DEWALT 20V MAX XR DCF891B Impact Wrench Review (2027)
In-depth review of the DEWALT DCF891B: 800 ft-lb breakaway torque, Precision Wrench control, and four speeds in an under-4 lb body.
DEWALT 20V MAX XR DCF891B 1/2 in Mid-Torque Impact Wrench
Compact DEWALT mid-torque wrench with Precision Wrench control.
Our verdict
The DCF891B posts the strongest breakaway number in the mid-torque class, 800 ft-lb, and backs it with Precision Wrench control that keeps that power from snapping or scattering fasteners. DEWALT users who change tires and run shop hardware get high-torque appetite in a compact, under-4 lb tool.
What we like
- 800 ft-lb breakaway torque tops the mid-torque class here
- Precision Wrench control manages output before fastener loss or overtightening
- Four speed settings plus a variable speed trigger
- Under 4 lb tool-only weight with an LED work light
What to watch out for
- Bare tool only, no battery or charger in the box
- Hog ring anvil only in this variant
- Breakaway peaks do not equal sustained high-torque output
What owners report: DEWALT 20V MAX XR DCF891B 1/2 in Mid-Torque Impact Wrench
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Class leading mid torque breakaway frees lug nuts that defeat smaller wrenches
- Precision Wrench control slows output before fasteners run off or overtighten
- At under four pounds bare, it is easy to handle around wheel wells
Common complaints
- It arrives as a bare tool, so battery and charger are a second purchase
- The hog ring anvil is the only retention style in this variant
- Breakaway peaks do not equal the sustained output of a high torque wrench
Who it is for
DEWALT 20V MAX owners doing tire, suspension, and general shop work.
Breakaway strength
With 600 ft-lb of fastening torque and 800 ft-lb of breakaway, the DCF891B frees rusted lugs and hardware that mid-torque rivals rate below. Sustained heavy work still belongs to the DCF900 class, but the gap shows up less often than the spec sheets suggest.
Precision Wrench control
Precision Wrench manages output in forward and reverse to prevent overtightening and fastener run-off, and four speed settings plus a variable speed trigger cover everything from small hardware to lug nuts. An LED work light and belt clip round out the shop-ready details.
Size and platform
Under 4 lb tool-only with a brushless motor, it carries all day on a belt and runs on the 20V MAX batteries DEWALT users already own. The hog ring anvil swaps sockets fast, which matters when one job mixes sizes.

Questions, answered
How is this different from the DCF900?
The DCF891B is the mid-torque model: smaller and lighter, with 800 ft-lb breakaway against the DCF900 high-torque class. Daily tire and shop work fits the 891; seized heavy hardware fits the 900.
Does it come with a battery?
No, the DCF891B is a bare tool. Any DEWALT 20V MAX battery runs it, and a 5.0Ah pack balances runtime and weight for shop use.
