Buying Guide
- Tool type and motor power: For metal cutting and heavy-duty tasks, prioritize higher amperage grinders or cut off tools. Cordless models add portability but may trade runtime for power.
- Speed and materials: Higher no-load RPM facilitates faster cuts in thin metal; ensure blades or wheels are rated for your chosen materials.
- Safety features: Look for double insulation, wheel guards, and brake systems to reduce kickback and heat buildup during use.
- Interchangeable wheels and accessories: A kit with multiple wheels (cutting, grinding, sanding) increases versatility, especially in auto-body and fabrication work.
- Run time and duty cycle: For longer sessions, consider models with better heat management and cooling recommendations to prevent overheating and maintain performance.
- Portability vs. power: Cordless tools offer mobility in tight spaces or outdoor sites, while corded tools deliver consistent power for continuous cuts.
- Maintenance and durability: Brushless motors typically offer longer life and cooler operation, though they may come at a higher upfront cost.
- Weight and balance: A comfortable grip reduces fatigue during extended jobs; look for balanced ergonomics and vibration control features.
