70 lb. Advanced AVT® Breaker Hammer, accepts 1‑1/8" Hex bits
70 lb. Advanced AVT® Breaker Hammer
  • COMFORT : Mechanical counterbalance system greatly reduces vibration, resulting in a low 6.5m/s2
  • CONTROL : Vibration absorbing housing moves independently of the motor and hammer mechanism
  • DESIGN : L.E.D. power & service light indicates cord failure or brush replacement warning
  • CONVENIENCE : 16.4 ft. power cord and integrated cord guide which positions the power cord away from working area
  • INCLUDES : Hex wrench

The new 70 lb. AVT® Breaker Hammer (model HM1812) is engineered to hit like an air hammer, but with less noise and vibration. It has a powerful 15 AMP motor that delivers a full 53.9 ft.lbs. (73.8 Joules) of impact energy, so contractors get hard-hitting performance. Users also benefit from less noise and lower vibration than an air hammer, and zero hassle with an air hose and compressor. The HM1812 features the latest Advanced AVT® Technology, a synchronized three-component system that more effectively reduces vibration. The internal mechanical counterbalance system, vibration-absorbing housing, and fixed movement handles are engineered for significantly less vibration during concrete breaking applications.

  • Efficient 15 AMP motor with improved hammer mechanism delivers 53.9 ft.lbs./72.8 joules of impact energy to handle the most demanding applications
  • Advanced AVT® is a synchronized, three-component system that more effectively reduces vibration in varying conditions resulting in a low 6.5m/s2
  • Advanced AVT® provides a mechanical counterbalance system which greatly reduces vibration and directs more impact energy to the work surface for increased user comfort and greater productivity
  • Advanced AVT® provides a vibration absorbing housing which moves independently of the motor and hammer mechanism effectively isolating more vibration away from the user
  • Advanced AVT® provides rubberized fixed handles which dampen vibration for increased comfort and precision
  • Soft start is designed to suppress start-up reaction for greater accuracy on start up
  • "Soft no-load" function automatically reduces the speed of the motor when not in use which helps increase tool life and performance
  • L.E.D. power light indicates switch failure or cord damage
  • L.E.D. service light notifies the user approximately 8 hours before brushes need to be replaced
  • Automatic brush cut-off protects commutator from damage for longer tool life
  • Cylindrical bit holder allows for the bit holder assembly to be re-positioned should the original bolts and bolt holes become damaged
  • Recessed lifting handles provide more convenience
  • Breaker includes a 16.4 ft. power cord and integrated cord guide which positions the power cord away from working area
AVT Advanced (Color on White)
  • Advanced AVT®
  • Advanced AVT® enhances Makita Anti-Vibration Technology (AVT®) with a 3-component system that sets new standards in vibration reduction, with no compromise in performance. The Air Actuated Counterbalance moves counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. The Vibration Absorbing Housing isolates the rear and side handle, reducing vibration for the user. And the Integrated Damper Spring is engineered to absorb impact vibrations from the drill bit.
