Bosch GBH18V-26 18V EC Brushless 1" SDS-Plus Bulldog Cordless Rotary Hammer - Bare Tool

The Bosch GBH18V-26 18V EC brushless 1-inch SDS-Plus Bulldog rotary hammer delivers corded-class concrete drilling, overhead anchoring, masonry core boring, and light chiseling. Generating 1.9 ft-lbs of impact energy at 0 to 4,350 BPM and 0 to 890 RPM, this 6.3-lb cordless hammer provides an exceptional power-to-weight ratio to reduce user fatigue during long drilling passes. Outfitted with integrated KickBack Control anti-bind sensors, Electronic Precision Control for soft bit starts, Vibration Control dampening, Electronic Motor and Cell Protection, and an ergonomic L-shaped chassis, it delivers operator safety, precision bit tracking, and relentless drilling velocity across commercial construction sites.

**Battery and charger sold separately.

Best Used For:

  • Commercial Concrete Mechanical Anchor Drilling: Boring 3/8-inch to 5/8-inch anchor holes for wedge anchors, screw anchors, and threaded rod drops in cured slabs and ceilings.
  • Overhead MEP Conduit and Pipe Hanger Fastening: Drilling inverted anchor holes quickly in post-tensioned concrete ceiling decks with minimal arm strain.
  • Light Masonry Chiseling and Mortar Dressing: Scaling mortar spatter, chasing electrical conduit channels in concrete blocks, and removing ceramic floor tile using hammer-only mode.

Key Performance & Safety Features

  • EC Brushless Motor Architecture: Delivers 1.9 ft-lbs of impact energy while increasing battery efficiency and motor operating lifespan.
  • Integrated KickBack Control: Built-in acceleration sensor detects sudden rotational bind-ups and automatically shuts down motor rotation to prevent wrist injuries.
  • Electronic Precision Control (EPC): Regulates initial power ramp-up to 70% for clean, precise bit starts without walking on smooth tile or polished concrete.
  • Active Vibration Control Mechanism: Counter-balanced dampening system isolates handle vibrations, providing superior operator comfort during extended hammer drilling.
  • Dual-Mode Selector: Easily switches between rotary hammer drilling and hammer-only chiseling passes to adapt to diverse commercial tasks.
  • Electronic Motor & Cell Protection (EMP/ECP): Guards internal motor windings and battery cells against high temperatures, electrical overloads, and deep discharges.

What's Included

  • (1) Bosch GBH18V-26 18V EC Brushless 1" SDS-Plus Bulldog Rotary Hammer (Tool Only)
  • (1) 360-Degree Auxiliary Side Handle
