Our take on the DEWALT XR Slagnøgle Kulfri 4 Hastigheder 20V MAX DCF900B

The DeWalt DCF900B is a 20V MAX XR 1/2-inch cordless impact wrench built for heavy fastening: up to 1,396 Nm of fastening torque and 1,898 Nm of breakaway torque. A brushless motor, a four-speed selector and the Precision Wrench control that limits over-tightening and runaway removal set it apart from older single-speed wrenches. It suits mechanics, pipefitters and concrete crews turning large flange bolts, lug nuts and anchors. Owners rate it highly for power and control; the main complaints are its weight and bulk in tight spots.

Questions and answers

Is the DCF900B worth it over a mid-torque impact wrench?
If you regularly deal with seized lug nuts, flange bolts or anchors, the higher breakaway torque justifies it. For lighter assembly work a smaller mid-torque wrench is easier to handle.
Does it come with a battery and charger?
No. The B suffix marks a bare tool, so you need a DeWalt 20V MAX battery and charger separately.
What is Precision Wrench?
It is a control mode that slows the wrench as it tightens to reduce over-tightening, and manages run-down when removing fasteners.
What size sockets does it take?
It has a 1/2-inch square drive, so it uses standard 1/2-inch impact sockets.
Can it remove truck lug nuts?
Yes. Its breakaway torque is aimed at heavy fasteners like lug nuts, though results depend on battery capacity and condition.
