as regards the price and the intended use.

This is also driven by a 600 Watt electric motor and is equipped with a speed regulator.

 The latter can be set on seven different levels, from 360 up to 560 rpm, to optimize the performance based on the type of material to be treated.

It is equipped with an ergonomic handle and lock switch so that you do not have to keep the power button pressed during prolonged use, especially when it is fixed in an upside-down stationary position.

Like Tacklife, however, the Makita  is also an economic sander designed primarily for non-intensive hobby use.

 This does not mean that it is versatile enough and capable of working on different types of material.


  • Economical: The price is among the most convenient that can be found on the market; even if slightly, in fact, it is even lower than that of the Tacklife sander. So it is appreciated above all by less demanding hobbyists and more attentive to savings.
  • Well equipped: Characterized by a generous supply of accessories: there are twelve abrasive belts, and there is only one adapter for the dust extraction system.
  • SDS: The ease of use of the Ginour sander also extends to changing the belts, thanks to the patented SDS system, like Tacklife. Moreover, it can be used in stationary mode by fixing it to the workbench in an upside-down position.


  • For hobbyists only: Compared to the Tacklife, it has the advantage of being less noisy, but it is still an electric tool with exclusively hobbyist performances; if you want a more powerful appliance, you will have to move towards a more expensive model.

Rank #6: SKIL 7510-01 Sandcat Belt Sander

This belt sander made by SKIL belongs to the Compact Expert series, a company that is a guarantee for all lovers of DIY and DIY.

 It is a product that makes its distinctive features of compact size and secure handling, which it combines with a high removal capacity, even on large surfaces.

What is our opinion is the best belt sander for sharpening knives of 2020 has the electronic adjustment that allows a smooth and gradual start, as well as the possibility of preselecting the number of revolutions? 

Among the appreciations expressed by its buyers, the sturdiness and handling combined with indeed contained vibrations compared to other similar products should be noted.

The SKIL model is equipped with a Microfilter system that conveys the dust produced during processing directly into an ad hoc container, to ensure that the work area is always clean.

 The selling price fully reflects its potential.

The model made by Bosch has therefore met with great success among many consumers, as can be seen from the numerous enthusiastic opinions and as often happens when the prestigious German company is involved.

Here is a summary of the strengths and weaknesses of the Bosch belt sander.


  • Ease of use: The compact design and extraordinary maneuverability make the power tool easy and practical to use. Work is ultimately much more comfortable.
  • Soft start: Thanks to the electronic adjustment present in the new model made by Bosch, the beginning is smooth and without annoying repercussions.
  • Materials: The construction materials are resistant and destined to last over time. Furthermore, the vibrations reduced to a minimum allow to operate with maximum comfort.
  • Microfilter: Thanks to this system, the dust that is inevitably produced during processing is immediately conveyed into a particular container, thus leaving the area on which it is operating clean.


  • Noise: The medium-high noise that is found does not seem to be the strong point of the power tool.

How to use a belt sander

Those who work with wood (but not only), even if for a simple hobby, cannot exempt themselves from having a good belt sander. It is a powerful tool that finds its use in finishing works for different types of surfaces. In addition to wood, metal, ceramic, etc. can be sanded. Basically, what does a sander do? Remove excess material from a surface until it becomes uniform. There are three types of belt sander, which is the one we are most interested in, orbital and random orbital.


Let’s focus on what are the characteristics of the belt sander. A fundamental element is the abrasive paper, which runs on two rollers. This type of power tool lends itself well, especially when you need to work quickly on large surfaces. Furthermore, a sander can be a bench or a manual one. The choice depends on personal needs and the types of work that you usually do. If you are a professional, it is better to have both versions to cope with any kind of eventuality.

Tension and center the abrasive paper

One of the first operations to be performed is to check the distance between the rollers. To do this, a small lever is used to stretch the abrasive paper. It is equally essential that the card is centered. In this case, a screw is turned, which is usually located on one of the sides of the tool.

