Crush Heavy-Duty Demolition Challenges with the Makita 70 lb. Advanced AVT® Breaker Hammer

The Makita HM1812 is an industrial powerhouse engineered to deliver the hitting force of a pneumatic air hammer without the noise, vibration, or the logistical hassle of a tow-behind compressor. Driven by a high-efficiency 15 AMP motor, this 70 lb. breaker hammer unleashes a massive 53.9 ft.-lbs. (73.8 Joules) of impact energy, making it the premier choice for professional contractors tackling deep concrete removal, trenching, and asphalt breaking. Designed for all-day productivity, the HM1812 eliminates the need for air hoses, providing a plug-and-play demolition solution that outpaces the competition in both speed and convenience.

At the heart of the HM1812 is the latest Advanced Anti-Vibration Technology (AVT®), a synchronized three-component system that reduces vibration to a staggering 6.5m/s². By combining an internal mechanical counterbalance system with a vibration-absorbing housing and fixed rubberized handles, the HM1812 isolates movement away from the user, significantly reducing fatigue and increasing jobsite precision. Advanced features like "Soft no-load" automatically reduce motor speed when not in use to extend tool life, while integrated L.E.D. service lights provide proactive maintenance alerts. Built for the most rigorous environments, this breaker hammer is the ultimate investment for structural demolition and civil engineering projects.

Key Features

  • Unmatched Impact Energy: Efficient 15 AMP motor delivers 53.9 ft.-lbs. of energy to handle the most demanding demolition applications.
  • Advanced AVT® Technology: Synchronized system reduces vibration to a low 6.5m/s² for superior operator comfort and safety.
  • Vibration-Absorbing Housing: The motor and hammer mechanism move independently of the housing to effectively isolate vibration.
  • Soft No-Load Function: Automatically lowers motor speed when idling to increase tool longevity and performance.
  • Service Indicator Lights: Integrated L.E.D. lights notify the user of cord damage or when carbon brushes require replacement.
  • Precision Soft Start: Suppresses start-up reaction for more accurate bit placement and smoother engagement.
  • Heavy-Duty 1-1/8" Hex Shank: Industry-standard bit holder ensures maximum energy transfer and compatibility with a wide range of chisels.

Pro-Tip: To maximize demolition speed, let the weight of the 70 lb. HM1812 do the work rather than leaning into it with your body weight. The Advanced AVT® system is most efficient when the tool is allowed to cycle naturally; forcing the tool can dampen the internal counterbalance system and increase vibration felt in your hands.
