User Tips

Safety First

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

Choose the Right Disc

Use discs rated for 180 mm (7″) diameter and appropriate for your task (e.g., cutting wheels for steel, grinding wheels for concrete).

Clamp Workpiece

Securing the material you’re working on improves accuracy and reduces risk of kickback.

Manage Heat & Debris

Keep ventilation ports free of buildup and allow occasional breaks during heavy work to prevent overheating.