The ignition

One of the most common mistakes of those who have never sanded before is to place the tool on the workpiece and then operate it. In reality, it is advisable, for a good sanding, to first set the switch to On and only after that place the sander on the piece.

Proper sanding of wood

For wood, in particular, it is essential that you start from the point where the vein is located and then proceed along it. It is necessary to pay close attention to the pressure exerted to avoid the formation of furrows. It is probably superfluous to say how the paper should be changed with a certain periodicity, being subject to wear.

The residues

The sander inevitably produces waste, or if you prefer, let’s call it residue. These will have to end somewhere. Included, at least in most cases, your sander will have a bag to collect dust. However, if you work on several materials, it would be more appropriate to connect it to a vacuum cleaner bin.

Buying Guide – How to choose the best belt sander?

Among the tools that could be useful in DIY and do-it-yourself jobs, there is undoubtedly the sander, a device designed to smooth and file metal, wood, or ceramic objects.

On the market, there are different shapes, sizes, and prices, and to help you understand which is best suited to meet your needs, we have created this guide that highlights the aspects to be taken into account when purchasing. Besides, you will also find reviews of the most popular sanders for hobbyists and professionals.

Various types of abrasion

Beyond the body of the sander, driven by an electrically powered motor, the real characteristic feature of this type of equipment is the rotating abrasive blades, those who, in contact with the various materials, perform the sanding operation.

By comparing prices and models on the market, you will notice that it is possible to find discs in three different materials, each suitable for different types of processing. There are, for example, those in diamond, in silicon carbide, or corundum. The latter is the most “tender” of the three. Silicon carbide is characterized by high hardness while the diamond is even more resistant and capable of withstanding even the most elevated temperatures.

There are also models that “accept” the sandpaper for sanding. Typically there are two versions: the sanders that are used with regular sandpaper, fixed on a clamp, and those that host strips equipped with velcro, more comfortable to use and to replace. The price to pay for this convenience is a higher average strip cost.

Finally, some models of the best brands are equipped with both a clamp and velcro to allow you to choose, from time to time, what type of sandpaper to use.

Orbital or ribbon?

Regardless of the type of blades, the sanders can be divided into three categories: portable, more comfortable to handle and suitable for smaller jobs, especially for DIY; belt, useful for carrying out a roughing operation which must be followed by finishing with a smaller appliance; orbital, more demanding to use and often equipped with holes capable of eliminating the dust produced by grinding.

In our ranking of the various types of sanders, we cannot fail to mention the angular and roto-orbital models that combine the orbital movement of the part intended to smooth with the rotating one. This tool model is mainly used to make exact filings if not even to polish, for example, the bodywork of a car.

Power and power

Depending on the model, the motors of the sanders are capable of releasing a power that varies from a few hundred watts up to a maximum of 2 kilowatts. However, the most influential models are suitable for professional uses and industrial processes.

The moment you find yourself choosing, our advice is to opt for an electric tool that ensures at least 7 / 8,000 revolutions per minute, and that guarantees excellent handling.

Many of the models capable of satisfying these characteristics are battery powered, designed to meet the needs of lightness and ease of transport. Possibly, there are also versions with the cable to be connected to the power outlet, which you will not have to remember to charge but which, due to the length of the wire, guarantee less freedom of movement.

This is how the belt grinder was tested

All belt grinders have undergone extensive use in external tests and had to face some challenges. It was always based on the information provided by the manufacturer and, for example, found out to what extent the manufacturer’s information coincides with reality and whether the grinder does what the manufacturer promises.

In various tests, important factors relating to the order and delivery, as well as the packaging and the data on the belt sander itself have been incorporated. The practical test was primarily based not only on an experienced user with a handicraft background but also on a layperson. The tests were carried out from both perspectives, which made the results even more precise and made an unreserved recommendation.

Each manufacturer specifies with its belt grinders which surfaces they are particularly suitable for and whether they are only used flexibly or stationary. If a belt sander contained accessories, this was included in the test. The same also applies to the connection to an external suction device , so that feedback could be given on the integrated dust bag with suction, as well as on the connection to the external device.

