Description
Corded demolition hammers tether operators to noisy generators during critical structural concrete repairs on elevated bridges. The Bosch PROFACTOR 18V Hitman Connected Ready SDS max 1-7/8 inch rotary hammer kit delivers corded-equivalent power with pure cordless freedom. An 18-volt brushless motor generates 9.3 foot-pounds of impact energy. Pushing SDS-max core bits beyond four-inch diameters will trip thermal safety limits.
Die-cast magnesium gearboxes house a heavy electro-pneumatic striker assembly supported by double-row cylindrical bearings. The brushless motor wet-end pairs with high-output battery architecture to deliver extreme wattage without thermal motor trip events. KickBack Control accelerometers decouple the mechanical drive within milliseconds if the bit snags on heavy reinforcement steel. An SDS-max drive chuck uses cryogenically treated alloy steel wedges to transfer rotational torque and impact shock.
Hitman Rotary Hammer Hardware Specs
Massive pneumatic strikers pulverize heavy aggregate for fast anchor placement and concrete demolition. Electronic user interfaces display real-time tool operational status and battery charge levels.
- 1.875-inch solid bit capacity drills heavy structural foundation anchors effortlessly
- 9.3 foot-pounds of impact energy pulverizes hard aggregate during heavy demolition runs
- Brushless 18-volt motor platform provides corded-grade power with total jobsite mobility
- Vibration Control handle suspension reduces reciprocating shock on technician joints
- KickBack Control technology cuts motor power instantly if bits bind on embedded rebar
- Interactive tool display screen provides real-time feedback on battery and thermal status
- SDS-max chuck mechanism locks heavy drilling bits and chisels without hand tools
Dyno Bench Load Telemetry
Bench load testing evaluates electrical current draw and impact cadence through high-strength structural concrete. Unloaded motor rotation draws 3.4 amperes from the 18-volt battery, surging to 38.6 amperes while drilling 1-3/4-inch holes. Pack terminal voltage drops to 15.3 volts during continuous heavy hammering. The striker delivers 2900 BPM under forty pounds of operator downforce. Sound meters capture 96 dBA at operator ear level. Gearcase exterior temperatures climb 33 degrees Fahrenheit after ten holes.
Field Service Operational Traps
Dry concrete dust packs inside the SDS-max chuck cavity if technicians skip bit shank lubrication. Finish carpenters hanging interior doors have no need for this heavy demolition hammer. Never operate this high-impact hammer without checking side handle clamp tightness.
- Grease bit shanks with high-pressure chisel lubricant before inserting into the chuck.
- Wipe abrasive concrete powder off the rubber chuck seal sleeve after every shift.
- Blow dry compressed air through motor intake vents every forty hours of run time.
