HEAVY DUTY BREAKER

Makita HM1812 AVT Electric Breaker: Class-Leading Demolition Power with Advanced Anti-Vibration Technology

The Makita HM1812 AVT Electric Breaker is a heavy-duty, professional-grade demolition hammer designed for the most demanding breaking and chiselling applications in concrete, asphalt, and masonry. As a 30kg class breaker, it sets industry benchmarks with its exceptional impact energy combined with Makita's innovative Anti-Vibration Technology (AVT), providing powerful demolition capabilities while significantly reducing user fatigue and increasing usable work time.

Features

• Massive Impact Energy (72.8 - 73 Joules EPTA-Procedure 05/2009): Delivers best-in-class hitting power, allowing for rapid and efficient breaking of concrete, asphalt, and heavy masonry, making it ideal for large-scale demolition.
• Powerful 1,700W (110V) / 2,000W (240V) Motor: A robust motor provides consistent and high performance under heavy loads, ensuring the tool maintains its breaking power throughout demanding tasks.
• High Blows Per Minute (870 BPM): The optimized impact rate ensures rapid material removal for increased productivity.
• Advanced Anti-Vibration Technology (AVT): This is a hallmark feature of the HM1812, employing a synchronized three-component system to effectively reduce vibration:
  • Vibration Absorbing Housing: The main handle section is effectively isolated from the motor and hammer mechanism by vibration-absorbing springs.
  • Counterweight Mechanism: An internal counterweight moves in the opposite direction to the piston, actively reducing dynamic vibration generated during chipping.
  • Damping Spring: An integrated damper spring is engineered to absorb impact vibrations from the chisel bit. This combined system results in an exceptionally low vibration level, leading to significantly extended trigger time for operators before reaching exposure limits.
• "Soft No-Load" Function: Automatically reduces the motor speed when the tool is idling (not under load). This feature suppresses machine body vibration when not in use, making the tool more comfortable to handle between breaking intervals and reducing wear.
• Soft Start Function: Ensures smooth and controlled start-ups, preventing sudden jolts and allowing for more accurate chisel placement.
• Constant Speed Control: Maintains consistent speed under load, ensuring maximum power delivery even when working on challenging materials.
• 1 1/4" (28.6mm) Hex Shank Tool Holder: Compatible with standard 1 1/4" hex chisel bits, providing versatility and ease of accessory change. The cylindrical bit holder design allows for re-positioning if bolt holes become damaged.
• LED Service Light & Power Indicator:
  • Service Light: Notifies the user when carbon brushes are nearing the end of their life (typically around 8 hours before replacement is due), allowing for proactive maintenance and preventing unexpected downtime.
  • Power Light: Indicates that the tool is connected to the power supply.
• Ergonomic Soft Grip Handles: Provide a comfortable and secure grip, enhancing control and reducing fatigue during long periods of operation. The handles are fixed movement, designed for optimal control and accuracy
• Highly Durable Switch: Engineered for robustness and longevity to withstand the demands of heavy-duty demolition.
• Recessed Lifting Handles: Provide convenient hand-holds for easier lifting and transport of the heavy tool.
• Dust Extractor Connectable: Designed to be compatible with Makita dust extraction systems (via optional accessories) for improved health and safety on site, reducing airborne dust.
• Optional Hammer Trolley: Can be used with the Makita D-54972 Hammer Carrier Trolley for easier transport around the job site.
• Double Insulation: Provides an essential layer of protection against electrical shock, enhancing user safety.