Price and performance, as well as performance, abrasion, and noise in use were decisive criteria in all belt sanders in our comparison.

Only if a device was fully convincing did it get a very good rating. No requirement was left out in tests and even difficult situations, such as very solid materials or multiple layers of paint on metal, were included.

It is therefore not just a result that was determined in a short application and with favorable conditions in the test. In these external tests, everything that is important for a good belt sander was checked and so it was determined for you which device showed positive results in all criteria and thus made the best decision when buying.

There are these different types of belt grinders

There are stationary and flexible grinders , but also devices that can be used in one as well as in the other application. In the case of combined devices, it is particularly important that the brackets for the attachment provide real strength and thus the necessary safety when working.

There are also differences in the company itself. Belt grinders with or without a cable , i.e. with electrical operation and with a battery, characterize the wide range of manufacturers. In order to make the right decision as a buyer, the selection should primarily refer to the models that convince for the planned use and emerge as comparison winners in this area .

If you want to use a belt sander flexibly on different construction sites, you are well-advised to use a battery-operated model and should not use a purely electricity-powered device. In-home use or when used in the workshop, belt grinders with a power connection can certainly convince, since they are permanently connected to the mains during operation and can therefore function constantly.

Since there are also differences in the width of the grinding surface, the main size of the surfaces to be ground should be considered in the decision. The larger the grinding surface and the wattage, the faster the work leads to the desired result. A belt sander with battery operation does not necessarily have to produce a lower power compared to a model with a power connection.

The only decisive factor is the wattage and the speed, which leads to advantages in an individually adjustable form. Belt grinder is not the same as a belt grinder, as you can see in our comparison and can, therefore, use it as the basis for your decision for a model, an operating mode, and a performance.

Some devices have a grinding rail that keeps the distance between the belt sander and the surface constant. This rail can provide advantages in professional use, but also for laypersons, and avoid creating grooves in the ground material through individual pressure.

There are also models that are equipped with automatic adjustment of the grinding surface and are therefore particularly suitable for grinding work with execution up to the edge or near the wall. Here the sanding surface automatically follows and no manual adjustment of the sanding belt is necessary.

This is how a belt sander works

The belt sander is placed on the surface to be processed and is designed with an abrasive belt that is provided with the desired sanding paper with the appropriate grit size. Under the paper is the sanding block, which in the belt sander is not made of wood, but of a sustainable material such as graphite.

The movement of the sanding belt is caused by the electric motor, which ensures constant performance and constant movement. In contrast to manual grinding, on the principle and movement of which the belt grinder works, the surface, which is called abrasion during belt grinding, can be removed in a short time.

Due to the constant design, the movements of the sanding belt ensure a uniform result and shorten the working time compared to manual sanding with sanding blocks and paper.

The user decides whether to carry out a rough or fine sanding and how much surface should be removed by choosing the sanding paper.

However, the revolutions per minute also play an important part in the working speed and the result. The more revolutions per minute a belt sander makes, the greater the abrasion and the faster you will achieve the desired result.

The combination of the correct grit of the sandpaper and an optimally selected speed for the material ensures a smooth and streak-free surface. The electric belt sander does not work with physical strength, so the pressure on the device does not lead to a better result, but to damage to the surface and an uneven, dimpled or grooved result.

What does a belt sander have to do?

The belt sander is a simple, but very effective tool for surface processing. Compared to eccentric, delta or angle grinders, the belt grinder removes most of the material in the shortest possible time. The preferred area of application is the processing of large wooden surfaces, but concrete, varnish, and metal can also be sanded off with the right sanding paper. If you want to do fine work, grind tight corners and angles, the belt sander is the unsuitable device.

The sophisticated functional principle results in high stock removal: an abrasive belt runs over two rollers, which are located at the front and rear on the underside of the device. In contrast to an orbital sander, the drive roller sets the belt in only one direction, the steering roller centers the abrasive. The resulting linear grinding pattern is particularly suitable for grinding wood with the grain.

What types of drives does a belt sander have?

