The Bosch GWS8-45-2P 4 1/2" angle grinder 2-pack features two angle grinders that deliver plenty of power. The GWS8-45 is a light, ergonomic grinder, with a comfortable grip circumference that allows users to work comfortably for extended periods. This 4.2 Lbs. tool has 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-switch disc change and a large spindle lock.
