Buying Guide – What is the best angle grinder on the market?
The angle grinder is a versatile tool, which makes all kinds of cutting, sanding or devastating jobs of any kind of materials easier. To equip yourself properly, follow the advice in our guide to buying the best angle grinder, with which you will find quality models that give it that touch you are looking for in all your DIY jobs.
When choosing an angle grinder, the operating power is one of the elements that we must take into account to avoid falling short when carrying out any work. A power that, as we will see when talking about the disc, it is necessary to adapt to the tasks that we are going to carry out, so that the product has sufficient capacity to perform them efficiently.
If we take a look at any comparison of angle grinders on the market, we can see how the powers tend to be around 700 watts approximately, within the general models with a 115-millimeter disc. This power is enough to generate a level of rotation of about 11,000 revolutions per minute, with which to move the disc properly and obtain adequate performance when working. However, as with power, this speed has small variations in terms of the maximum idle rotation that can be achieved with the product.
It is convenient that this speed can be adjusted easily, since not all materials or tasks require the same power. If we are talking about more fragile materials or more precision work, it is important that the speed is adjusted downwards, to avoid their deterioration during the work. That is why the speed control system should be evaluated, which should be as versatile as possible.
If the operating power of the product is important, so is the disk that is moved by the motor. Depending on the type of work you are going to carry out, you will have to use another disc, also having different measurements and thicknesses, which also fit these jobs. You should know that, if the grinder mounts a large disc, you will be able to mount smaller discs, but not the other way around.
Specifically, the most common grinders are usually 115mm in diameter, being practical and light for carrying out small jobs. Discs that are effective in cutting and grinding material, although their cutting capacity is about 20 to 30 mm, which means that it loses efficiency with thick materials. In this case, we can bet on models with 230mm discs. These discs allow you to work with thicker materials and be more efficient when working on large materials.
In addition to the above, it is also necessary to assess the way the discs are changed. A task that must be simple, so that it is not necessary to pull many tools or spend too much time in the change process. A fundamental question to avoid inconveniences during the process and also to maintain due safety in the work process, which must even be above how much the grinder costs.
Comfort and safety
To finish our advice to find a good and economical angle grinder, we will review both the comfort of use of the product, as well as the safety it offers us when working. Two fundamental elements in any power tool, but even more so when it comes to cutting and sanding tools like the ones we are discussing.
On the comfort side, take a look at the handles or fasteners of the product. In general, these models have a main holding handle together with a secondary handle, which allows to maintain the position of the cutting area and helps to better control the process. If, in addition, the product has improvements such as a vibration reduction system or similar, everything is easier to use.
Regarding the safety of the product, it is essential that the product includes a protection shield that prevents possible remains from sanding or cutting from jumping onto our faces. In this security, there must also be a mechanism that stops the operation of the disk automatically in case of problems, to avoid risk when working for a smooth operation of the disk.

How to use an angle grinder
Whether in a specialized workshop or at home, a single tool can perform endless jobs if used properly. Within the market there are numerous tools that stand out for their versatility and practicality such as angle grinders with which you can cut, sand, clean, sharpen and do many other jobs.
What accessories can you use
The versatility that characterizes angle grinders is due to the fact that you can adapt a good number of accessories that allow you to carry out different tasks with the same tool, just by exchanging the discs according to your needs.
The discs that you can put on it are the cutting discs that you can use to section plates, beams and any other similar material. With diamond grinding wheels you can refine materials such as concrete and stone. The abrasive and sandpaper discs will help you remove residues adhering to them from the surfaces. With the sheet ones you can do a similar job, since they sand and smooth surfaces easily and with the polishing discs you can polish them. There is a disk for each specific task that you are going to perform.
Cut or grind
To perform cutting or grinding work you should start with using the appropriate disc for it in the angle grinder. In this case it would be the cutting disc. Next, you must make sure that the material you are going to section is stable, that it does not move.
Ideally, for this type of work, you should use a workbench to help you firmly hold what you are going to cut. Turn on the grinder making sure to hold it firmly. Bring it closer to what you are going to cut. Brush the disc over the surface and press gently as you cut.
Sharpen the blades
When the blades you use in your home lose their edge, their practicality goes with it. With an angle grinder you can easily sharpen it back. To do this, put the blade in a vise or clamping system that will keep it very secure. Put in the sharpening disc and turn on the machine. Then carefully pass the disc by gently brushing the edge of the blade at an angle between 25 and 35 degrees.
Use it safely
An angle grinder is a powerful machine whose motor rotates at high revolutions per second, which is capable of causing damage; especially when you have some kind of disk mounted. That is why it is very important that you use it following all the security measures corresponding to the case.
In principle, preferably, when you are using it there should be no one else nearby, unless you require the help of another person. In that case you both need to be careful when the grinder is turned on. You should also use some safety implements such as glasses to prevent metal residues from entering your eyes, face masks, gloves and safety boots. The clothes you work with should not be baggy. When you are not using the grinder, unplug it from the electrical outlet and put the protector on the blades.

Frequently asked questions
Q1: How to cut wood with an angle grinder?
Cutting wood with a grinder is not an easy process. However, if you want to do it, the right thing to do is wear protective eyewear and a safety mask. There are even those who suggest the use of gloves.
Caution must be exercised in each of the cuts and it is verified that the wood does not have pieces of material inserted, so that the grinder disc does not collide with them or the equipment jams.
Therefore, after using the clothing, the next thing is to adjust the cutting wheel and activate the protection of this in the grinder. When the good condition of the wood has been verified, the grinder should be turned on and the cut that is needed carefully made.
When it is finished, it will have to be turned off and wait a little and then remove the disc. If it is a model with a power cable, then it will be necessary to disconnect it for the user’s safety.
Q2: How to use the angle grinder for sanding?
A grinder is a piece of equipment that can be sanded, but it is necessary to adapt an accessory that is usually a rubber base and, in turn, it should be used with a special sandpaper, in order to have a firm base that prevents that breaks as a result of revolutions. These sandpaper have different textures for professional finishes.
To begin, the piece must be fixed with presses and the grinder must be passed with both hands and the necessary protection, because the action will generate a dust that can end up in the eyes and mouth.
During the passes, there is no need to generate pressure, just hold the grinder safely with both hands on the piece and support it gently, since it will be the disc that will be in charge of polishing.
Q3: How to cut ceramic with an angle grinder?
With grinders, the cuts are usually clean and professional, as they are tools that serve to divide various materials. However, it all depends on the disc that is used. The most recommended in the case of ceramics is to use a double diamond disc. The technique is the same as for wood cuts, as are the safety recommendations. The ceramic or porcelain tile should be on a stable surface and the grinder should be passed in the desired direction for cutting.
Q4: How do you take apart an angle grinder?
Disassembling the mechanical parts of the grinder can be a complex task that could even damage the work equipment, so it is recommended to leave this to the professionals.
However, the head can be disassembled to fit new discs. For this, it is only necessary that the device is disconnected and release the disc lock, and then carefully remove the disc from the holder.
Q5: How to make an angle grinder stand?
Cutting freehand with the angle grinder can lead to the final product not being perfect and not matching the rest of the pieces, so it is convenient to have a support. These pieces can be purchased, but can also be made independently, if you have knowledge in blacksmithing.
This is because it will be necessary to make a metal structure that will support the weight of the angle grinder, so it is necessary to take the measurements of the device, create a sketch and weld the parts until you get a base on which you can rest the equipment, and then place it on a rail on the work table.
