Brushless 28mm delivers high performance with 2.8 joules of hard hitting impact energy. That impact energy allows you to drill holes in masonry up to a 28mm diameter quickly and efficiently. Anti Vibration Technology (AVT) actively reduces the tools vibration through a series of count weight mechanisms and vibration absorbing housing. These designs significantly reducing the vibration transferred to the user for more comfortable use of the tool over extended periods of time. Compatible with AWS* the HR001G can be paired with a compatible vacuum for on demand dust extraction. AWS uses Bluetooth to wirelessly power on and off the extraction unit using the tools trigger. *AWS receiver sold separately In addition the HR001G is compatible with a wide variety of optional dust management options including the onboard dust extraction system DX12.
