Angle grinders are a variant of the mill family. These are essential tools that are used in many factories. Notably, technicians always make use of an angle grinder since it’s a reliable polishing machine for metal.

One of the great things about this blender is that it’s hand-held and easy to use. If you handle a lot of projects involving metal, an angle grinder will be a big help. With that said, these angle grinder reviews should help jump start your search!

How Does an Angle Grinder Work?

Angle grinders are also called as a side or disc grinders. These portable tools get these names because it makes use of a rotating disc for grinding and polishing. This rotating disc coupled with its hand-held casing allows you to angle it to the side and polish flat surfaces.

Most angle grinders are powered by electric motors. However, there are also angle grinders that make use of petroleum and compressed air. The body of the grinder starts first with a cylindrical design.

The cylindrical body then is attached to either cutting or abrasive disc. You can choose which to mount to accomplish a particular task. For an abrasive disc, it’s usually meant for grinding. This is what you’ll need if you’re looking to smoothen a surface.

On the other hand, these grinders can also effectively work as cutting tools. When operating, some angle grinders have a second handle. This is usually located perpendicular to the mounted disc. Hence, it gives you more stability and mobility in using it.

Uses of an Angle Grinder

The versatility of an angle grinder is right at the top of handheld tools. These grinders are present in almost any industrial workshop, and that’s because of its wide range of uses.

Using Angle Grinders for Polishing

Angle grinders can be associated with buffers. You have an option to attach a polishing disk to your grinder, which works similarly as a car buffer. Car buffers are usually circular power tools that are used for auto detailing. It polishes your car’s paint to make it shinier.

Moreover, it can remove scratches and other light stains in your vehicle. The same can be applied with your metal works through a grinder. All you need is to get yourself a polishing disk and polishing pads suitable for the type of metal you’re handling. Your local shop should help you with this.

These grinders are best used to finish off your project. Typically, it works well with plexiglass, brass, and steel.

Angle Grinders for Sanding

Another neat trick is to use angle grinders for your woodwork. Back in the day, sandpaper was heavily used to smoothen a piece of woodwork manually. Just imagine the amount of work that puts in your arms and hands. However, nowadays you won’t need to rely on a piece of sandpaper anymore.

Using an angle grinder, you can attach a sanding disk and efficiently smoothen your woodwork. This would eliminate all the dust, loose ends, and even your mistakes upon sawing. Just be sure to wear a face mask and workshop goggles. All that sand dust will harm you if you’re unprotected.

Angle Grinders for Cutting

Cutting with an angle grinder can be tricky at first. These grinders are just a cutting disc away from slicing through metal and wood. However, its hand-held design makes cutting quite unstable as it is. Although cutting rods and scoring tiles are easy, slicing through sheets of metal can be hard.With that said, a bench cutter machine is still a lot more efficient and secure. It’s like comparing a hand drill to a bench drilling machine.

However, with the help of a little woodwork, you can transform angle grinders to efficient cutting tools, arguably even better than a bench cutter.

To do this, you’ll need to spend a couple of hours making an angle grinder holder. It’s a simple trick where you mount the grinder on a base and angle it to your like by using blocks of wood to keep stable at you desired angle. You can further learn how to do this by checking this video.

Angle Grinders for Grinding and Cleaning

Lastly, the angle grinders can help your smoothen the rough edges of your metal work. My first experience with an angle grinder was using it for a project when I was high school. The goal back then was to create a near-perfect circle amulet using a brass sheet, a hacksaw, and an angle grinder.

The grinders will help you chip off metal easily, and the discs come in different varieties. You can even use the grinders to sharpen your blades.

As for the cleaning part, you can attach a metal brush disc to your angle grinder. This is a disc that mimics the wiry texture of a typical metal brush. So instead of tirelessly using your arms to brush metal scraps off your project, you can speed it up by using this versatile power tool instead.

Other Uses

The versatility of an angle grinder extends way further. Some of the best products can be even used as mining tools to cut through stones like limestone. It’s also ideal for ship and car maintenance considering it’s a great buffer tool for paint.
