User Tips

Safety Gear

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

Use Appropriate Discs

Fit discs rated for 125 mm (5″) diameter and matched to your specific task (e.g., cutting wheels for metal, grinding wheels for surface work).

Secure the Workpiece

Clamping or stabilizing the material improves cutting accuracy and reduces the risk of kickback.

Maintain Tool Cleanliness

Keep ventilation ports clear of dust and debris to preserve cooling performance and extend tool life.
