User Tips

Safety First

Always wear eye protection, hearing protection, and sturdy gloves when using an angle grinder — sparks and debris are common during cutting and grinding.

Correct Disc Selection

Use grinding or cutting wheels that are rated for 125 mm (5″) diameter and matched to your specific task (e.g., metal cutting discs for steel, grinding wheels for surface preparation).

Secure Workpiece

Clamp the material you’re working on to prevent movement and improve cutting accuracy.

Ventilation & Heat

Keep the tool’s ventilation ports clear of dust and debris to promote proper cooling and maintain consistent performance.