Like almost all hand-operated tools, you also get the belt sander with different energy supplies. The most used operating mode is with electrical current, which always ensures the same high performance until it is switched off. You need a generator on construction sites, at home a cable reel is sufficient if the location is further away. This connection is not necessary for battery operation. When buying, pay attention to the capacity and the term. For larger tasks, it is always worth connecting a second battery to the charger. In larger craft businesses, the compressed air-powered variant is another option. Here, the belt sander is used stationary, since the drive works by means of an air compressor.

Compressed air devices are more expensive to buy and more expensive to operate than power and battery devices.

What is the belt speed?

The speed at which the belt travels in the machine is called the belt speed . This parameter allows conclusions to be drawn about the maximum performance. A high belt speed enables fast and smooth grinding with less pressure. Processing takes longer at a slow belt speed, but depending on the material, a slower speed is necessary to keep the heat development within limits. Slower running is a bit of a hindrance on uneven and rough surfaces.

The band surface

The belt area indicates how large the entire surface of an abrasive belt is. The paper is always slightly wider than the sanding plate of the device. For this reason, the information on the belt area is not the same as the sanding area of the device, because with some types of paper the grain size does not reach the edges.

The grinding surface

The grinding surface designates the dimensions and thus the contact surface of the abrasive. Small sanding surfaces are suitable for working on narrow slats on a bench or garden fence, for larger surfaces there are correspondingly larger sanding surfaces on the market. If you grind a larger area with a small sanding surface, the result will be more uneven than with a flat support. You can also sharpen and polish knife blades with a special grinding belt and grinding paste.

What functions does a good belt sander have?

When choosing your belt sander, pay attention to high-quality equipment that makes work easier. Below we have summarized the most important properties.

Easy band change

A quick exchange of the sanding belt saves time and nerves. In the past, the belt had to be threaded and tensioned through a complicated guide. During the exchange, it happened that the craftsman had to fish out fine scraps of torn paper from the drive. Today the exchange works with a special device.

Integrated dust extraction

Abrasive dust in the air is irritating to the eyes and can cause lung diseases and allergies if inhaled. The sanding motions cover the work area with abrasion, which means that the sanding belt picks up the dust again and “clogs” the grain. Look for an integrated dust bag or the possibility of connecting a vacuum cleaner.

Automatic sanding belt centering

This function ensures that the sanding belt runs straight on the sanding plate. Without automatic alignment, the grinding movement makes it easier for the belt to tear or jump off the rollers. Not all belt grinders have automatic centering, but this equipment is noteworthy because it increases the productivity of the abrasives and enables effective work. On many models , a rotary knob on the front of the belt sander holds the belt in the correct position.

Adjustable revolutions

The faster the belt moves, the more material is removed. Take this into account with sensitive materials, as high speeds inadvertently remove too much from the surface. Modern belt grinders can usually be set to different speed levels or are equipped with electronic speed control.

Ergonomic design

Comfortable handling is particularly noticeable if the grinding work takes a long time. A position as natural as possible prevents fatigue of the arms. Make sure you have a non-slip soft grip that fits comfortably in your hand. This enables the powerful machine to be guided safely, even with sweaty hands.

Locking switch for continuous operation

You do not need to keep the button pressed by means of a lock. In contrast, a momentary switch should also be integrated in order to rework less successful areas or forgotten places (“Sundays”).

The weight

Hand-held belt grinders weigh around three kilograms. Stationary machines weigh at least seven kilos, including professional combination models  with belt grinders and grinding wheels that weigh 15 kilos.

Low vibration run

Make sure that devices that are to be used regularly and for a long time are extremely quiet. Excessive vibrations create uneven surfaces and you often need a break because your arms have fallen asleep. The decibel number also decreases with smooth running.

For larger projects, such as sanding a parquet floor, we recommend wearing personal protective equipment. These include safety glasses, a dust filter, mouth protection, hearing protection and gloves. Padded knee pads are comfortable when working on the flooring. Make sure that other people in the room do not smoke.

Who is a belt sander suitable for?

