Makita has added a new breaker to its range of 80VMax XGT machines. The HM004G, as it is memorably titled, matches the equivalent corded model, although with the flexibility, safety and convenience of cordless power.
The HM004G delivers 72.8 joules of impact energy at a rate of 870 blows per minute. It is powered by two Makita 40VMax XGT batteries and in addition to breaking, chipping and channelling with the 28.6mm hex chisel, it can also be used for trenching by attaching a clay spade or for compacting soil with a rammer fitted.
The HM004G also features Makita’s anti-vibration technology, which reduces the vibration transferred from the tool to the user’s hands and arms and extends the length of time that users can comfortably operate the tool. To achieve this, the tool has been designed with a counterweight mechanism that offsets the force of the machine and a vibration absorbing housing in the body of the breaker that further reduces the vibration experienced by the user. As a result, the HM004G achieves a vibration level of just 6.5 m/s², which is 30% lower than the previous generation of equivalent corded breaker.
Brushless motors use electromagnetism to rotate the motor and drive the action of the tool, eliminating friction and wasted energy. A brushless motor can produce more torque, allowing the same results while using less power - run times can be extended by up to 50% per battery charge for improved productivity and fewer recharges.
Makita’s Auto-Start Wireless System is also included, which connects the HM004G to compatible dust extractors, such as the 80VMax (40Vx2) VC006 M-Class Dust Extractor, via Bluetooth to run the dust extractor automatically when the tool is in use, making dust management simpler.
Lastly, the HM004G features soft start and anti-restart functions for improved safety, as well as twin LED job lights for better visibility of the work area.
