The reasonably high rotational speed of approximately 8,400 rpm helps maintain productivity, and the rugged construction supports everyday use in tougher conditions. While the tool is heavier than smaller grinders due to its larger motor and disc size, its design provides the leverage and control necessary for sustained work.

Best Suited For:

✔ Cutting steel beams, rods, and structural stock
✔ Grinding weld seams and smoothing rough surfaces
✔ Preparing metal or concrete surfaces for finishing work
✔ Fabrication, construction, and general workshop use

User Tips

Safety First

Always wear eye protection, hearing protection, and gloves when using an angle grinder — sparks and debris are typical.

Use Correct Discs

Select discs rated for 180 mm (7″) diameter and appropriate for the material being worked on (e.g., metal cutting wheels for steel, grinding discs for surface prep).

Secure Your Workpiece

Clamping or stabilizing the material improves cutting precision and minimizes the risk of kickback or shifting during operation.

Maintain Tool Coolness

Keep ventilation slots clear of dust and debris to support airflow and help prevent overheating during extended work periods.
