The DEWALT 20V MAX* XR® 1/2 in. High Torque Impact Wrench delivers up to 1,320 ft-lbs of max fastening torque and 1,900 ft-lbs of max breakaway torque using the DCBP520 battery, representing the highest-rated cordless 1/2 in. impact wrench in its class. Glass-filled nylon housing protects against oils and solvents. Precision Wrench mode prevents overtightening and fastener run-off. A 4-mode push-button switch adjusts speed and LED brightness. This bare-tool listing ships without battery or charger.
Can the DCF961B remove bolts that a standard 1/2 in. impact wrench cannot?
Yes. Reviewers report removing bolts on passenger cars that a torch and breaker bar could not budge, as well as handling most semi-truck lug nuts in daily use. The 1,900 ft-lbs breakaway torque gives it significantly more starting force than lower-tier 20V wrenches.
How does the DCF961B's torque compare to the DCF900?
The DCF961B delivers 1,320 ft-lbs fastening torque vs 1,030 ft-lbs for the DCF900 — a 28% increase when using the DCBP520 battery. Breakaway torque is 1,900 ft-lbs vs 1,400 ft-lbs.
Is the DCF961B practical for use under vehicles in tight engine bays?
The tool is heavy at 8.75 lbs and 11 inches wide, which limits access in tight engine compartments. Reviewers note it works well for wheel and suspension work but is difficult to maneuver into confined engine areas where a compact ATOMIC wrench would be preferable.
What battery is recommended for maximum torque output?
DEWALT specifies 1,320 ft-lbs fastening torque using the DCBP520 POWERSTACK battery. Using a standard DCB205 5.0 Ah battery still delivers strong performance but at a lower peak torque rating.
Does the glass-filled nylon housing provide meaningful protection in shop environments?
Yes. The housing is specifically designed to resist oils and harmful solvents commonly found in automotive and industrial shops, helping extend tool life compared to standard nylon housings.
