The Bosch 1375A 4-1/2 In. Angle Grinder is designed for concrete contractors and other professionals who need a compact grinder. The 1375A is a light, ergonomic grinder, at only 3.75 Lbs. The tool has a 6.0-amp motor that produces 11,000 no-load rpm. With a well-designed grip, lock-on slide switch and two-position side handle, this workhorse can get the job done. Bosch's Service Minder brush system shuts off the tool when preventative maintenance is required, and the tool also features epoxy-coated field windings. This grinder has a burst-protection quick adjustable guard designed for user protection.
