Buying Guide: Key Purchase Considerations
- Power and RPM: Match motor amperage and RPM to your workload. Higher RPM helps with fast material removal but requires careful operation to avoid overheating or kickback.
- Guard Design: Tool-less or One-Touch guards speed up changes and improve safety on crowded workbenches.
- Weight and Balance: Lighter grinders reduce fatigue on extended jobs; consider side handles for better control in awkward angles.
- Corded vs. Cordless: Corded models offer consistent power for prolonged tasks; cordless options excel in tight spaces or mobile setups.
- Durability: Look for metal gear housings and dust ejection systems to extend tool life in metalworking environments.
- Accessibility of Discs: Spindle size and disc compatibility influence which wheels you can use and how quickly you can swap accessories.
