Authorized Dealer Badge DEWALT logout

Loosen Seized Structural Fasteners Up to 15% Faster and Protect Battery Connections with Active Shock Absorption

The DEWALT DCF900H1 20V MAX* XR® 1/2-Inch High Torque Cordless Impact Wrench Kit is an industrial-grade mechanical fastening system engineered to deliver up to 1,030 foot-pounds of maximum fastening torque and 1,400 foot-pounds of maximum breakaway torque. Powered by a high-efficiency brushless motor and a 5.0Ah POWERSTACK™ stacked pouch cell battery, this heavy-duty tool replaces traditional pneumatic lines to clear stubborn, rusted bolts across structural installations. Outfitted with a rapid-change 1/2-inch hog ring friction anvil, a 4-mode speed drive system, and proprietary Precision Wrench™ microprocessor control, this portable impact assembly maximizes solo field productivity while stopping hardware runoff.

Best Used For:

  • Heavy Mechanical Equipment Overhauls: Extracting corroded, large-sized pipe flanges, grooved utility couplings, and high-tensile industrial commercial vehicle wheel lugs unassisted.
  • Structural Concrete Anchor Bolt Setting: Driving large screw anchors and structural fastening rods down directly into aggregate masonry foundation pads without power drops.
  • High-Volume Fleet Maintenance: Executing repeating socket adjustments across multi-axle machinery setups using an open friction ring path that accelerates tip swaps.

Key Performance & Safety Features

  • 1,400 Ft-Lbs Industrial Breakaway Torque: High-output brushless motor channels severe fluid energy to break loose frozen, rust-welded fasteners up to 15% faster.
  • Precision Wrench™ Multi-Mode Protection: Smart drive integration limits forward rotational speeds to stop overtightening and curbs reverse speeds to capture loose nuts safely.
  • BatteryGuard™ Vibration Isolator: Integrated shock-absorbing mechanical link dampens incoming impact harmonics to protect internal battery cell contacts from premature failure.
  • POWERSTACK™ Stacked Pouch Cells: Advanced battery architecture delivers increased power density, low internal resistance, and prolonged lifecycle metrics under extreme tool loads.
  • Hog Ring Friction Ring Anvil: Solid 1/2-inch square driver face allows professional trade workers to pop thick impact sockets on and off effortlessly without separate pin tools.

PRO-TIP: When seating thick-walled 1/2-inch impact sockets onto the hog ring anvil, press the accessory down flat until the friction ring compresses fully behind the internal socket detent groove. Keeping this connection flush seals the tool face and allows the full force of the 1,400 ft-lbs breakaway torque to exit cleanly into the frozen bolt head.