Belt grinders can be found in the hobby cellars of do-it-yourselfers and in commercial workshops. This very specialized power tool saves tradesmen the laborious task of sanding by hand. The belt sander was developed from the first foot-operated machines. The first electric grinders entered the market in the 1950s, but it was not until the end of 1988 that the Bosch company registered a patent for the first belt grinder.

When making a purchase decision, the user is asked to choose a stationary or mobile device. For the hobby area, we recommend belt sander sets with accessories, with which a handheld device can be attached to the workbench with the grinding surface facing upwards. Buying a set is also worth the price for a professional belt sander because buying individual parts is becoming more and more expensive. With the mounting option, the possible uses expand significantly without immediately buying a larger plate and belt sander.

Customers see belt grinders in the commercial sector for shoe repairs, which precisely aligns the new heels and soles. All professions dealing with woodworking use belt grinders for the production of consumer goods, furniture, wooden toys, and in industrial production. Mechanics in orthopedic technology also need belt grinders to individually adapt to plastic prostheses. Belt grinders are part of the basic equipment in the workshop in metalworking and construction, in agriculture, and for knife grinders.

 The Proxxon brand offers special  mini belt grinders for the hobby area and fine work. With 10 x 110 m sanding surface and sanding arm that can be swiveled by 60 degrees, small openings and grooves can be sanded out, profiles chamfered or precision parts reworked.

Free and guided grinding with the belt sander

You can extend a stationary belt sander with a parallel or angled stop to produce workpieces with a specified angle. The carpenter uses this device to manufacture built-in wardrobes, for example, and cuts tailor-made strips. With enough practice, it is also possible to guide the workpieces freely without an angle stop. In this case we recommend that you wear gloves because the rotating sanding belt does not differentiate between a wooden bar and your finger. Make sure that a spectator joins you on the side from where the belt sander pulls the workpiece away.

Disc grinders also offer interesting options. The sanding plate is the second option on various belt sanders to machine workpieces. The combi tool can be used to carry out rough preliminary work as well as to precisely form small parts on a relatively large grinding surface. The belt sander is a helpful tool, especially in model making, even when it comes to dressing components. A felt disc can be used to polish metal and natural stone in jewelry production or in blacksmiths for handicrafts.

On a large scale, the polishing of mineral materials is common in order to give luxurious furnishings a noble finish, for example on the worktop and mantels up to memorial stones made of marble, granite or other natural stone.

How does the belt sander achieve optimal grinding results?

Several factors influence the quality of the sanded surface. It is important to replace used sandpaper in a good time and always buy enough abrasives to change before starting the project. Never use the same sandpaper to sand metal and later wood. The grain should also be matched to the surface.

How can grinding marks be avoided?

Start the belt sander before the workpiece and the grinding surface touch for the first time. Always run the device parallel to the ground, never at an angle: Otherwise unsightly scars will appear that are difficult to remove. A smooth surface to bare wood is formed when the wiper lead in a straight forward direction parallel to the wood grain. Circular movement is more advantageous , for example, on painted surfaces.

Apply a lot or little pressure?

Always glide lightly over the surface, because excessive pressure creates surfaces with grooves. in addition, they put unnecessary strain on the drive and high frictional heat is generated. at high pressure, the sanding paper wears out much faster and you tire yourself faster.

If you are concerned with high material removal from wood, guide the belt sander with coarse paper across the grain. However, the surface becomes rough, so that a smoothing fine-tuning in the grain direction is then necessary.

Which abrasive for which material in woodworking, sandpaper with a grain size of 40 to 320 is usually used. Coarse sanding always uses sandpaper with a low grain size; subsequent sanding passes refine the surface with larger grit numbers. The belt sander is often used when renovating wooden doors and window frames. A fine tape only removes old layers of paint without removing anything from the material. The advantage of furniture refurbishment is that the belt sander does not scratch any squiggles into the wood, as happens quickly with an orbital sander. Our tip for sanding flat surfaces: Draw very light, generous serpentine lines with a pencil on the wooden surface to be sanded – then you can see from the remaining lines exactly which surfaces still need to be sanded.

