Buying Guide

Match motor amperage to the task

Higher-amp motors (e.g., 11A) deliver sustained power for heavy grinding and cut-off work, while lower-amp units are lighter for light-duty prep and finishing

Choose the right disc size

4-1/2 inch wheels are standard for metal prep—combining access in tight spots with availability of grinding and cutting discs

Prefer adjustable guards and side handles

A removable or adjustable guard and a multi-position side handle improve control and safety when working on different metal shapes and angles

Consider corded vs cordless power

Corded grinders provide steady high current for demanding fabrication tasks, while cordless models offer portability for light to medium prep jobs

Check rpm and no-load speed

Higher no-load RPM supports faster material removal, but match speed to disc specifications to avoid premature wear or unsafe operation
