Rank # 4: BLACK+DECKER Angle Grinder
Some craftsmen want more flexibility at the work table, and a power supply could be an impediment to their work, for two reasons: first, it confuses the space and second, it limits the range.
Therefore, we recommend to these craftsmen an angle grinder with battery, ie this model, which includes an angle grinder adapter for the socket.
It is loaded, therefore, on the network, operates a 125 millimeter disc (with a cutting depth of 33 millimeters!).
,And the manufacturer recommends working on metal.
The maximum speed reached is 8500 revolutions per minute (this being the main disadvantage of the model, because for such small discs many models offer over 10000 RPM).
Its battery is detachable and can be used with other tools in the Einhell range.
Overall, the device here can be taken and used anywhere, but not for long, as you will have to recharge it frequently.
Rank # 5: CRAFTSMAN Small Angle Grinder
The range of professional products also includes this Hitachi angle grinder, given its 2000 Watt motor which operates discs 23 centimeters in diameter with speeds of up to 6600 rotations per minute.
The construction of the device is designed for long use, but also for high comfort – the handle is made to reduce vibrations, and the entire structure is balanced for more control.
The motor system and bearings are designed to be protected from dust, and the guard has an adjustable position.
Overall, this grinder copes with office and demanding work needs, such as cutting metals and polishing hard surfaces of all kinds, although the manufacturer recommends it for steel, aluminum and iron.
The big disadvantage of this 230mm angle grinder, it is sold at considerably higher amounts even than the prices of other professional models.
Rank # 6: Dewalt DCG412B 20V grinder
With 12,000 revolutions per minute of maximum speed, the model here, a Skil angle grinder.
It will efficiently use very small discs, 115 millimeters in diameter, for grinding and cutting on materials of all kinds (universal use).
However, it is a device for hobby needs, ie short-term, its 600 Watt motor running periodically and needing a cooling break.
The big plus of the device is the fact that in the package you also receive a hex key and flanges, useful when you want to equip your workshop and you don’t have much in it.
Includes shaft locking system, adjustable handle, anti-restart function, and its weight is only 1600 grams.
Moreover, it is also very affordable, and as a disadvantage, it does not cope with a demanding work regime.
Rank # 7: Milwaukee 2680-20 M18 18V Lithium Ion Grinder
It includes, in our range of products, a grinding disc, ie an accessory for the tools we have presented so far.
It has a diameter of 100 millimeters, and its special surface, with serrated teeth fixed in screws, makes it suitable for wood carving, both soft and hard essence, for sectioning, making channels and other operations.
Of course, it can also be used on large soft materials, such as plastic or PVC.
The optimum speed recommended by the manufacturer is between 10,000 and 13,000 rotations per minute, and the chain has 14 teeth.
The teeth can be sharpened, and if they touch a nail in the wood from which you are sculpting, then the chain will lock, allowing the disc to rotate, which means that the risk of accidents will remain minimal.
This angled wood cutting disc is suitable only with small tools, for 115 mm discs, with a grip hole 14 mm in diameter.
For grinding, cutting and leveling, or for other adjustment tasks, an angle grinder is the tool you will need.
Regardless of whether you are looking for large, heavy-duty or small models for hobbyists, there are a number of principles on which to choose these power tools.
We list them below, discussing them in general terms and guiding ourselves according to opinions about the best angle grinders, both on forums and from expert craftsmen:
As in the case of many other tools of arrangement, repair and construction, we can separate the products into three categories: hobby, semi-professional and professional.
If you opt for an angle grinder, at a good price, for light and occasional work, ie hobby , then the device will have weak motors (less than 750 watts) and will be compatible with small discs (less than 15 centimeters in diameter).
Professional models have high power (even over 2000 watts), can accommodate even large disks, but also multiple functions, for all kinds of different tasks.
In general, semi-professional models fall into these two categories, although there is no clear definition of their strengths and other performance elements.
influences two aspects: grinding power and speed. If you have opted for a 125 mm angle grinder model, then the disc of that diameter will be able to generate more power on a weaker motor.
On the other hand, on models with large diameter discs, the motor will be more powerful, otherwise, due to the lever effect generated by the diameter, the disc may slow down or stop during use.
It is not surprising, therefore, that professional models will either be compatible with several disk sizes, or will be of the angle grinder type with variable speed, ie with a system that will allow the adjustment of the rotation speed of the disc, for all kinds of different tasks.
The power of the motor determines the efficiency of the device, in tandem with the diameter of the disc, but also with the speed. For some tasks, you may want higher speeds (such as metal polishing), and for others, higher power, but lower speeds (say you cut pieces of wood).
An angle grinder, at a good price, should not leave much to be desired in this regard, but for heavy tasks, you should invest in a high-power model. As I said above, the electric motors that equip these tools range from under 700 watts to over 2,000 watts.
Maximum rotational speed: also in connection with the efficiency of the devices, we can also discuss the rotational speed. Theoretically, a grinding wheel should have, at its edge, a speed of about 200 kilometers per hour. This means that smaller discs will need high speeds, and larger discs will reconcile well with low speeds.
To provide figures, for discs between 115 and 125 millimeters, we will need about 10-12,000 rotations per minute, for those from 150 and 180 millimeters, between 7 and 8,000 rotations, and for those of 230 millimeters, about 6 -6,500 RPM.
