Introduction to Angle Grinder Risks

Angle grinders operate at high speeds up to 12,000 rpm, making them dangerous if not handled properly. The video aims to share essential safety tips.

Check discs for cracks or missing pieces to prevent them from flying apart. Discard faulty discs immediately.

[01:30]
Unplug When Adjusting

Always unplug the grinder when replacing discs or making adjustments to avoid accidental activation.

Control Spark Direction

Aim sparks toward the ground or low-risk areas to prevent fires or embedding in materials like plastic, which can cause rust over time.

Following these five safety tips—using guards, inspecting discs, unplugging during adjustments, wearing proper gear, and controlling sparks—can significantly reduce the risk of injury when using an angle grinder.
