Intro Angle grinders are one of the most versatile power tools for metalworkers, masons, fabricators, and home renovators. They cut, grind, strip paint, and polish. Choosing the right model depends on disc size, motor cooling, guard design, vibration control, and whether you need cordless portability. This guide gives trusted models for heavy removal, precision finish, cordless jobsite work, and masonry cutting.

Angle grinder buying checklist (what to check before buying)
- Disc compatibility and max RPM rating — never use a disc rated below the grinder speed.
- Guard design and quick adjust features.
- Vibration isolation and anti-vibe handles.
- Motor cooling and sealed bearings for dusty jobs (masonry).
- Accessory compatibility (flap wheels, diamond cups, wire brushes).
- Battery platform considerations (for cordless): choose a platform you already own or plan to commit to.
Safety & use tips
- Always use the proper guard and position it between you and the sparks/debris.
- Use two hands and a firm stance; sparks can catch clothing.
- Wear safety glasses (or full-face shield), hearing protection, respirator for dusty work, gloves, and flame-resistant clothing where sparks occur.
- Let discs cool before storing; never store a hot disc in contact with other tools.
Maintenance
- Inspect discs before every use for chips or cracks.
- Replace worn brushes and clean vents to maintain cooling.
- Keep tool shafts and clamping shoulder surfaces clean for secure disc mounting.
