Speedaire air-powered die grinders are designed to rotate cartridge rolls, mounted points, carbide burs, flap wheels and other connectors for deburring, polishing and grinding operations. These die grinders set their grinding head in check with the tool body and feature a compact profile to reach through spaces where an angled head may not fit. Choose from a range of these die grinders, available in 0.3, 0.35, 0.4 and 0.5 HP power options.
