DEWALT Impact Wrench DCF900H1 20V 1/2 Inch High Torque Cordless Driver Kit

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.
