The 80V max (40V max X2) XGT® Brushless 28 lb. Demolition Hammer Kit (GMH02PM) is a cordless concrete solution designed for heavy-load applications. It delivers the power, speed, and run-time for corded demands, without the cord. The demolition hammer delivers up to 15% faster breaking than equivalent corded hammer (HM1213C). It accepts SDS-MAX bits.

Anti-Vibration Technology (AVT®) for reduced vibration. More than just a padded handle, AVT is an internal counterbalance that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. For added durability in harsh job site conditions, Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance.

Auto-Start Wireless System (AWS®) uses Bluetooth® technology for wireless power-on and power-off communication between the equipped tool and dust extractor. Once connected via AWS, the AWS-equipped dust extractor will automatically power on or off when the AWS-equipped cordless tool starts or stops, running only when the tool is in use. This increases productivity on a single charge and reduces continuous noise at the job or work site.

Constant speed control that automatically applies additional power to the motor to maintain speed under load to complete challenging jobs and a variable speed control dial enables users to match speed to the application. Additional performance features include an electric brake, variable speed dial, built-in L.E.D. light, a soft-start to suppress start-up reaction, and Soft No-load function that automatically reduces the speed of the motor when idling.

XGT is a system of equipment, tools, batteries and chargers utilizing 40v max lithium-ion batteries. XGT is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site. XGT is equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability features to outpower, outsmart and outlast the rest.

  • XGT®
  • XGT® is a new 40V | 80V max system of cordless equipment and tools. XGT outpowers, outsmarts, and outlasts the rest. Through Makita’s innovative engineering, the technology within XGT will lead to creating the equipment and tools of the future [Learn More]

  • AWS®
  • Makita takes another step toward a truly cordless job site with Auto-Start Wireless System. AWS® uses Bluetooth® technology for wireless power-on and power-off communication between the equipped tool and dust extractor. AWS® is intelligent communication that eliminates cords and excessive noise since the dust extractor runs only when trigger-activated by an AWS® tool. When the trigger is released, the dust extractor powers-down. The Makita AWS® dust extractor (XCV08Z) is powered by two 18V LXT® batteries for maximum performance, and users benefit with an expanding AWS® system that includes cordless tools for concrete, metal and woodworking.

  • XPT™ Extreme Protection Technology
  • When the job takes your Makita tool into harsh conditions, Makita Extreme Protection Technology (XPT™) provides added protection. XPT™ is a series of integrated seals engineered to channel away dust and water for increased durability. Wherever the job takes you, Makita tools equipped with XPT™ are engineered for increased durability and longer tool life.

  • AVT® Anti-Vibration Technology
  • Anti-Vibration Technology (AVT®) is a counterbalance system inside the tool that significantly reduces vibration. The AVT® counterbalance design is based on seismic engineering, which developed this damping science to absorb shocks and protect buildings from earthquakes. AVT® uses a mechanical damper, effectively a counterbalance weight inside the tool, that provides an equal and opposite force that puts a mass directly opposite the point where the striker bolt delivers the impact. As vibration is eliminated, power is efficiently increased which allows more of the generated energy in the motor to be delivered to the tool bit. Makita also has an AVT® counterbalance system in select recipro saws. For users, AVT® means significantly less vibration with no compromise in power and performance. [Learn More]
