What Can You Do with an Angle Grinder?

An angle grinder is a common power tool used in construction and repairing sites for many applications. Here we will discuss the 6 main applications of this device.

 

Sharpening and Grinding

This is the most common application of an angle grinder. Install a disc in your grinder, and the tool is ready to accomplish cleaning or welding joints tasks. An angle grinder will deliver the best result in eliminating excess material tasks. 

An angle grinder is also eligible in sharpening any even and flat surface, restoring any edge, etc.

To get rid of such a problem, ensure moving the angle grinder through the operation. Or you can use a wet sponge or cloth to drench out the metal repeatedly. 

 

Metal Cutting

Yes, an angle grinder can cut metal; you have to use the right attachment for this. Cutting rods, bolts, or bars can be tiresome work with a hacksaw. In contrast, an angle grinder will give you faster-cutting results compared to a hacksaw.

You can cut sheet metals quite effortlessly by installing a thin, rough cutting metal in an angle grinder. In the construction site, workers use an angle grinder to cut rebars used for strengthening concrete. 

Undoubtedly, these are heavy-duty tasks. With a powerful motor, an angle grinder will deliver brilliant results when handling cutting steel or other likely materials.

 

Tile Cutting

Tile or concrete cutting is an inevitable task of any home improvement or renovations work. But without a dedicated tile saw, cutting tiles can be a painful job. The good news is, with an angle grinder, you can comfortably do this job. Install a dry-cut diamond disc in it and start cutting tiles or concrete.

Masonry Cutting

All you need to do is, install a diamond cutting disc in the angle grinder head, and the tool will take all the responsibility in its shoulder to give you efficient masonry cutting results.

 

Mortar Removing

Are you worrying thinking of which tool to use for removing old mortar from bricks? Without thinking twice, you can shake your hands to an angle grinder.

To remove old mortar entirely, you will require to run the grinding disc over the mortar for multiple times.

Wearing safety gear like goggles, a face shield is mandatory in this task since it creates a lot of dust. Otherwise, serious injury may happen because of the flying dust. 

 

Metal Cleaning and Polishing

A cup brush or wire wheel is an efficient and quick performer in removing rust. Although both attachments are manufactured for specific jobs, such as a cup brush is suitable for removing paint for even and flat surface. In contrast, a wire disc is an ideal option for cleaning metal from hard-to-reach areas.
