This 18V Hitman 1-7/8 In. SDS-max® rotary hammer delivers corded-type performance for heavy-duty concrete drilling and chiseling jobs. The Bosch GBH18V-45CK24 Hitman Rotary Hammer delivers 9.3 Ft.-Lbs. of impact energy (EPTA). That is unprecedented for a single-battery 18V 1-7/8 In. SDS-max® rotary hammer. It weighs 19.6 Lbs. (with included battery). This hammer is part of the PROFACTOR System, which pairs BITURBO Brushless Technology with a CORE18V PROFACTOR battery. BITURBO Brushless Technology is a high-performance motor and drive-train system designed to deliver power comparable to high-demand corded tools. It has KickBack Control, rotary hammer and hammer-only modes, and Vario-Lock to rotate and lock the chisel. The anti-vibration system features a longer air cushion in the hammer tube, dampeners in the handle and a counter-balance weight in the hammer mechanism. It also has Soft Start and controlled rpm and bpm, making it easier to control drilling and chiseling applications. The hammer features an on-tool user interface for tool performance, feedback, and control. This hammer features connectivity (module sold separately) to link to the free Bosch Toolbox app. The kit includes two CORE18V PROFACTOR Performance Batteries and a turbo charger with a turbo power boost mode that can charge a CORE18V 8.0 Ah PROFACTOR Performance Battery up to 50% charge in 15 minutes and up to 80% in 26 minutes.
