OSHA's Angle Grinder Safety Requirements
The Occupational Safety and Health Administration (OSHA) has strict guidelines for the safe operation of angle grinders. According to OSHA statistics, kickbacks from grinders and saws are a leading cause of workplace injuries, some even resulting in fatalities. View OSHA's official safety guidelines here.
OSHA Safety Requirements for Angle Grinders:
-
Use the proper wheel or disc for the task—cutting, grinding, or polishing all require specific accessories.
-
Check the grinder before use—ensure all guards and handles are securely in place.
-
Do not exceed the maximum RPM rating of the disc or wheel.
-
Wear proper personal protective equipment (PPE), including safety glasses, a face shield, gloves, and hearing protection.
-
Ensure a safe work environment—keep the work area free of clutter and secure the workpiece properly.
-
Inspect wheels before use—never use damaged or expired wheels.
-
Use two hands on the grinder at all times for maximum control.
-
Disconnect power before changing wheels or making adjustments.
Pro Angle Grinder Safety Tips
In addition to OSHA’s guidelines, professional tradespeople follow additional best practices to minimize risks while using angle grinders. Here are some pro tips from our team at Delta Diamond Products:
-
Choose the Right Diamond Blade – Using an improper blade increases the risk of kickback and blade failure.
-
Wear Wide-Vision Goggles & Face Shield – Standard safety glasses are not enough to protect against flying debris.
-
Hold the Grinder Properly – Maintain a firm grip with both hands on the auxiliary and main handles.
-
Position the Workpiece Securely – Use a vice or clamps when possible to prevent movement.
-
Use the Correct Angle – Keep the grinder at a 15- to 30-degree angle when grinding to avoid digging in.
-
Avoid Excessive Pressure – Let the blade do the work; applying too much force increases the chance of kickback.
-
Never Use a Cutting Wheel for Grinding – Cut-off wheels are not designed for lateral pressure and can shatter.
-
Do Not Remove the Guard – The safety guard is there to deflect debris and prevent serious injuries.
-
Allow the Grinder to Reach Full Speed – Before applying it to the workpiece, let the disc stabilize at full RPM.
-
Store and Handle Blades Properly – Always inspect and discard cracked or damaged blades to prevent accidents.
By following these pro safety tips, you’ll ensure a safer work environment and prolong the life of your diamond blades and grinder.
