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 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. The kit includes two CORE18V PROFACTOR Performance Batteries, which are compatible with Bosch 18V tools, and optimized to drive Bosch PROFACTOR tools with BITURBO Brushless Technology, for power comparable to the most demanding corded tools. The kit has a Hell-ion Turbo Charger with a turbo power boost mode that can charge a CORE18V 8.0 Ah PROFACTOR Performance Battery up to 50% charge in 15 minutes and up to 80% in 26 minutes. The Bosch GDX18V-1860C Two-in-One Cordless Impact Driver/Wrench provides one tool for use with bits and sockets. It goes from impact wrench to impact driver fast. The two-in-one bit/socket drive increases both convenience and power. Bits can stay conveniently inserted when using deep sockets, and more torque is transferred directly thru the 1/2 In. square drive anvil. There is no more torque loss through socket adapters or broken socket adapters. The impact driver/wrench’s efficient, powerful brushless motor produces up to 1,860 In.-Lbs. of torque and 0-4,100 impacts per minute. In addition to three speed/torque settings this impact driver/wrench also features special modes to prevent work piece and fastener damage. The presets include modes for self-drilling metal screws and wood screws. Additional modes and customizations for specific screws and materials can be set and saved to the tool via the Bosch Toolbox App (connectivity module sold separately). In reverse, with bolt mode activated, the Auto Bolt Release stops rotation when there is no load on the tool to prevent accidentally dropping bolts and nuts during removal. In addition to customizing settings and modes, connectivity (module sold separately), provides tool specific information and feedback. The variable-speed trigger provides accurate driving speed. It also has an LED light system to illuminate the work area.
