Buying Guide

Motor amperage and RPM

Look for higher amperage (around 6–9A) and RPM ratings near 11,000–11,800 for efficient cutting and grinding on metal and masonry

Disc size compatibility

Most budget corded grinders use 4-1/2 inch discs—confirm compatibility with cutting, grinding, and flap discs you plan to use

Ergonomics and auxiliary handle

Choose a model with a comfortable grip and a removable side handle to improve control during extended use and angled cuts

Dust management

If you'll work on concrete or drywall, consider adding a dust shroud accessory compatible with 4.5–5 inch grinders to reduce airborne debris

Safety features

Prioritize grinders with a guard that adjusts without tools, a spindle lock for safe wheel changes, and a secure power switch to prevent accidental starts
