With a total length of only 100 mm, the DeWalt DCF850NT 1/4" cordless impact driver can be used without difficulty even in very tight spaces. The robust 1/4" internal hex driver with self-locking mechanism and ejection function enables quick and easy bit changes. The DCF850NT also features electronic 3-stage speed and stroke control, a large, easy-to-adjust switch, and a robust aluminum hammer housing. Even darker work areas are no problem, as the built-in, very bright LED ring illuminates even the darkest corners with three powerful LEDs. The ergonomic, rubberized handle provides effective vibration damping and comfortable handling. The DCF850NT comes standard with a T-STAK box and as a base model (without batteries and charger), making it ideal for use with existing 18.0V XR batteries or the DEWALT "Battery Plus" system.