Steel sheets, beams and other metal parts can be effectively trusted with the belt sander. Old layers of paint are also removed in a short time. With suitable finest grits of 4000 and 5000 no traces are created and felt disks can be polished on metal surfaces. Aluminum, like zinc, copper, bronze, brass, white and non-ferrous metals, is generally easy to machine. Iron and ferrous alloys are not suitable because the chips get stuck in the sanding belt and cause it to tear off.

The sanding belt can be cleaned

It is in the nature of things that after a long period of use, the sanding belt with deposits of wood abrasion, paint particles, or resin becomes clogged. You can make the sanding belt ready for use again with a simple trick: take an old plastic cutting board and sand it. A worn-out sports shoe is also suitable for cleaning the sandpaper, the rubber sole of which erases the sandpaper again.

The cost of a belt sander

If you want to renovate yourself or buy a belt sander for the DIY hobby, the price range is of course based on the budget. If the financial framework is tight or other investments are planned, you should consider the purchase carefully. How often and what will the grinder be used for in the future? Do you own a garden where there is always something to do or do woodwork as a hobby that you want to intensify? Since a belt sander is one of the longer-term and expandable power tools, we recommend taking a look at a current belt sander test first. In comparison, you can see quite clearly in which price range good devices for their needs are located.

As usual, the rule of thumb applies: those who save at the wrong end are dissatisfied in practical use. It is no fun if the no-name belt sander simply stops or even burns under the slightest load. For occasional use in the house and garden, you get decent quality from just 70 euros. This is certainly not a prohibitively high sum. A belt sander for regular use or for professional use costs a double about a hand-held model: 150 euros and up depending on the equipment. Stationary professional devices with corresponding performance are around 400 euros or higher.

What does the scope of delivery include?

Depending on the provider and model , the scope of delivery is either limited to standard applications or can be expanded. Ideally, a German-language manual is included so that you can start immediately. This way you can familiarize yourself with the start-up without any guesswork. Well-known manufacturers provide a warranty on certain drive components in addition to the statutory warranty, or the customer can purchase an extended warranty period on request. It is worth comparing the leading brands here.

The weight and the operation of the machine only really matter in practice. A grinder with a small grinding surface for working on narrower workpieces can weigh a kilo, making finer movements more fluid. Large areas can take more pressure and a heavy device is an advantage.

A quick clamping device for the sanding belt saves time when changing. There are also differences in the device design. Mobile devices with a second handle are easier to operate than a one-handed operation with a knob. In the case of a stationary grinder, all fixings and small parts such as screws or table clamps should be completely available. Prefer a model with practical extensions that ensure precise machining of the workpieces

  • A sanding frame prevents the device from tilting, which creates deep grooves in the surface. The frame enables a flat guidance and the adjustment of a grinding depth. A better support does not allow the grinding surface to tip over edges.
  • A rip fence is a guide for reproducible workpieces.
  • An angle stop enables diagonal grinding of edges with adjustable inclination.
  • A graphite sanding plate is mounted between the sanding machine and sanding belt. The material dissipates the tension built up by friction via the grinding machine.
  • A base is an attachment with support and screw clamps that modifies a mobile device for stationary use on the workbench.
  • A suction device with a collection bag keeps the work area clean and prevents dust particles from being released into the ambient air. Connections for external suction are optionally available.

To begin with, sanding belts of various grits should be included. This gives you an example of which dimensions or tapes from other manufacturers fit on the device. Not all types of paper are compatible with all manufacturers. Ultimately, high-quality sandpaper is cheaper than a simple grade that tears or grinds after a short time. If you have decided on a cordless grinder, the charging time should be taken into account. Some manufacturers include the required batteries if the battery is not permanently installed. A sturdy case for storage and transport holds all accessories and protects the belt sander from damage caused by falling and moisture.

What performance should the belt sander have?

