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 In. diameter bit, drilling 2 In. 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.
