Bosch GBH18V-28CK28 18V Brushless Bulldog™ 1-1/8" SDS-plus® Rotary Hammer Kit with (2) CORE18V 8.0Ah Batteries

The Bosch GBH18V-28CK28 18V brushless Bulldog™ 1-1/8-inch SDS-plus® rotary hammer kit bores concrete anchor holes, drills masonry cores, and executes heavy demolition chiseling with 2.6 ft-lbs of EPTA impact energy and 4,220 BPM. Powered by an industrial brushless motor matched with two high-capacity CORE18V® 8.0Ah high-power lithium-ion batteries, this cordless drilling system maintains consistent rotational torque up to 950 RPM through aggregate rock, solid reinforced concrete, and tough masonry blocks. Outfitted with sensor-based KickBack Control to stop sudden rotational bind-ups, an integrated Anti-Vibration System to mitigate joint fatigue, an interactive on-tool user interface display, and a 12-position Vario-Lock™ chisel collar, it equips commercial electricians, mechanical plumbers, and structural masonry crews with durable drilling and chipping productivity.

Best Used For:

  • Structural Concrete Anchoring and Core Drilling: Boring heavy-duty 1/2-inch to 1-1/8-inch mechanical anchor holes and up to 3-inch thin-wall core bit passages through commercial concrete foundations.
  • Overhead MEP Conduit and Pipe Hanger Installations: Drilling repetitive drop-in anchor holes in concrete ceilings and elevated slab decks with reduced vibration fatigue.
  • Tile Scraping and Mortar Joint Chiseling: Locking flat chisels and scaling blades into 12 distinct positions using Vario-Lock™ for controlled surface demolition and masonry prep.

Key Performance & Safety Features

  • 2.6 Ft.-Lbs. Hard-Hitting Impact Energy: Engineered to match corded hammer striking force for rapid penetration through hard aggregate and concrete.
  • Sensor-Based KickBack Control: Integrated acceleration sensors automatically shut down motor power in a fraction of a second if the bit binds up against rebar.
  • Dual High-Power CORE18V® 8.0Ah Batteries: Next-generation 21700 cell architecture delivers corded-class wattage output and advanced thermal heat management.
  • Internal Anti-Vibration Counterbalance: Built-in structural dampeners actively absorb impact shock waves before they reach the operator's hands and arms.
  • Interactive On-Tool User Interface: High-visibility digital screen provides real-time tool diagnostics, motor temperature feedback, and battery state-of-charge data.
  • 12-Position Vario-Lock™ Collar: Allows operators to rotate and lock scaling and demolition chisels into the optimum working angle.
  • AMPShare™ Multi-Brand Compatibility: Batteries and charger operate seamlessly across the global multi-brand alliance cordless tool platform.

Pro-Tip: When drilling holes for heavy structural anchors, allow the 2.6 ft-lbs electro-pneumatic hammer mechanism to do the work with moderate forward guidance; pressing excessively hard dampens the internal striker stroke and slows down drilling speed.
