The Bosch GWS8-45 4-1/2 In. Angle Grinder is a light, ergonomic grinder, with a slender grip circumference that allows users to work comfortably for extended periods. This 4.2 Lbs. tool delivers plenty of power, with a 7.5-amp motor that produces 11,000 no-load rpm. It has directed air flow that diverts dust away from vital components. Bosch's Service Minder™ brush system shuts off the tool when preventative maintenance is required, which helps to eliminate guesswork. This grinder has a two-position side handle. It has a burst-protection quick adjustable guard designed for user protection, a fast-change disc change and a large spindle lock.
