TE 70-ATC/AVR is an exceptionally powerful rotary hammer drill for heavy-duty concrete construction work. Ergonomics were the central design consideration: how to make a tool with 11.5 joules of impact energy comfortable and easy to control. The strategy focused on re-engineering the chassis to get the total weight below 9.5 kg and vibration below 10 m/s² – a breakthrough for any tool in this top power class. Decoupled handles dampen vibrations reaching the user’s arms, making the TE 70-ATC/AVR suitable for more precise, safer handling for longer times. Redesigned contours around the housing and grips offer firm handholds for more working positions.
