Buying Guide

Choose by power source

Corded grinders (measured in amps) deliver consistent power for extended cuts, while cordless 18V options offer portability—select based on jobsite mobility needs

Match motor power to task

Higher amp or RPM ratings suit heavy grinding and cutting; for light cleanup, lower-powered 4–6 amp tools are adequate and lighter to handle

Consider wheel size and compatibility

Most tools here use 4-1/2 inch wheels—confirm spindle thread and guard compatibility with grinding, sanding, or cutting discs you plan to use

Look for comfortable controls and safety features

A side handle, paddle or trigger switch, and effective guards improve control; consider models with lock-off switches to reduce accidental starts

Factor in battery ecosystem

If choosing a cordless 18V model, consider the brand’s battery platform so you can share batteries with other tools for better value
