Safety Tips When Using an Angle Grinder

Angle grinders are very useful and versatile tools, but they also require caution as the grinding discs rotate at very high speeds. Here are some important safety tips to follow when using an angle grinder:

Always wear proper PPE – At a minimum this includes safety goggles, face shield, hearing protection, long sleeves, and thick work gloves. A dust mask is also recommended.

Check your disc – Inspect the grinding disc for cracks or damage before using it. Make sure it is properly rated for the material you are working on.

Use both hands – One hand should grip the main handle, while the other hand holds the side assist handle. This allows maximum control.

Don’t force the grinder – Let the disc do the work by using light pressure. Forcing it can cause kickback or damage to the disc.

Avoid pinch points – Keep hands and body parts away from where the spinning disc meets the workpiece. Accidental contact can cause severe cuts.

Don’t let it bind – If the disc binds or gets wedged in a cut, turn the grinder off immediately. Forcing it when stuck can cause kickback.

Control sparks – Angle grinders throw sparks. Make sure there are no flammable liquids or gases nearby. Have a fire extinguisher on hand.

Use a sturdy platform – For maximum stability, avoid using the grinder while on a ladder or unstable surface.

Unplug when not in use – Turn the grinder off and unplug it when changing discs or making adjustments.

By following these guidelines, you can operate your angle grinder safely and get years of productive use from it on all your metal and concrete jobs.
