What is an angle grinder?

It is a handheld power tool that uses a rapidly whirling abrasive disk to cut through many materials like metal, stone, and concrete. Angle grinders can be used for a wide variety of purposes, and it’s important to choose the right one for your task. Before you buy an angle grinder, make sure you know what size and type of blade you need.

These are multipurpose power tools that can be used for grinding, cutting and polishing. These grinders are available with either a three-jaw or four-jaw design. The former is more expensive but allows a larger range of movement, which means you can use it to cut at different angles and perform other tasks that require greater flexibility.


Why use an angle grinder?

These grinders are powerful tools that can be used for a variety of applications. They’re often used in construction and manufacturing to cut through materials such as metal, stone, and concrete.

But they can also be useful in the home if you need to cut through hard materials.
Angle Grinders can be used for a variety of tasks, including cutting and shaping metal, removing rust, grinding, sanding, and polishing, or using as a sander in woodworking projects. Moreover, if you know how to grind concrete with angle grinder then your working will be convenient with the use of this handy tool.

For any of these applications, you need to know how to choose the best disc for your project and how to attach it correctly so that it won’t fall off and cause injury.

The choice of the disc is based on the size of the angle grinder you are using, how quickly you want to remove material, and whether or not you need a more aggressive cutting action.   In this article, you will look at all these factors to help you to choose the best disc for your project.


How to Choose an Angle Grinder Disc 

A grinder is a handheld tool that uses rotating abrasive discs, wheels, or drums to grind materials. These power tools are used for various applications such as cutting through steel and concrete and polishing stone. Grinders are available in different sizes and power outputs to suit the user’s needs.

The first thing to do when choosing an angle grinder disc is to decide what type of grinding job you will be doing. There are three basic types of discs: metal, wood, and abrasive.

  • Metal cutting discs come in a variety of thicknesses and styles. The type you choose depends on the material you will be cutting, as well as the thickness of the material you are working with.
  • Woodcutting discs come in a range of sizes and tooth designs. These discs are made to cut through wood quickly and easily while leaving a smooth finish behind. Woodcutting discs are designed to cut through wood without creating a lot of dust. This is because they use a large number of small teeth to tear the wood apart instead of using one large blade.
  • Abrasive disc tools are used for various purposes. These are flat, circular pieces of steel or aluminum that have been coated with an abrasive material such as silicon carbide, aluminum oxide, garnet or emery. These discs are used to grind and polish metals and other materials.

An angle grinder, also known as an edge grinder or disk grinder, is a handheld power tool used to grind and polish. The most common type of angle grinder uses an abrasive disc that spins at a very high speed.

  • Abrasive discs are available in different grades to provide the appropriate level of coarseness for the job at hand.

An angle grinder is often used to remove wood from a piece of furniture to make it smaller or create space for another part. This can be done with the use of the edge of the disc, which removes wood quickly, or after using the side of the disc, which leaves a smoother finish.

  • The sanding disc can also be used to smooth out wood that has been sanded with a belt sander.

Grinding and polishing are two of the most common uses for an angle grinder.

How to use an angle grinder

  1. A four-jaw design is cheaper and provides a better grip. The right choice depends on the work you intend to do with your angle grinder.
  2. Hold the angle grinder in one hand, resting it on your other palm so that the motor shaft points up at about a 45-degree angle.
  3. Position the front of the grinder over the sharp and abrasive cutting wheel so that it rests on top of the flange or clamp holding it in place. Push down until you feel the wheel seat into the flange.
  4. Tighten the set screw located in the centre of the wheel using a 1/4″ hex wrench.
  5. Press down on the wheel until it is firmly seated on top of the flange and can no longer be moved side to side or up and down.
  6. With your hand still on top of the grinder, press down on one side of the grinding wheel so that it touches the bottom of the container.
  7. Now turn the grinder over so that the top of the grinder is facing up and place your other hand on top of the grinder, keeping your fingers clear of the grinding wheel.
  8. Turn the grinder on and grind away.

Safety Tips

Safety is of paramount importance when using angle grinders and other power tools. Here are some safety tips to help ensure a safe and productive workday.

  • When choosing an angle grinder, always choose a tool that has a powerful motor.
  • If you are going to be using the grinder for long periods, or if you will be using it to cut metal and other hard materials, choose a model with at least 4 amps.
  • Also, consider getting a tool with an adjustable speed dial. This allows you to change the speed of the tool depending on what material you are cutting.
  • In addition, if you are using an angle grinder to cut concrete or other hard materials, always keep a bucket of water nearby to douse the spinning blade in case of kickback.

Angle grinders can cause severe injury if used improperly.


You can use an angle grinder for a variety of purposes. Whether you are doing construction, remodelling your home or even taking on small projects around the house, there is an angle grinder for every job.
