Does the DCF923B come with a battery?

No. It is a bare tool, so you need a DeWalt 20V MAX battery and charger, sold separately.

How much torque does it make?

Up to 300 ft-lbs of fastening torque and 450 ft-lbs of breakaway torque.

What socket size does it take?

It has a 3/8 in hog ring anvil, so it uses 3/8 in drive sockets.

Can it remove lug nuts?

It can handle many passenger-car lug nuts, but heavy truck or over-torqued lugs are better left to a high-torque 1/2 in impact wrench.

What is Precision Wrench mode?

A control mode that slows the tool as the fastener tightens to help prevent overtightening and run-off.

What is Timber Screw mode for?

It optimizes speed for driving wood screws in carpentry and framing.

What reviewers say

4.6 / 571 ratings

Rated 4.6 out of 5 from 71 ratings, owners treat it as a strong compact 3/8 in impact wrench. They like the power for its size and the control modes; the main gripe is that it ships without a battery.

What people mention

PowerPraisedOwners say it loosens and drives fasteners that seem too much for its size.
SizePraisedReviewers value the compact body for engine bays, under seats and overhead work.
Control modesPraisedThe four speeds and Precision Wrench are called useful for assembly and finish work.
Work lightPraisedThe adjustable LED is described as bright enough for dim, confined spaces.
BatteryCriticisedBuyers note it arrives as a bare tool, so a 20V MAX battery and charger are extra.
Torque ceilingMixedSome say it cannot match a full-size 1/2 in impact on the heaviest fasteners.

About the DEWALT ATOMIC 20V MAX 3/8 in Cordless Impact Wrench DCF923B

The DEWALT ATOMIC 20V MAX 3/8 in cordless impact wrench has a compact body for working in tight spaces, such as cabinets, under seats or overhead. It delivers up to 300 ft-lbs of fastening torque and up to 450 ft-lbs of breakaway torque for loosening or driving stubborn fasteners.

It has four speed settings. Precision Wrench control helps prevent overtightening and fastener run-off. Timber Screw mode optimizes speed when driving wood screws. A hog ring anvil allows quick, secure socket changes, and an onboard LED work light with adjustable brightness lights up dim or confined work areas.

The housing is glass-filled nylon, which resists oils and solvents on job sites. The grip is balanced and ergonomic, with weight distributed to reduce fatigue during longer sessions. This is a tool-only unit and works with 20V MAX batteries, which are not included.
