Designed with a hog ring insert on the square drive to allow for easy changing of sockets where various sizes of bolts may need to be installed or removed. Should you be working at heights, or only require a single sized socket for the job, a pin detent type impact wrench will be better suited. However, if you need that efficiency, versatility and quick adaptability, then this is the impact wrench for you. Further than that, it includes all of the features that you will have come to expect from anything in the DeWalt brand: a light and compact design, a variable trigger for full control, a brushless motor for excellent energy transfer and battery life, an LED joblight and a comfortable rubber XR grip to reduce fatigue over prolonged usage.
