Air Grinders

Air Die Grinders & Angle Grinders for Metal & Auto Work

Shape, smooth, and finish with precision using Le Lematec's pneumatic grinder lineup. From compact die grinders for detail work to heavy-duty 4-1/2" angle grinders for aggressive cutting and grinding, our air-powered grinders deliver consistent RPM without the weight and heat buildup of electric alternatives. Available in straight, angle, and flexible configurations to reach any workpiece.

Choosing Your Grinder

Die grinders (straight and flexible) accept 1/4" shank accessories — mounted points, carbide burrs, sanding drums, and flap wheels for deburring, porting, polishing, and carving. Angle grinders (4" and 4-1/2") use standard cutting and grinding wheels for fast material removal, weld grinding, and metal cutting. Belt sanders handle contour work and finishing on curved surfaces.

Frequently Asked Questions

Q: What is the difference between a die grinder and an angle grinder?

A: Die grinders use small mounted accessories (burrs, stones, drums) on a 1/4" collet for precision work — deburring, porting, polishing. Angle grinders use larger cutting/grinding discs (4-4.5") for aggressive material removal. Die grinders are for detail work; angle grinders are for heavy stock removal.

Q: Do air grinders need lubrication?

A: Yes. Add 2-3 drops of air tool oil into the air inlet before each use session. This lubricates the internal vane motor, extends tool life, and maintains full RPM performance. An inline oiler automates this for heavy daily use.
