Buying Guide: Key Purchase Considerations
- Battery Compatibility: Check whether the grinder uses common battery platforms you already own (e.g., Dewalt 20V MAX, Milwaukee M18). This can reduce overall cost and improve convenience.
- Motor Type: Brushless motors offer longer life and better efficiency, especially for frequent use. Compare brushless versus brushed models to match your workload.
