How To Use An Angle Grinder
Which accessories can you use
The versatility that characterizes the angle grinders is because you can adapt a good number of accessories that allow you to perform various tasks with the same tool by merely exchanging the discs according to your needs.
The discs that you can put are the cutting ones that you can use to section sheets, beams, and any other similar material. With diamond wheel discs, you can refine materials such as concrete and stone. Abrasive and sandpaper disks will help you remove debris from the surfaces. With the sheet ones, you can do a similar job since they sand and smooth surfaces quickly, and with the polishing discs, you can polish them. There is a disk for each specific task you are going to perform.
Cut or grind
To perform cutting or grinding work, you must start using the appropriate disc for this in the angle grinder. In this case, it would be the cutting disc. Next, you must ensure that the material you are going to section is stable, that it does not move.
For this type of work, the idea is that you use a workbench to help you firmly hold what you are going to cut. Turn on the grinder making sure you keep it securely. Approach it to what you are going to cut. Brush the surface with the disc and press gently while cutting.
Sharpen the blades
When the blades you use in your home lose their edge, their practicality goes away with them. With an angle grinder, you can quickly return the side. To do this, put the blade in a press or in a clamping system that keeps it very safe. Put the disc to sharpen and turn on the machine. Then, carefully pass the drive-by, gently brushing the blade edge 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 you must use it following all the appropriate security measures.
In principle, preferably, when you are using it, there should be no one closer unless you require the help of another person. In that case, both should be careful when the grinder is on. You should also use some safety implements such as lenses to prevent metal residues from entering your eyes, mask, gloves, and safety boots. The clothes you work with should not be loose. When you are not using the grinder, disconnect it from the electrical outlet and put the protector on the discs.

Buying Guide OF The Best Variable Speed Angle Grinder
An angle grinder is a versatile tool, which makes all types of cutting, sanding, or devastating work of any kind of materials more accessible. For you to equip yourself properly, follow the advice of our guide to buying the best variable speed angle grinder, with which you will find quality models that give that touch that you are looking for in all your DIY work.
When choosing an angle grinder, the operating power is one of the elements that we must take into account to avoid falling short when performing any work. A skill that, as we will see when talking about the disc, it is necessary to adapt to the tasks that we are going to perform, so that the product has the sufficient capacity to deliver them efficiently.
If we take a look at any comparison of angle grinders on the market, we can see how the powers are usually around 700 watts, within the general models with 115 mm disc. This power is sufficient to generate a rotation level of about 11,000 revolutions per minute, with which to move the drive and obtain adequate performance when working properly. Anyway, as with the power, this speed has small variations in the maximum idle rotation that can be achieved with the product.
Conveniently, this speed can be adjusted easily since not all materials or tasks require the same power. If we talk about more fragile materials or more precise works, the speed must be adjusted downwards, to avoid their deterioration during work. That is why it is worth assessing the speed control system, which should have as much versatility as possible.
If the operating power of the product is essential, so is the disc that moves through the engine. Depending on the type of work you are going to do, you must use another drive, also have different sizes and thicknesses, which also fit these jobs. You should know that, if the grinder mounts a large disk, you can mount smaller discs, but not vice versa.
Specifically, the most common grinders are usually 115mm in diameter, being practical and lightweight for small jobs. Discs that are effective cutting and roughing material, although its 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 us 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 how discs are changed. A task that must be simple, so that it is not required to pull many tools or spend too much time in the process of change. A fundamental issue to avoid inconveniences during the process and also maintain proper safety in the work process, which should even be above how much the grinder costs.
Comfort and safety
To finalize our advice to find an excellent and economical angle grinder, we will review both the convenience of use of the product and the security 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 commenting on.
On the comfort side, you should take a look at the handles or fasteners of the product. In general, these models have a main holding handle next to a secondary stem, which allows them to maintain the position of the cutting area and helps to control the process better. If, besides, the product has improvements such as a vibration reduction system or similar, everything is easier to use.
As for the safety of the product, the product must include a protective shield that prevents the possible remains of sanding or cutting from jumping on our faces. In this security, there must also be a mechanism that automatically stops the operation of the disk in case of problems, to avoid risk when working for the service of the drive without complications.
