Product Highlights

This 18V SDS-max® 1-7/8 In. rotary hammer delivers corded-type performance for heavy-duty concrete drilling and chiseling jobs. The Bosch GBH18V-45CK24 Rotary Hammer delivers 9.3 Ft.-Lbs. of impact energy (EPTA). That is unprecedented for a single-battery 18V SDS-max® 1-7/8 In. 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® High Power 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® 8 Ah High Power Batteries, which each deliver 50% more runtime and over 75% more power than the CORE18V® 4 Ah battery, powering high-demand applications. The GAL18V-160C battery turbo charger provides 16-amp charging current for fast and faster charging, with an optional Power Boost™ mode.
