Latest generation of powerful 4-stage cordless impact wrench (including one control stage) with lightweight and compact dimensions. Longer runtime per battery charge and increased lifespan thanks to innovative brushless motor technology. Speed and impact rate, as well as torque strength, can be electronically regulated in 3 stages via a finely adjustable throttle switch, providing maximum control for all applications. Additionally, the electronic control stage stops the clockwise rotation as soon as the screw makes contact with the material, regulating the speed and impact rate to prevent unintentional over-tightening of the screw or damage to the material. In counter-clockwise rotation, the speed is reduced once the screw is safely removed without the aid of the impact mechanism. All 4 stages can be quickly and securely adjusted electronically via a switch. Ideal for extremely heavy screwing tasks due to a very high tightening torque of over 800 Nm and a loosening torque of nearly 1,100 Nm. Trouble-free long-term use is ensured by safety electronics (permanent monitoring of battery temperature, current draw, and discharge protection). The high-quality and robust aluminum impact housing allows for optimal heat exchange, thus increasing the device's lifespan. Sturdy ½” external square drive with detent or HOG ring for quick changes and secure fit of the tools. Perfect handling due to the extremely compact and lightweight design, as well as ergonomically rubberized grip areas. With a total length of just 175 mm, it can be easily used in confined spaces. Very powerful and individually adjustable LED for optimal visibility at the workplace. Easy to use with a robust metal belt hook. Compatible with all 18 Volt XR or XR Flexvolt batteries (not included).
