The Makita HM001G 40V Max XGT Brushless Demolition Hammer from Dax Tools is a Powerful Cordless unit Powered by a 40V Max XGT Battery and designed to match the Working capabilities of a Mains Powered equivalent unit. The HM001G incorporates AWS Auto-Start Wireless System, which allows a Bluetooth connection to Work alongside a compatible Dust Extractor. The Dust Extractor switches on automatically when the trigger is pulled. With constant speed control, an anti-vibration housing and a Compact design, the HM001 will reduce operator fatigue easily as the weight, vibration control and speed control help with this. The Demolition Hammer also incorporates a "Soft no load" function which automatically reduces the motor speed during idling to suppress the vibration of the machine Body, as well as a 5-stage Max speed selection. The 12x bit Angle settings and the lock-on/lock off features are also included. The Brushless motor, along with the 40V Max XGT improves the efficiency of the demolition Hammer and reduces the risk of continuous servicing. At the heart of this machine is the Brushless motor that allows you to use the tool efficiently. As part of the design, the tool utilizes every bit of Battery Power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and Working more efficiently. The technology in creating a Brushless motor system allows for perfect symmetry between Battery Power and usage ensuring you get all the Power you need, when you need it.
