Our take on the DEWALT DCF900B 20V MAX Brushless High Torque Impact Wrench

The DeWalt DCF900B is a 20V MAX cordless impact wrench built for heavy fastening: 1,030 ft-lbs of fastening torque and 1,400 ft-lbs of breakaway torque, with 2,300 RPM and 2,200 impacts per minute. It adds four speed modes, a variable-speed trigger and Precision Wrench control to limit overtightening and fastener run-off. At 6.4 lbs and 8.8 inches long it is a full-size, high-torque tool, heavier than compact mid-torque wrenches but in the same class as other premium high-torque cordless models. It suits mechanics and tradespeople loosening rusted bolts and driving large fasteners; the bare tool ships without a battery or charger, so it fits buyers already on the 20V MAX platform.

Best forAuto mechanics working on suspension, hubs and rusted boltsTradespeople driving large lag bolts and structural fastenersOwners already on the DeWalt 20V MAX battery platformHeavy fastening where breakaway torque matters more than weight

What reviewers say

  • 4.4 / 5157 ratings

Rated 4.4 out of 5 from 157 ratings. Owners value the torque for breaking loose rusted and stubborn fasteners, and the speed settings give useful control. The main complaints are the weight and size, and that it arrives as a bare tool.

What people mention
  • TorquePraisedOwners say it breaks loose rusted and stubborn fasteners that smaller wrenches cannot.
  • WeightCriticisedReviewers find it heavy at 6.4 lbs, especially for overhead work.
  • SizeCriticisedIts 8.8-inch length makes it awkward in tight engine bays and confined spaces.
  • Speed controlPraisedThe four speed modes and variable-speed trigger are seen as giving good control over a powerful tool.
  • Bare toolMixedBuyers note the battery and charger are sold separately, which adds to the outlay for new users.