You want to process large areas quickly. Choose a version with at least 650 watts to 800 watts of power for a grinder for home use. The drive thus offers sufficient power reserves, which increases the service life of the engine. Daily, hour-long use requires a belt sander with around 900 watts of power in order to withstand permanent wear and tear.

Care and maintenance of the belt sander

Since belt grinders produce a lot of dust, we recommend mechanical cleaning as the last action before every evening. Deposits can best be blown off with compressed air from fine cracks and openings. Alternatively, a brush is suitable for cleaning the belt sander. Stains from paint or similar sticky substances should be removed from the housing immediately. The operating heat liquefies the stain on its underside, which can cause the mass to penetrate inside the machine and cause damage to the drive.

The maintenance of the belt sander is not complex. Like every machine, it requires a little oil that, depending on the design, is supplied either through a line oiler or a fog oiler. Check the storage container and fill it up if necessary. If this technique is not available, add the oil manually at certain lubrication points – follow the manufacturer’s instructions in the instructions. If the belt sander is used for a longer period of time, you should also oil it in between, as with the first operation after a long storage period.

If, despite proper use, malfunctions occur, please send the proof of purchase to a specialist dealer in order to check warranty claims or have a repair carried out.

Top 5 belt sander brands

Which brand should it be? You ask yourself this question if you are looking for a high-quality belt sander and would like to opt for a branded device from a well-known manufacturer. Makita clearly leads the market among commercial buyers, with Bosch and AEG and Festool following closely behind.

The manufacturer Skil has also established itself in the belt sander area and is preferred above all if a cheap device with high-quality performance is to be selected. In our tests, the top brands of belt grinders performed convincingly and not only asserted themselves in their performance and results, but also in customer service, packaging, and the need for spare parts.

These are all factors that should be taken into account when making a purchase decision and which will come into focus when you want complete satisfaction and want to avoid any compromise. Both at Makita, as well as at Festool and Bosch, the devices are of a robust quality and can be designed with various accessories and can be selected to meet the needs in commercial use as well as in home improvement.

Choosing a top brand doesn’t mean you automatically choose a very expensive device. Because both with well-known manufacturers of the brands listed above, as well as with other manufacturers for belt grinders, the product range offers a broad portfolio in different price categories.

Are Lidl belt grinders from Einhell?

In addition to the best belt grinders from our test, there are always discounter offers for belt grinders from brands such as Parkside or Workzone. Now many are asking the question: Are the devices from the discounter equivalent?

There is always discussion in forums and on Amazon whether the brands are not even identical to branded products. For example, there is a stand belt sander from Einhell and a stand belt sander from Parkside which – you can see it in the pictures – do not differ from one another except for the color. Unfortunately, Parkside does not provide product details, so that neither volt specification, weight or anything else could be compared.

It is known that many brand manufacturers sell their products under a different name in the discounter and by addressing different target groups , one simply speculates that nobody will notice. Of course, this is becoming increasingly difficult in the online age.

Brand manufacturers also produce cheap products for the less affluent target group or countries under their own name . These also save on materials. This means that the product is not only cheaper but actually worse.

In our experience with the evaluation of power tool tests such as cordless drills, hedge trimmers or belt grinders from practice testers such as Stiftung Warentest, Ökotest, Konsument or Which ? and the analysis of customer reviews and YouTube reviews, we can say: No, belt grinders and other power tools from discounters are not of the same quality as branded products from Bosch or Makita.

Customers who report positive about discounter belt grinders always do this with the reservation: “for the price”. So a belt sander is extremely loud, vibrates and it is difficult to buy suitable sanding belts, but “for the price” you should “not complain”. Well, according to the company policy of ExpertsTesten.de, we don’t see it as our job to make products bad, we recommend only the best. We haven’t had the parkside or workzone yet.

The illustrated belt sander from Parkside costs 79.99 euros on Amazon. The stand belt sander from Einhell costs 39.96 (from Einhell itself as a seller).

You should pay attention to these criteria when buying

A belt sander can make it much easier to sand or roughen wall surfaces, remove old paint or glue from the wallpaper. The once tedious sanding with a hand sander or sandpaper stretched on a wood is no longer necessary.

