This D-handle Bulldog Hammer consistently outperforms the best selling 1" corded 11255VSR Bulldog, making it better than the best. It features a hammer that 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 kit features two CORE18V High Power Batteries, which deliver 2x the power and runtime as two-layer 4.0 Ah batteries with minimal increase in volume and weight.
