DeWalt DCF961B 20V MAX Impact Wrench vs DeWalt DCF923B Atomic 3/8 in. Impact Wrench

Buy the DCF961B if you loosen rusted lug nuts, pipe flanges or concrete anchors; its 1,200 ft-lbs of fastening torque and roughly 1,750–1,900 ft-lbs of breakaway torque put it in a different class. Buy the DCF923B for engine bays, suspension work and light assembly, where its compact 3/8-inch body and 4 speed settings plus Timber Screw mode fit spaces the big tool cannot reach. The DCF961B is heavy at about 7.65–8.45 lbs and needs a high-output battery to show its full power; the DCF923B is the easier tool to live with day to day. Owners rate the smaller DCF923B higher (4.8 vs 4.4), but that reflects its narrower, easier job, not more muscle.

• Choose the DCF961B if you need maximum breakaway torque for seized lugs, flange bolts or anchor bolts and can carry a heavier tool.
• Choose the DCF923B if you work in tight engine bays and on 3/8-inch fasteners and want a light, compact wrench with fine speed control.
