What Is an Angle Grinder?

For under 20 bucks, you can get this versatile tool that is used in every auto repair shop, workshop, and construction site. 

Like any other tool, it comes in a wide variety of sizes and motor powers. The invention of this tool is debatable. One story is that it was invented in 1954 by a German company named Ackermann + Schmitt. Another story says that Thomas Joseph invented the angle grinder in 1973. Here is all the information you need to know about this relatively new tool. 

Numerous Uses of Angle Grinders

What makes this tool special, is that it’s a wild card in your toolbox arsenal. However, depending on how you are going to use it, you should pick either the corded or cordless version. More about that later but for now let’s focus on explaining the uses of this tool. 

Cutting Tile, Stone, or Even Concrete

You must already be amazed by how strong the wheel is. The dry-cut diamond wheel, which is super thin, provides a more accurate and sharp cut. So don’t worry you can cut almost anything in any shape you would like.

Speaking of concrete, a hard task that no other tool would help you with is removing mortar from bricks. Apply the thicker tuck-pointing wheels and you are good to go. Nothing removes old mortar faster than the angle grinder. Don’t worry about harming the bricks, apply the right pressure and you will get the job done in no time. 

Polishing and Sharpening 

The grinding wheel can be used for restoring edges on your tools. If any of your rougher tools like shovels, hoes, and ice scrapers got damaged, you can easily fix them using the angle grinder.

Remember not to overheat the metal that you are polishing. Apply light pressure and keep the grinding wheel running. A safety precaution would be to have a bucket of water and drench your tool frequently. 

Safety Precautions

There are a lot of risks in using the angle grinder. All the following precautions are to be taken seriously, especially for beginners, and even if you were a professional user, you should keep in mind that safety first. 

  • Always protect your eyes and hands.
  • Always unplug or shut off the grinder when done.
  • Secure the workpiece at all times.
  • Beware of sparks catching on anything combustible in your workspace.
  • Protect yourself from flying debris with a proper protective outfit.
  • Refer to the angle grinder’s user manual before the operation.

How To Get The Right One?

The angle grinder is a basic component in any toolbox. However, if you failed to get the right wheel for your project, you might end up with some disappointing results and you might also damage the wheel itself. 

At first, you should decide whether to get a corded or cordless one. Cordless grinders run on battery, which means they are convenient and easy to use. They are also mobile, so you can take them to remote areas or newly constructed homes. Just remember to charge up the batteries and you are good to go. 

On the other hand, corded models are generally more powerful than cordless ones. They are also lighter in weight, so it won’t fatigue you as fast as the cordless model. 

There are a lot of attachments that can be applied to this tool. Make sure to check them out if you are going to perform an unusual task. 

You should already know why you are getting this tool, so getting the right wheels and the right attachments will save you a lot of money and effort.

That’s why I developed the habit of doing everything on my own. And since this is the only way to reach the unique results I really want, I don’t like depending on any services.
