Bosch 18-volt 8 -Amp SDS-Max SDS-max Variable Speed Cordless Rotary Hammer Drill

This 18V Hitman SDS-max® 1-7/8 In. rotary hammer delivers corded-type performance for heavy-duty concrete drilling and chiseling jobs. The Bosch GBH18V-45CK 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 17.6 Lbs. (tool only, not including 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 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. It has connectivity (module sold separately) to link to connected device via Bosch Toolbox App to customize settings and receive detailed feedback.
