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 1-1/4 In. SDS-plus® 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.
