This 18V SDS-plus® Bulldog™ 1-1/4 In. rotary hammer is powerful enough to provide corded-type performance for tackling heavy-duty concrete drilling or chiseling jobs. The Bosch GBH18V-34CQ Rotary Hammer delivers 4.3 Ft.-Lbs. of impact energy (EPTA). That is unprecedented for a single 18V battery-driven SDS-plus® 1-1/4 In. rotary hammer. It weighs 10.8 Lbs. (tool only, not including 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. The anti-vibration system helps reduce vibration with a longer air cushion in the hammer tube and dampeners in the handle. The hammer has KickBack Control, a quick-release chuck, rotary hammer and hammer-only modes, a reverse setting and Vario-Lock to rotate and lock the chisel. 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. 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.

  • Powerful, cordless 1-1/4 In. SDS-plus® rotary hammer.
  • KickBack Control and anti-vibration technology for comfort.
  • PROFACTOR™ tools are BITURBO Brushless™ to deliver corded power.
