The DeWalt DCF845B is a brushless 20V MAX XR impact driver with a 1/4-inch hex quick-release chuck, three speed settings and a variable-speed trigger. Its brushless motor is rated at 1,825 in-lbs of torque and up to 3,400 rpm, roughly 30% more torque than the model it replaced, which puts it among the stronger 18V-class impact drivers. A three-LED ring light, a belt hook and a three-year limited warranty round it out. It is sold as a bare tool, so batteries and a charger are not included. It suits tradespeople and serious DIYers who already own DeWalt 20V MAX batteries and want a compact driver for framing screws, decking and heavy fastening.
