The 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 PROFACTOR 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.

Features

• PROFACTOR performance – delivers corded hammer performance for an 18V 1-1/4 In. SDS-plus rotary hammer
• Superior impact – delivers 4.3 Ft.-Lbs. of impact energy (EPTA) for full performance in concrete when drilling and chiseling
• Compact, lightweight design – weighs only 10.8 Lbs. (tool only, not including battery) and is 17 In. long for maneuverability
• BITURBO Brushless Technology – featuring a brushless high-performance motor and drive-train system engineered to take full advantage of the additional power generated by CORE18V PROFACTOR batteries (sold separately)
• KickBack Control technology – reduces the risk of sudden tool reactions in binding conditions
• Quick-release chuck – allows for seamless change of the chuck from SDS-plus to a three-jaw chuck
• User interface – on-tool display helps manage tool performance for immediate feedback and control
• Anti-vibration system – helps reduce vibration with a longer air cushion in the hammer tube and dampeners in the handle
• Robust power system – produces 0-2,900 no-load bpm and 0-500 no-load rpm
• Vario-Lock positioning – rotates and locks chisel to optimize working angle
• Soft Start and controlled rpm – adjusts rpm and bpm for controlled drilling and chiseling applications in softer materials such as brick or tile
• Lock-on / lock-off button – keeps tool running when locked on (hammer-mode only) and prevents accidental activation of the trigger when locked off
• LED work light – illuminates dark work areas
• Reverse setting – provides easy removal if the bit gets jammed in concrete
