What is an Angle Grinder Used for? A Complete Guide

An angle grinder is a versatile power tool that can be used for a variety of tasks, from cutting and grinding to polishing and sanding. It can also be used for sharpening, deburring, and removing rust and paint. But what exactly is an angle grinder and how does it work? And what are the best ways to use it safely and effectively? In this article, we will answer these questions and more, so you can get the most out of your angle grinder.

What is an Angle Grinder?

An angle grinder is a handheld tool that has a rotating disc or wheel at a 90-degree angle to the handle. The disc or wheel can be fitted with different attachments, such as abrasive discs, diamond blades, wire brushes, flap discs, and polishing pads. The angle grinder can be powered by electricity, compressed air, or a battery.

The angle grinder works by spinning the disc or wheel at a high speed, creating friction and heat that can cut or grind through various materials, such as metal, wood, concrete, stone, and tile. The angle grinder can also be used to smooth, polish, or clean surfaces by using different types of attachments and applying different levels of pressure.

How to Use an Angle Grinder Safely and Effectively

An angle grinder is a powerful tool that can perform many tasks, but it also comes with some risks and challenges. Here are some tips on how to use an angle grinder safely and effectively:

  • Wear proper protective gear. An angle grinder can produce sparks, dust, and debris that can injure your eyes, ears, skin, and lungs. Therefore, you should always wear safety glasses, gloves, ear plugs, and a dust mask when using an angle grinder. You should also wear long sleeves, pants, and sturdy shoes to protect your body from flying particles and hot metal.
  • Choose the right attachment for the job. An angle grinder can be used with various attachments, but not all of them are suitable for every task. For example, you should use a metal-cutting disc for cutting metal, a diamond blade for cutting concrete or stone, a wire brush for removing rust or paint, and a polishing pad for polishing metal or wood. You should also check the size, speed, and direction of the attachment before using it, and make sure it is compatible with your angle grinder model and power source.
  • Secure the workpiece and the angle grinder. An angle grinder can generate a lot of force and vibration, which can cause the workpiece or the angle grinder to move or slip. To prevent this, you should always secure the workpiece with clamps or a vise, and hold the angle grinder firmly with both hands. You should also avoid using the angle grinder above your head or in awkward positions, as this can increase the risk of losing control or dropping the tool.
  • Use the correct technique and pressure. An angle grinder can be used for different purposes, but you should always use the correct technique and pressure for each one. For example, when cutting or grinding, you should use a smooth and steady motion, and let the disc or wheel do the work. You should not force the angle grinder into the material, as this can cause the disc or wheel to overheat, wear out, or break. When polishing or sanding, you should use a light and gentle pressure, and move the angle grinder in circular or back-and-forth motions. You should not apply too much pressure, as this can damage the surface or the attachment.
  • Maintain and store the angle grinder properly. An angle grinder is a durable tool, but it still needs regular maintenance and proper storage to keep it in good condition. You should always clean the angle grinder after each use, and remove any dust or debris from the vents, the disc or wheel, and the attachments. You should also check the cord, the switch, the bearings, and the brushes for any signs of damage or wear, and replace them if necessary. You should store the angle grinder in a dry and cool place, and keep it away from moisture, heat, and direct sunlight.
