The Bosch 11255VSR-GWS8 Two-Tool Kit provides a convenient way to acquire two professional tools, and it features the 11255VSR 1" SDS-plus® Bulldog™ Xtreme Rotary Hammer and a GWS8-45 4-1/2" Angle Grinder. The Bosch 11255VSR hammer provides legendary Bulldog™ performance, with a powerful 7.5 Amp motor and a multi-function selector that matches mode to the task at hand: drilling only, hammer drilling and chiseling. Providing 2.0 Ft.-Lbs. of impact energy, the tool weighs only 6.7 Lbs., for a top performance-to-weight ratio, which will have users getting the job done and fast. The hammer has an integral clutch that helps to minimize torque reaction and a 36-position Vario-Lock system that helps optimize the chiseling angle. The GWS8-45 4-1/2" Angle Grinder is one of the most powerful small-angle grinders available. The grinder features a two-position side handle that can switch from left to right, for additional control, as well as a comfortable slim-grip design. Bosch's Service Minder brush system shuts off the tool when preventative maintenance is required. Directed air flow diverts dust away from the vital components of the tool to extend its life.
