The DeWalt DCF900B is a 20V MAX cordless impact wrench built for heavy fastening: 1,030 ft-lbs of fastening torque and 1,400 ft-lbs of breakaway torque, with 2,300 RPM and 2,200 impacts per minute. It adds four speed modes, a variable-speed trigger and Precision Wrench control to limit overtightening and fastener run-off. At 6.4 lbs and 8.8 inches long it is a full-size, high-torque tool, heavier than compact mid-torque wrenches but in the same class as other premium high-torque cordless models. It suits mechanics and tradespeople loosening rusted bolts and driving large fasteners; the bare tool ships without a battery or charger, so it fits buyers already on the 20V MAX platform.

Rated 4.4 out of 5 from 157 ratings. Owners value the torque for breaking loose rusted and stubborn fasteners, and the speed settings give useful control. The main complaints are the weight and size, and that it arrives as a bare tool.
