This Bosch D-handle Bulldog hammer consistently outperforms the best-selling 1 In. corded 11255VSR Bulldog, making it better than the best. The GBH18V-26D 18V Brushless 1" SDS-plus Bulldog Rotary Hammer delivers 1.9 ft-lbs of impact energy, based on the industry standard of measurement agreed upon by the European Power Tool Association (EPTA). It weighs only 5.8 lbs (tool only, not including battery), delivering superior performance and an outstanding impact-to-weight ratio. The efficient brushless motor combined with a CORE18V battery helps provide greater productivity and maximized runtime. The kit includes two CORE18V 4 Ah Advanced Power Batteries, which deliver lightweight, high power, and are equipped with CoolPack technology for extended life. 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, an integrated sensor to stop tool rotation in bind-up situations. The hammer features a variable-speed reversing trigger for accurate bit starting.
