How to choose your grinder

Indispensable for any self-respecting handyman, the grinder cuts, slices and polishes. How do you choose one that does all three of these functions?

#1 - Type of grinders

According to the arrangement of the rotation axis of the grinder disc, we can distinguish 3 types:

  • The angle grinder where the disc is perpendicular to the motor axis. It is the most common on the market simply because it is the most versatile;
  • The straight grinder, also known as a rod grinder, which is used for finishing work. In the nooks and crannies where the angle grinder can't go, the straight version takes over;
  • The disc cutter, which is particularly effective for cutting concrete, steel, stone, etc. This tool also called disc cutter, thermal cutter or groover, is used by firefighters to cut a car during accidents.

#2 - How it works

It refers to the power supply mode of the grinders; a criterion that affects the use of the device.

  • The electric grinder is the most common on the market. It can be corded or cordless, and has a power between 500 and 2500 W.
  • The pneumatic grinder is equipped with a compressed air hose. It is certainly powerful, but it is difficult to handle because of the size of the hose.
  • The thermal grinder is attractive because of its exceptional power. It is easy to see why it is used for large jobs.

#3 - Power and usage

Depending on the task to be done, you must choose the size of the disc and the power of the grinder.

  • If you do small jobs on a regular basis, a power of about 1200 W for a 125 mm disc is more than enough.
  • For occasional small jobs, a motor of 750 W and a blade between 115 and 125 mm is sufficient.
  • For large jobs, you need at least a 230 mm disc; the power can vary between 2000 and 2500 W depending on whether you use it occasionally or frequently.

#4 - The standard

Compliance with CE safety standards is necessary to ensure that the grinder has been manufactured to the highest standards. However, this is not sufficient to rule on whether or not it is safe to use. Indeed, the existence of a good insulation and a cooling system is necessary to prevent the device from overheating with the rotations of the disc.

#5 - Ergonomics

Whether you are a professional or a do-it-yourselfer, you will have to invest in a light and ergonomic grinder to avoid getting tired from the first minutes of use. In general, grinders have an ergonomic handle that makes it easier to hold. As for the weight, remember to check it before buying.

How to use a grinder?

A versatile tool, the grinder is not only used to grind, it can be used to remove rust from metal tools, or to cut cinder blocks. Equipped with a metal disc, it can cut iron, aluminum, etc. Diamond discs can even be used on extremely hard materials like marble.

It is important to know how to use it properly and to follow some safety rules because it can be dangerous. You must therefore read the instructions for your tool carefully to avoid the risk of serious injury. First, you need to equip it with the disc you need. Make sure your device is unplugged before placing your disc. Then tighten the disc depending on the grinder model.

Once started, hold your grinder vigorously. Allow the disc to spin for a few seconds, then start with small rocking motions so it doesn't heat up. When you're done, don't put the grinder down until the disc is still.

So there are a few precautions to take when using the grinder. Before plugging in your tool, you need to make sure that your cord is not damaged as this can present an electrical shock hazard. Also, make sure the disc is securely attached before turning it on. Always unplug your grinder before making a change of consumables.

The most important thing to remember when using a grinder is to watch out for flying sparks. So, make sure you are not in an area with flammable materials. In addition, you need to protect yourself by wearing tightly closed goggles, thick gloves, a dust mask and hearing protection. Don't forget to replace the protective cover when you have fitted your tool with a new disc.

Portable grinder or circular saw?


Designed to cut, grind, deburr, chamfer, cut-off, surface, strip or polish, the grinder has unmatched versatility. It can be used for domestic work such as cutting tiles or blocks, polishing wood, removing rust from a gate, etc., as well as for professional work. The grinder offers good maneuverability, although this depends on its size.

This machine can even be easily handled by inexperienced people. It has safety options to reduce the risk of accidents and injuries. Among other things, there is a clutch control in case its disc gets stuck. However, the grinder is still dangerous. You must be careful when you decide to use it. For example, wear gloves and goggles.

Portable circular saw

The portable circular saw falls into the category of portable electric saws. This tool cuts different kinds of materials thanks to its sharpened serrated disc that rotates at a very fast speed (up to 6,000 rpm).

The main strength of a portable electric saw is the depth of its cut. It can cut very thick materials. Equipped with a guide rail, it also provides a good straight cut with surgical precision. On the other hand, it offers less versatility than the grinder.


A portable circular saw can be a great tool, but its efficiency and adaptability are limited. A better choice is a grinder, which is capable of cutting through most of the materials you might encounter on a job site. It is a better choice for doing various jobs with one tool.

Why buy a grinder?

For easy cutting of hard surfaces

With a diamond wheel, a grinder is very useful for cutting stone without problems. With the help of this tool, you will also obtain a very precise cut. With it, you also have the possibility to deburr tiles. For example, you can cut a large stone if you have a diamond wheel. Ceramics are also materials that you can process with a grinder in order to obtain tiles. But it is not only that, because being a very practical tool, a grinder can cut concrete and marble.

To cut different metals

Using a grinder, you can cut various metals. To do this, you only need to use rigid discs. This way, you can cut aluminum, sheet metal or tubes very quickly.

To ensure a nice finish

A grinder is very practical for polishing operations. All you have to do is fit it with a flap disc. Whether it's for industrial or artistic work, you'll have a flawless finish. This tool is capable of smoothing any flat surface according to your expectations and also according to the finish you want to have. On the other hand, a grinder is a multifunctional tool that allows you to do sanding work. In this case, you must have the necessary accessories such as soft or rigid discs.

To strip metals

The stripping of metals will be for you a child's play thanks to the grinder. You can therefore use metal brushes to remove rust and any trace of paint. As a result, you will have a smooth metal surface free of rust.

For successful sanding

The grinder is a multi-purpose tool. You can use it to sand many surfaces. You just need to equip it with the right sanding disc for your needs.

Be careful.

Make sure the object you are working on is secure. The speed of rotation of the grinder can easily dislodge or even throw the workpiece you are working on.

Use the right tool.

Grinding discs are consumables; the grinding wheel itself is not. Be sure to use the appropriate grinder that can handle adequate amperage for the job.

Pay attention to your working angle.

Generally, grinders are designed to be used at a working angle of 5 to 10 degrees from horizontal, and the wear pattern on the face circumference of the disc should be about twice the thickness of the disc


Wait a while before using the grinder.


't start the grinder while it's resting on your worktable or the workpiece you want to work on. The grinder may bounce off the table or workpiece.

Look at the spark.


sparks produced by your grinder can tell you how you are using your machine. Your grinder should produce sparks that should wait for distances of about 3 to 4 feet from the workpiece, evenly. This shows that the grit on the grinder is doing what it is supposed to do. If you push too hard or don't push hard enough, the sparks won't be as intense.
