Buying Guide: Key Purchase Considerations
- Power and speed: Most corded models range from 7 to 13 amps and 8,000–11,000 rpm. Higher amperage generally fuels tougher tasks, but balance with weight for extended use.
- Guard systems: One-Touch guards and adjustable guards reduce tool downtime and improve safety when changing discs.
- Dust management: Dust ejection systems help protect internal components in dusty environments, extending tool life.
- Ergonomics: Slim grips, paddle switches, and multi-position handles reduce fatigue and improve control, especially on extended jobs.
- Disc compatibility: Ensure the grinder supports the disc sizes you own (4-1/2″, 5″, or 7″), plus type 27 or type 29 guards for flexibility.
- Durability: Cast metal housings and robust brushes contribute to longevity on job sites with frequent drops and vibration.
- Accessories: Some models come with guards, wrenches, and flanges; consider whether you need a complete kit or a bare tool.
- Brand reliability: Leading brands often offer better service, replacement parts, and customer support, reducing downtime on projects.
