The DEWALT DCF921B ATOMIC 20V MAX is a compact cordless 1/2 in impact wrench for automotive, construction and mechanical fastening work. It delivers up to 300 ft-lbs of maximum fastening torque and 450 ft-lbs of maximum breakaway torque. That is enough to install and remove bolts, lug nuts, anchors and other demanding fasteners. Its compact size helps in tight and hard-to-reach spaces.
The wrench has 4 speed settings, including Precision Wrench and Timber Screw modes. Precision Wrench helps prevent overtightening in forward and fastener run-off in reverse. Timber Screw mode optimizes speed for large wood fasteners. The 1/2 in hog ring anvil allows quick, secure socket changes.
An integrated LED work light with brightness control lights up the area around the fastener. The housing is glass-filled nylon, which helps resist damage from exposure to select oils and solvents. A belt clip is included. This is a bare tool, sold without a battery or charger, and it works with DEWALT 20V MAX batteries and chargers.
