Buying Guide
What should you consider when choosing grinding wheels for angle grinders?
- Grit type and grain: Aluminum oxide is common for metal; ceramic grains offer longer life in heavy duty tasks.

- Purpose: Whether you need cutting, grinding, or stock removal will determine the wheel type and grit.
- Life vs. aggressiveness: Higher grain concentration increases aggressiveness but may wear faster in some materials.
- Safety and PPE: Always use eye protection, gloves, and a face shield; ensure proper wheel guards and RPM ratings.
