This 1″ cordless rotary hammer kit delivers the maximum in mobility, impact and movement toward OSHA compliance. The kit includes the 18V EC Brushless 1″ SDS-plus Bulldog Rotary Hammer, a cordless SDS-plus Mobile Dust Extractor and two CORE18V Lithium-ion batteries. The GBH18V-26D D-handle hammer consistently outperforms the best-selling 1″ corded 11255VSR Bulldog, making it better than the best. The hammer delivers 1.9 Ft.-Lbs. of impact energy, based on the European Power Tool Association (EPTA) industry standard. It weighs only 5.8 Lbs. (tool only, not including battery), for an outstanding impact-to-weight ratio. The cordless GDE18V-26D Mobile Dust extractor features a HEPA filter, helping users move toward compliance with OSHA silica regulations. The dust canister capacity can accommodate up to 20 holes using a 1/2″ diameter bit, drilling 2″ deep into concrete. The CORE18V batteries include an 8.0 Ah Performance and a 4.0 Ah Compact. Engineered with 21700 cell technology, they deliver advanced power plus CoolPack 2.0 technology to manage the heat.
