DeWalt DCF961B 20V MAX Impact Wrench vs DeWalt DCF911B 20V Impact Wrench

The DCF961B is the heavy-duty tool: 1,200 ft-lbs fastening torque, 1,750–1,900 ft-lbs breakaway, three speed settings and Precision Wrench mode. The DCF911B is a compact mid-torque wrench at roughly 2.3 lbs with 250 ft-lbs fastening and 400 ft-lbs breakaway, so it handles lug nuts and light bolts without wearing you out. Owners of the big DeWalt rate its power highly but note the weight and that it ships bare. The DCF911B scores slightly higher with owners for everyday usability. Buy the 961 for seized bolts, pipe flanges and anchor setting; buy the 911 for tires, lawn equipment and general assembly.

• Choose the DCF961B if you need maximum breakaway power for rusted or large fasteners and already own 20V MAX batteries.
• Choose the DCF911B if you want a light, one-hand wrench for lug nuts and routine bolting and value the included 5Ah battery.
