Bosch GBH18V-36CK27 PROFACTOR Hitman 18V 1-9/16" SDS-Max Rotary Hammer Kit

The Bosch GBH18V-36CK27 PROFACTOR Hitman 18V 1-9/16-inch SDS-max cordless rotary hammer delivers 5.2 ft-lbs of EPTA impact energy for high-speed concrete coring, structural rebar doweling, and heavy masonry chiseling. Driven by a high-output BITURBO Brushless motor paired with two CORE18V 12.0Ah High Power batteries, this 14.3-lb commercial-grade hammer operates at 0-500 RPM and 0-2,900 BPM to bore solid carbide drill bits up to 1-9/16 inches and core bits up to 4 inches in cured concrete. Featuring sensor-driven KickBack Control, a 12-position Vario-Lock chisel system, dual-stage anti-vibration damping, an on-tool digital display, and a 16-amp high-power Turbo Charger, it provides cordless mobility without sacrificing demolition velocity on commercial construction jobsites.

Best Used For:

  • Commercial Foundation Anchoring and Doweling: Drilling large 1/2-inch to 1-9/16-inch anchor holes into reinforced cured concrete footings and retaining walls.
  • Structural Core Penetrations: Boring through-wall electrical conduit, plumbing pipe, and HVAC line passages using SDS-max core bits up to 4 inches in diameter.
  • High-Impact Masonry and Tile Demolition: Chipping mortar spatter, channeling concrete masonry units (CMU), and lifting floor tiles in hammer-only mode using Vario-Lock flat chisels.

Key Performance & Safety Features

  • BITURBO Brushless Powertrain: High-performance brushless motor optimized to draw maximum current from CORE18V 12Ah batteries, generating 5.2 ft-lbs of EPTA impact energy.
  • Integrated KickBack Control: Built-in acceleration sensors decouple the motor within milliseconds during sudden bit binding to prevent violent tool reaction.
  • Dual-Stage Anti-Vibration Isolation: Combines an elongated internal pneumatic air cushion inside the cylinder with rubber-insulated handle dampeners to minimize arm fatigue.
  • 12-Position Vario-Lock Chisel Rotation: Enables operators to rotate and securely lock SDS-max chisels into 12 distinct attack angles for optimal positioning in tight corners.
  • On-Tool Digital User Interface: Interactive LCD screen displays real-time tool diagnostics, thermal overload warnings, and exact battery cell charge levels.
  • 16-Amp Fast Turbo Charger: Ultra-fast charging station includes an optional Power Boost mode to recharge high-capacity 12.0Ah battery packs rapidly between shifts.

Pro-Tip: Before boring large 4-inch core penetrations, clean dust out of the SDS-max chuck and apply high-pressure grease to the bit shank; regular shank lubrication maintains optimal impact transfer and prevents heat-induced bit seizure during deep continuous boring.
