TL;DR Strong community fastener-removal record on a ½" drive · corroded axle bolts and caliper brackets with Loctite without stalling. DeWalt 20V MAX XR platform; no US independent safety certification on file.
The DCF900B is a cordless ½" drive impact wrench rated at 1,030 ft-lbs fastening torque, running on DeWalt's 20V MAX XR platform with a brushless motor and four torque modes. No independent torque meter test has been located; community evidence is fastener-removal outcomes only · multiple purchasers confirm removal of heavily corroded axle bolts and caliper brackets without stalling. At 6.4 lbs bare tool, owners consistently note it as heavy for extended overhead use.
Mechanics already on DeWalt's 20V MAX platform who need reliable high-torque removal · wheel studs, suspension bolts, agricultural fasteners · will find this wrench platform-convenient and capable. Skip it if weight matters for repeated overhead tire changes; a lighter ½" model in the same ecosystem serves that use better.
No US independent safety certification confirmed. Li-ion battery · dispose via Call2Recycle. Hearing protection appropriate for extended use.
No. The DCF900B is the bare-tool variant · it includes the wrench only. Battery and charger are sold separately. The wrench is compatible with all DeWalt 20V MAX batteries, including XR and FLEXVOLT packs.
No US independent safety certification has been confirmed. The UL Product iQ and Intertek ETL lookups were not completed due to database access constraints; CE status is also unverified as of 2026-05-31. The health score reflects a certification deduction from the 9.0 electronics base.
No independent calibrated torque meter test has been located for the DCF900B as of 2026-05-31. Community evidence is fastener-removal outcomes only: multiple purchasers confirm removal of corroded axle bolts, caliper brackets with Loctite, rusted O2 sensors, and tractor fasteners without stalling. The manufacturer rates the tool at 1,030 ft-lbs fastening and 1,400 ft-lbs breakaway torque.
Amazon currently lists this as an Add-On item, which means it must be purchased alongside a qualifying order to check out. If you're seeing a cart restriction, add another item to meet the order minimum, or check if a kit version (DCF900P2 or similar) is available without the Add-On restriction.
