High Torque Sub Compact Brushless Performance for Restricted Engine and Suspension Bays

The DEWALT DCF901B XTREME 12V MAX Brushless 1/2-Inch Cordless Impact Wrench is a sub-compact battery-powered fastening tool engineered to deliver up to 400 ft-lbs of maximum breakaway torque and 250 ft-lbs of tightening torque. Operating at a maximum speed of 2,850 RPM, this lightweight handheld power wrench utilizes an efficient brushless motor to remove frozen structural fasteners and automotive wheel lug nuts cleanly. The mechanical layout features a short front-to-back framework, a 1/2-inch hog ring anvil for rapid socket changes, a chemical-resistant glass-filled nylon chassis, and an integrated 360-degree LED lighting ring to maximize visibility in close quarters.

**Battery and charger sold separately.

Best Used For:

  • Suspension Bolt Removal: Breaking loose rusted, seized control arm bolts, shock tower hardware, and stabilizer bar link brackets.
  • Automotive Wheel Service: Zipping off tight, high-torque passenger vehicle lug nuts rapidly on mobile tire carts or garage service racks.
  • Cramped Engine Assemblies: Accessing hard-to-reach motor mounts, accessory bracket fasteners, and transmission casing bolts inside tightly packed vehicle bays.

Key Performance & Safety Features

  • Sub-Compact Powertrain: High-efficiency brushless system provides structural 18V-class torque output within an ultra-short, highly agile 12V tool profile.
  • 360 Degree LED Light Ring: Nose-mounted circular lighting cluster illuminates darkened undercarriages and machinery frames without creating unwanted shadows.
  • Hog Ring Socket Retainer: Heavy-duty 1/2-inch square hog ring anvil friction-fits impact sockets securely while enabling rapid, tool-free manual swap-outs.
  • Chemical Resistant Barrier: Structural glass-filled nylon housing guards internal electronics against degradation from motor oils, transmission fluids, and shop solvents.
  • Variable Speed Control: Fine-tuned mechanical trigger matches rotational kinetic energy closely to individual fastener diameters to help prevent thread stripping.

What's Included

  • (1) DEWALT DCF901B 12V MAX Brushless 1/2-in. Impact Wrench (Bare Tool)
  • (1) Belt Hook
