Our take on the DeWalt DCF900B 20V MAX XR 1/2" Impact Wrench

The DeWalt DCF900B is a 1/2-inch cordless impact wrench in DeWalt's 20V MAX XR line. It delivers 1,030 ft-lbs of fastening torque and 1,400 ft-lbs of breakaway torque, putting it among the strongest 1/2-inch impact wrenches in its class. A 4-mode speed selector and Precision Wrench control help prevent overtightening and fastener run-off. At 6.4 lbs (bare tool), it is heavier than compact rivals, but that weight comes with power that can loosen stubborn bolts. It suits mechanics and tradespeople who need maximum torque without a cord, and it is sold as a bare tool, so batteries and charger are extra.
