Bosch GBH18V-40CK27 PROFACTOR 18V 1-5/8" SDS-Max Rotary Hammer Kit
The Bosch GBH18V-40CK27 PROFACTOR 18V 1-5/8-inch SDS-Max cordless rotary hammer delivers 6.7 ft-lbs of EPTA impact energy for high-speed concrete coring, structural rebar doweling, and heavy chiseling. Driven by a high-performance BITURBO Brushless motor paired with two CORE18V 12.0Ah High Power batteries, this 18.4-lb cordless demolition hammer rivals corded tools in drilling speed, chipping removal rate, and continuous runtime. Equipped with KickBack Control sensor technology, dual-mode operation with Vario-Lock chisel positioning, an integrated anti-vibration air cushion dampener, and a high-power Turbo Charger with Power Boost mode, it ensures maximum operator safety and relentless productivity on commercial masonry jobsites.
Best Used For:
- Structural Rebar Doweling and Heavy Concrete Anchoring: Boring 5/8-inch to 1-5/8-inch diameter anchor holes into high-PSI cured concrete foundation walls and footings.
- Commercial Masonry and Tile Demolition: Chipping structural block, scaling excess mortar spatter, and stripping floor tiles in hammer-only mode using Vario-Lock flat chisels.
- Through-Wall Mechanical and Electrical Penetrations: Driving large SDS-Max core bits through reinforced concrete and hollow cinder block partitions for conduit and piping rough-ins.
Key Performance & Safety Features
- BITURBO Brushless Technology: High-output brushless motor drivetrain engineered specifically to maximize high-current discharge from CORE18V 12Ah battery cells.
- 6.7 Ft-Lbs EPTA Impact Energy: Hard-hitting electro-pneumatic striker mechanism delivers fast drilling penetration and rapid material removal in tough aggregate.
- Integrated KickBack Control: Built-in accelerometers automatically decouple the motor within milliseconds during sudden bit binding to prevent dangerous tool kickback.
- Multi-Stage Anti-Vibration Architecture: Extended internal pneumatic air cushion and decoupled handle dampeners drastically isolate vibration away from operator hands.
- On-Tool Digital User Interface: Interactive display provides real-time tool status, operational temperature feedback, battery life indicators, and customized mode settings.
- Vario-Lock Chisel Orientation: Allows operators to rotate and lock SDS-Max chisels into multiple distinct angular positions for optimal attack angles while chipping.
