User Tips

Safety Gear

Always wear eye protection, gloves, and proper hearing protection when operating an angle grinder — sparks and debris are common during use.

Correct Disc Selection

Use discs rated for the material you’re working on (e.g., metal cutting wheels for steel and grinding discs for surface prep).

Secure Workpiece

Clamp or otherwise secure the material you’re working on to improve accuracy and reduce the risk of movement during operation.

Break-In

When using the tool for the first time, run it briefly at moderate pressure to help seat internal components and familiarize yourself with its handling characteristics.
