The Dos and Don'ts of Using an Angle Grinder

An angle grinder is a versatile power tool that supports both grinding and polishing. Also known as a side grinder, it features a disc. When turned on, the disc will rotate. Pressing this abrasive disc against an object will then grind or polish the object. While they may sound simple enough, however, angle grinders require some safety precautions.

Do Use the Right Type of Disc

You should use the right type of disc. All angle grinders support discs. There are many different types of discs, though. Low-grit discs are better suited for grinding hard and stubborn materials, whereas high-grit discs are better suited for softer materials. Regardless, you should use the right type of disc.

Do Inspect for Damage Before Use

Before using an angle grinder, take a minute to inspect it for damage. Make sure the disc is properly secured and not cracked or damaged. You should also check the power cord for signs of damage. If the disc is damaged, you can replace it. If the power cord is damaged, you may have to invest in a new angle grinder.

Do Wear PPE

One of the most important things to do when using an angle grinder is to wear personal protective equipment (PPE). Injuries can and do occur with angle grinders. Fortunately, there are several types of PPE available to lower the risk of injury. You should wear protective glasses or goggles, for instance, and you should wear earplugs. PPE such as this will allow you to safely use an angle grinder.

Don't Hold With One Hand

A common mistake workers make when using an angle grinder is holding it with one hand. Angle grinders are relatively small, but you should still hold them with both hands. When pressed against an object or workpiece, kickback may occur. Holding the angle grinder with two hands will allow you to control it in the event of kickback.

Don't Use on Unsecured Workpieces

Make sure the workpiece with which you are using the angle grinder is secured. If it's not secured, the angle grinder may sling it around. You can clamp the workpiece, or you can secure it using another method.

Don't Leave Running

When you are finished using an angle grinder, turn it off. Some workers place their angle grinders down while they are running. If an angle grinder is still running, the disc will spin. This spinning motion can cause angle grinders to essentially move on their own. Always turn off an angle grinder before placing it down.
