Buying Guide - What is the best angle grinder on the market?

An angle grinder is a versatile tool, which makes all kinds of cutting, sanding or ravaging jobs of any type of material easier. For you to equip yourself properly, follow the advice of 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.

which is the best angle grinder
Operating power

When choosing an angle grinder, the operating power is one of the elements that we must take into account to avoid falling short when doing any job. 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 the best angle grinders on the market, we can see how the powers tend to be around 700 watts approximately, within the general models with the 115-millimeter disc. This power is enough to generate a level of rotation of about 11,000 revolutions per minute, with which to properly move the disc and obtain adequate performance when working. In any case, as with power, this speed has small variations in terms of the maximum idle speed 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 precise work, it is important that the speed is adjusted downward, to avoid deterioration of them during work. For this reason, it is worth evaluating the speed control system, which should be as versatile as possible.

Disc Features

If the operating power of the product is important, so is the disc that is driven by the motor. Depending on the type of work you are going to do, 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 vice versa.

Specifically, the most common grinders are usually 115mm in diameter, being practical and light for small jobs. Discs that are effective in cutting and grinding material, although their cutting capacity is around 20 to 30 mm, which means that they lose 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 in which 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 maintain the due security in the work process, which must even be above how much the grinder costs.

Comfort and safety

To finish our tips to find a good and economic angle grinder we will review both the comfort of using the product and the safety it offers us when working. Two fundamental elements in any power tool, but even more 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 clamping handle along with a secondary handle, which allows the position of the cutting area to be maintained 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 key that the product includes a protection shield that prevents the possible remains of the sanding or cutting from jumping on our faces. In this security, there must also be a mechanism that stops the disk from functioning automatically in the event 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 do endless work 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 perform various tasks with the same tool by simply exchanging the discs according to your needs.

The discs that you can put are the cutting ones that you can use to cut sheets, beams, and any other similar material. With diamond grinding wheels you can refine materials such as concrete and stone. Abrasive and sanding discs will help you remove residues adhering to them. With sheet metal, you can do a similar job, as the sand and smooth surfaces easily and with polishing discs, you can polish them. There is a disc for each specific task you are going to do.

Cut or grind

To perform cutting or grinding work you must start with using the appropriate disc for this on 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 hold firmly 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. Rub the disc with the disc 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 bring the edge back. To do this, put the blade in a press or clamping system that keeps it secure. Put the blade to sharpen and turn on the machine. Next, carefully pass the disc gently across the edge of the blade at an angle between 25 and 35 degrees.

Use it safely

An angle grinder is a power 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 for the case.

In principle, preferably, when you are using it, there should be no one nearby, unless you require the help of someone else. In that case, both should be careful when the grinder is on. You should also use some safety equipment such as glasses to prevent metal residues from entering your eyes, face masks, gloves, and safety boots. The clothing 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 discs.
