Description

DeWalt DCF964B 20V MAX XR 3/4″ Brushless High Torque Impact Wrench with Hog Ring Anvil – Tool Only

Industrial Might. Unmatched Breakaway Power.

The DeWalt DCF964B 20V MAX XR® 3/4-Inch High-Torque Impact Wrench* is engineered for the heavy-duty professional who refuses to be tethered to a compressor. Delivering a staggering 1,200 ft-lbs of max fastening torque and a massive 1,900 ft-lbs of breakaway torque, this tool is purpose-built for the largest fasteners found on jobsites today. From bridge work to oil and gas maintenance, the DCF964B provides the "nut-busting" force required for seized, rusted, or massive structural bolts.

Equipped with a high-efficiency XR® Brushless motor, this 3/4" powerhouse features a 4-mode push-button selector for precise control over various applications. The integrated Precision Wrench™ technology helps prevent over-tightening in forward and provides controlled speed in reverse to prevent fasteners from flying off at height. With a glass-filled nylon housing designed to resist harsh jobsite chemicals and a bright, adjustable LED, the DCF964B is as smart as it is strong.

Why the DeWalt DCF964B XR is the Ultimate Industrial Choice:

  • 1,900 ft-lbs Breakaway Torque: The most powerful 20V MAX* impact wrench in the DeWalt lineup, designed for industrial-scale fastening.
  • 3/4" Hog Ring Anvil: Optimized for high-torque transfer and fast, one-handed socket changes for improved productivity.
  • 4-Mode Speed Settings: Easily toggle between speeds and specialized modes to match the torque requirement of the task.
  • Precision Wrench™ Mode: Advanced electronics protect your work by pausing before impacting in forward and slowing down once the bolt is loose in reverse.
  • Jobsite Tough: Features a rugged housing and a comfortable over-mold grip to reduce vibration during long demolition or assembly shifts.

Frequently Asked Questions

+ When should I use a 3/4" drive instead of a 1/2" drive?
The DCF964B 3/4" is designed for larger fasteners (typically 1-1/8" and up) where 1/2" anvils risk snapping under extreme torque. The larger 3/4" anvil provides a much larger surface area to transfer the massive 1,900 ft-lbs of torque safely.
+ Which battery provides the most power for this tool?
To achieve the maximum rated torque, we recommend using FLEXVOLT® 9.0Ah or 12.0Ah batteries, or POWERSTACK™ 5.0Ah batteries. These packs provide the high-current discharge required by the motor to hit 1,900 ft-lbs.
+ Is the 3/4" anvil compatible with 1/2" sockets?
No. You must use 3/4" drive impact-rated sockets. Using adapters to downsize to 1/2" sockets is dangerous, as this tool will likely shatter 1/2" accessories instantly.
+ What is the best application for this tool?
This tool is the "Gold Standard" for heavy equipment repair, structural steel bolting, agricultural maintenance, and oil/gas industry work where large-diameter fasteners are common.