You can choose a cheap and good angle grinder model that supports discs of various sizes, but if you equip it with a small disc and you do not have the option to increase the speed, its efficiency will be considerably reduced.
Recommended surfaces : each model you can find on the market will have specified the range of surfaces for which it is recommended. The best grinders are universal, ie for any material, wood, metal, stone. Others are more niche, recommended only for one or two types of surface.
The type of disc also matters on certain surfaces. There are some diamonds, for stone and metal, others with aluminum oxide, for wood, or silicone carbide, for cleaning metal. Brush discs are used to remove paint and rust.
Cutting depth :
If you have chosen a device of this type, it is good to know the cutting depth, ie how much the rotating disk can enter the surface of a material.
As some of you expected, this depth depends on the diameter of the disk, but also on the power of the engine. Thus, for 115 mm discs, it will usually be 5 millimeters, and for large discs (over 230 millimeters), it could reach up to 30 millimeters.
It is worth taking into account the accessories received in the package: discs of various sizes, socket adapters, if you have opted for an angle grinder with battery, or tightening brackets, or even protective gloves or splint wrench.
You can also find packages with angular grinding support, very attractive if you do not yet have a place to store it in sight, in the workshop.
It is good to find out as much as possible about these tools, if you have decided to buy something like this. For this reason, for anyone who wants to get their first Bosch, Makita, Stern or Einhell angle grinder, we also offer the sections below, one with frequently asked questions and the second (very important!) With safety measures, when using sea tools.power:
Can I find spare parts for Einhell or Stern angle grinder online?
Of course, nowadays you can easily find parts for an Einhell or Stern angle grinder. We can recommend both the official sites of the respective brands – do not hesitate to contact them directly, by e-mail, if you have questions about where to find the respective parts.
We can also suggest you to use used sales platforms. There you can find all kinds of parts, but also whole grinders – the defective ones can be bought for spare parts, but be careful to take some that have not been worn too much!
Are there Bosch angle grinder models with variable speed?
Of course. You can find angle grinders, at good prices, from this manufacturer, which also offers this sought-after function. The German company Bosch is not in vain in the top of the companies that produce tools for workshops and constructions. Explore his offer in detail and you will surely find what you need!
Where do I buy an angle grinder holder?
If you are the type of person looking to check the desired piece on the spot (ie at the store, before buying it), then we will recommend you go to large retailers, with large warehouses, where you can also ask the opinion of some representatives.
You can, of course, order a support from the sites that sell something like this, but here there is a risk that it will not match some models of angle grinders.
What are the most important angle grinder accessories?
We can mention a large range of discs: grinding, polishing and cutting, in diameters compatible with the device. In addition, you will need to take safety precautions , through accessories such as protective gloves or special goggles, which protect your eyes from splinters or sparks that may result from using the respective tools. More information on safe work is included in the following section of our guide:
Safety rules when using the angle grinder
Whether you use the best angle grinder on the market or budget models, safety must come first when operating such high-powered tools. Considering the speeds of the discs, but also the mains voltage at which it operates, some norms of safe use of the respective equipment are imposed. We explain them in the following lines and we urge you to respect them with holiness:
Equipment needed for safe use of tools
If you have a battery-powered angle grinder, then you won’t have to worry about the length of the power cords, but most models are powered directly from the outlet. We can therefore say that it is important to use quality extension cords, which prevent sparks and short circuits, therefore invest some money in such a thing.
Other essential elements, when operating with devices of this type, are protective gloves and goggles. The gloves not only protect the hands from splinters and blows, or from abrasion if you accidentally touch the rotating disc, but also allow the firm handling of the device, as they usually have rubber surfaces on the palm side.
As for the glasses, they have the role of preventing the penetration of chips or sparks in the user’s eyes. If you have eyeglasses, look for a larger viewfinder that comes over them, similar to welding masks, but without smoky glass. If you work with materials that generate dust or particles that can be inhaled, you will also need to wear a mask for the nose and mouth to prevent them from entering the airways.
Tips for using discs
Do not use other types of discs than those indicated in the product user manual! For example, if you have an angle grinder that does not specify compatibility with smaller discs, then it is best to avoid them.
In addition, pay attention to the protective guard for the disc – it has the role of preventing the part from being touched for cutting and polishing, so grab the tool so that, in the event that your hand escapes, you touch the guard and not the disc.
If you are not an experienced craftsman, properly document how each type of disc is used (depending on the material) and do not try to use, for example, a metal grinding disc to cut wood, and so on. far away.
What do we do when there are other people in the workspace?
The best advice, in this situation, is to keep an eye on the other person at all times. Be careful not to trip over him or her, do not throw dust or chips in his face when working, and if there are children in the area, it is best to send them to play elsewhere.
If the little ones are curious to see how you work, equip them with glasses and a mask and make them sit at a safe distance from the work table, where they can clearly see what is happening there.
Tips for storing the grinder
When not using the angle grinder, keep it either in a special wall bracket or in the special storage box that came with it. Don’t forget not to leave it in the socket and not to leave it somewhere where children could play with it! This tool is very powerful, with dangerous parts , therefore it would be best to keep it under lock and key, either in a tool cabinet, or in the shed or workshop!
