Bosch RH745 1-3/4" SDS-max Combination Rotary Hammer Drill

The Bosch RH745 1-3/4-inch SDS-max combination rotary hammer bores large-diameter anchor holes and chisels through heavy concrete slabs, foundations, and masonry walls during heavy demolition. Driven by a powerful 13.5-amp motor delivering 8.2 ft-lbs of EPTA impact energy and variable speeds up to 2,750 BPM, this rotary hammer provides professional-grade impact force with minimized vibration. Outfitted with a tool-free SDS-max bit system, Vario-Lock positioning supporting 12 chisel angles, a 360-degree auxiliary handle, and a Service Minder light indicator, it equips commercial contractors and demolition crews with reliable, high-performance percussion power.

Best Used For:

  • Heavy Concrete Demolition and Chipping: Breaking up reinforced concrete foundations, floor slabs, and masonry walls using the hammer-only mode.
  • Large-Diameter Core Drilling and Anchoring: Boring deep holes up to 5 inches in diameter for structural rebar and heavy mechanical anchors.
  • Overhead and Wall Channelling: Cutting trenches and clearing masonry channels for utility lines using multi-position Vario-Lock chisel adjustments.

Key Performance & Safety Features

  • Bosch High-Impact Hammer System: Engineered to maximize impact force and energy transfer rate while suppressing internal vibration shockwaves.
  • SDS-max Bit System: Tool-free automatic bit-locking interface ensures secure retention and maximum energy transmission during heavy percussion tasks.
  • Vario-Lock™ Positioning Function: Allows chisels to rotate and lock into 12 distinct working angles to optimize operator posture in tight spaces.
  • Service Minder™ Maintenance Light: Integrated LED indicator alerts operators automatically when carbon brush replacement and service are required.
  • 360-Degree Auxiliary Handle: Fully adjustable side handle rotates completely around the tool body to provide a comfortable grip across any working angle.
