This Bosch D-handle Bulldog™ hammer consistently outperforms the best-selling 1 in corded 11255VSR Bulldog™, making it better than the best. The GBH18V-26DK24 18 V EC brushless 1 in SDS-plus® Bulldog™ rotary hammer kit features a hammer that delivers 1.9 ft-lb of impact energy, based on the industry standard of measurement agreed upon by the European Power Tool Association (EPTA). It weighs only 5.8 lb, delivering superior performance and an outstanding impact-to-weight ratio. The kit features two CORE18V performance batteries, which deliver 2X the power and runtime as two-layer 4 Ah batteries with minimal increase in volume and weight. They are engineered with 21700 cell technology. Bosch engineered the exclusive CoolPack 2.0 technology to manage the heat of the higher power-density cells. The hammer's EC brushless motor maximizes battery runtime for extended performance. The tool features a jobsite-proven D-handle design with soft-grip and is ideal for overhead, horizontal and downward drilling applications. It also has KickBack control and a variable-speed reversing trigger for accurate bit starting.
