Reports indicate customers in the grinding wheel industry break approximately one grinding wheel per day. Grinding wheel guards are one of the key components in keeping these grinding wheel mishaps from becoming a personal injury. In Summary: Grinding wheel guards designed for one type of machine and used on another type of machine or the wrong guards for the type of wheel are dangerous.
There are two popular types of safety guard: disc/wheel guard & dust guard. To make the most use of an angle grinder guard, you should adequately attach the disc guard to the grinder for your maximum safety so that the least of the wheel is exposed to you. An angle grinder guard is an irreplaceable part of an angle grinder.
Wheel guards serve to deflect sparks and debris away from users, and to shield and protect them from abrasive cutting and grinding wheels, which can cause serious damage if they fail and fly off. Angle grinder wheel guards are often adjustable, with newer styles, such as the new Dewalt wheel guard shown here, aiming to be more featured and user-friendly. A lot of users remove the wheel guards off their angle grinders, with the most frequent reason I’ve heard being that the guards get in the way of the work.
