The DeWalt DCF923B is a compact 20V MAX cordless impact wrench with a 3/8-inch square drive and a brushless motor. It delivers up to 450 ft-lb of fastening torque and 3,200 impacts per minute in a body just 5 inches long, which lets it reach fasteners that full-size wrenches cannot. It is sold as a bare tool, so it runs on DeWalt's 20V MAX lithium-ion batteries you already own. It suits mechanics and DIYers who want a light, short wrench for engine bays, suspension and lug nuts, and it competes with other compact 3/8-inch impact wrenches on size and torque rather than on included batteries or accessories.

The DeWalt DCF923B is a cordless compact impact wrench from the 20V MAX ATOMIC line. It has a 3/8 inch square drive and a brushless motor. It is sold as a tool only.
It delivers 300 ft-lbs of tightening torque and more than 450 ft-lbs of breakaway torque, so it can be used for a range of construction and automotive work. It weighs 2.4 lb and is under 5 inches long, which helps reduce fatigue and lets it reach tight spaces.
The wrench has variable speed, a forward and reverse switch, and an LED light. A precision wrench control mode helps prevent overtightening and run-off of fasteners when selected.