In addition to the higher working speed that electrically operated grinding machines display, the associated increase in comfort is also a big plus. At the same time, the integrated dust extraction system reduces the number of dust particles in the air, which is easy on your lungs and therefore on your own health.

However, a belt sander is not the same as a belt sander. In our comparison, there were big differences between the devices, both in terms of performance and ease of use. Therefore, you should inform yourself thoroughly before buying and compare several machines to prevent a wrong purchase. You should pay attention to these comparison criteria when buying an automatic belt sander:

  • High belt speed: this provides the necessary “power” so that the wall or floor can be sanded without great effort and muscle
  • Ergonomic fit: the product ergonomics not only ensure a good grip but also prevent accidental slipping of the device. In addition, a suitable fit counteracts the signs of fatigue after prolonged use and thus relieves the operator. This criterion is absolutely crucial for a relaxed sanding process, especially when sanding large areas
  • Automatic belt centering : as soon as the sanding belt slips off the grinder, an annoying forced break is announced. The belt must be correctly adjusted and adjusted again before you can continue working. This not only costs time but also nerves …
  • Integrated dust extraction: wherever there is planing, chips fall, and wherever there is sanding, the dust flies. Thanks to the modern extraction technology used in the Skil 1210 AA, for example, this does not have to be the case. Suction in connection with a dust bag does not completely capture the dust in all belt sanders tested, but at least ensures a reduction in dust pollution.
  • Easy change of sanding belt: complicated is out! This also applies to different tools. Regardless of whether it is a chopper, lawn trimmer, chop saw or belt sander: wear parts should be easily accessible and easy to replace. Belt grinders with an intuitive belt changing system are therefore more popular than ever!

Top grinding performance vs. “Serrated edge

In the course of the expert tests, completely different comparison results were shown for the different devices. From the flagship device, such as the comparison test winner F0151215AA from Skill, which shines with excellent grinding performance and convenient operation, to grinding machines, which at most have delivered average results in tests.

In addition to the handling, the quality of the ground surface was decisive. Unfortunately, some models failed here. Slightly improperly adjusted treads do not transform the wall into a smooth plane as desired, but leave a wavy profile with dents and cut-like depressions. Due to the different pressure distribution on the pressure plate, flat grinding is sometimes not possible. This not only ruins the wall, the floor, or the wood, but also the nerves!

To avoid this undulating surface and to achieve an optimal finish, we recommend using the comparison winner. This experience coincides with the numerous customer testimonials on Amazon, for example with the belt sander RT-BS 75, whereby the reviews made here show an enormous discrepancy and may be questionable.

Our belt sander comparison helps you to find the right belt sander – 100% independent.

Alternatives to the belt sander

It doesn’t necessarily have to be a belt sander. For some grinding work, for example, a triangular grinder, or also an angle grinder , an orbital sander or an eccentric grinder can convince with a simpler use and a better result. The belt sander is a device for predominantly large areas so that you can optimally machine floors or walls, but also large-area metal surfaces.

To get into small corners and achieve a precise result here, a triangular grinder is well suited. This is not suitable for large areas at all, but should only be used for small-area grinding work, such as on furniture. An orbital sander can replace the grinder for occasional use.

Here, the grinding surface is usually rectangular, provided you choose a classic model. The grinding area is not much smaller than that of a belt sander, but the device itself is more manageable and usually not that heavy. An orbital sander is only suitable to a limited extent for long-term use or large areas because you hold it directly in your hand and the motor generates the circular movement for abrasion.

In some cases, orbital grinders are provided with such a strong rotation that your hand hurts after a short use or reacts with irritation due to the rotating movements. A good decision for infrequent use, but for large areas or in daily use the orbital sander is not an alternative to the belt sander.

The eccentric sander is also an alternative to the belt sander and works via the rotation of the disc, which moves in a circle and carries out both rotary and oscillatory movements.

All-electric grinders can be regarded as good alternatives to belt grinders if you use them when buying and choose the appropriate grinder for your requirements.
