The DEWALT DCF921B is a cordless impact wrench with a 1/2 inch drive. It delivers up to 300 ft-lbs of maximum fastening torque and 450 ft-lbs of maximum breakaway torque.
It has four speed settings, and precision wrench control helps prevent overtightening and fastener run-off. A timber screw mode optimizes speed in wood. The hog ring anvil allows quick, secure socket changes. An onboard LED with brightness control lights dark workspaces.
The housing is glass-filled nylon, which resists damage from some oils and solvents. The tool runs on a 20V MAX lithium-ion battery. It is sold as a bare tool, so the battery and charger are not included.
