Why it ranks #1: Its stated 1,400 ft-lbs of breakaway torque and 1,030 ft-lbs of fastening torque suit demanding automotive fasteners; four modes add control.

A listed 1,400 ft-lbs of breakaway torque gives the DEWALT DCF900B a clear role in demanding automotive fastening, including stubborn wheel hardware. Four speed modes, a variable-speed trigger, and Precision Wrench control let users tailor operation, while an on-tool LED helps illuminate darker work areas.
