Longer running time per battery charge and extended service life thanks to innovative brushless motor technology. Speed, stroke rate, and maximum torque are electronically adjustable in two steps for perfect control in all applications. An additional electronic control stage (with the same maximum values as in stage two) minimizes the risk of overtightening the thread in clockwise rotation and reduces the maximum speed in counterclockwise rotation once the screw has been loosened. It features a very high torque of almost 450 Nm for extremely heavy screwdriving work. The easy-to-dose switch electronics allow for precise screwdriving work. Long-term use is problem-free due to safety electronics that permanently monitor battery temperature, current consumption, and discharge protection. The robust aluminum impact mechanism housing enables optimum heat exchange, increasing the service life of the device. A robust 1/2" external square socket with ball catch guarantees a secure fit of the insert tools even when screwing hard. Optimally positioned and powerful LED lights provide perfect visibility at the workplace. The device offers perfect handling due to its extremely compact and lightweight construction, along with ergonomically rubberized grip areas. It is easy to use thanks to a robust metal belt clip. Compatible with all 18.0 Volt or 54.0 Volt Flexvolt XR batteries in any Ah class (not included). Standard in T STAK box and as a basic type (without batteries and charger), it is optimally suited for existing 18.0 Volt XR batteries or for the DeWALT "Akku Plus" system.
