Angle grinders come in a variety of sizes, but the most common sizes are 115mm and 230mm. All the grinders in this review are of the smaller size as that is ample for most home and DIY needs. However, if you are cutting large sheet material or slabs then the best angle grinder for you will be a larger machine. You can purchase a variety of discs for your grinder, depending on the task at hand. Just make sure when purchasing that you choose the right size for your tool.

Angle grinders also differ slightly in power. Here’s what to look for when choosing the best angle grinder for you.

Wattage

The power of a tool is measured in watts, and the higher the wattage the more power the tool will have. Larger tools will need a higher wattage to power them than smaller machines.

No-load-speed

The second measurement to take into consideration is the no-load speed. This is the speed at which the disc rotates. The higher this number, the more efficient the grinder will be. Angle grinders usually have quite a high no-load speed as they are heavy duty tools designed to cut hard materials. While 1,200 may be enough in a drill, a load speed of around 10,000 or more is required for a powerful angle grinder.

FAQs

How do you use an angle grinder to cut metal?

An angle grinder is the perfect tool for cutting metal. You will need a metal cut off wheel to complete the job. Never be tempted to use a stone cutting blade to cut metal as this could result in the metal breaking up and bits flying off. Once you have fitted your blade, secure the item you wish to cut and then apply the grinder to the metal with light pressure. The grinder will do the rest.

How do you use an angle grinder to cut tiles?

To cut ceramic tiles, stone or concrete you will need a stone cutting or diamond blade. Diamond blades are quite expensive, but they get the job done and last a while. If you attempt to cut very hard materials with inferior blades you will get poor results and probably ruin the blade. Diamond blades are available in ‘wet’ and ‘dry’ and as the name suggests one type can be used dry while the other needs to be kept wet while in use.

Cutting these materials is the same as cutting metal, however with items such as stone you may have to apply a little more pressure and the cutting will take a lot longer.

How do you use an angle grinder to clean, grind, sand and polish materials?

Angle grinders are ideal for cleaning, polishing and grinding. The secret is to use the right wheel for the job. Cleaning rust and dirt from metal can be done with a wire cup brush or wire wheel. Grinding discs are available for both metal and stone. Abrasive discs and sanding discs are also useful for cleaning up and smoothing work. Flap sanding discs are a particularly useful attachment as they can clean, sand and even grind a little. They are also very long lasting. Flap sanding discs are available in rough and smooth grits which allows you to get a very nice smooth finish. Finally, you can purchase polishing pads for your grinder to polish both metal and stone.

Can you use an angle grinder to sharpen blades?

You can use an angle grinder to roughly sharpen blades. You will need to attach the blade to a secure surface with a clamp and then carefully take the grinder to the edge of the blade to begin sharpening. If the blade you are sharpening begins to get hot, stop and let it cool down otherwise you can damage the blade.

What safety precautions should I take when using an angle grinder?

Angle grinders are fast and powerful tools and should be used with the utmost caution. Always wear a face shield and gloves when using one. In addition, always make sure the guard is properly adjusted for the job you are undertaking.

When using a new wheel, run it for a minute or two in a protected area to make sure it is not faulty or damaged.

Always orient the wheel so that it spins away from sharp edges. This will prevent the wheel from catching and throwing the work or causing the grinder to kickback.
