Does the DCF921B come with a battery and charger?

No. It is sold as a bare tool with a belt clip and owner's manual. You need a 20V MAX battery and charger, which are sold separately.

How does it compare with the DeWalt 1/2-inch high-torque impact wrench?

The DCF921B is much smaller and lighter, with 300 ft-lbs fastening and 450 ft-lbs breakaway torque. The full-size high-torque model delivers far more torque but is heavier and bulkier, so it is better for the toughest fasteners.

What is Precision Wrench control?

It is a mode that pauses torque briefly after the fastener seats and slows the final tightening, which helps prevent overtightening and fastener run-off.

What is Timber Screw Mode for?

It is a speed setting tuned for driving large timber screws in wood, slowing the tool as the screw seats.

What socket drive does it use?

It has a 1/2-inch square drive with a hog ring anvil, so it takes standard 1/2-inch impact sockets.

How much torque does it make?

Up to 300 ft-lbs of max fastening torque and 450 ft-lbs of max breakaway torque, with a no-load speed of 2,800 rpm and 3,200 impacts per minute.

What reviewers say

4.6 / 529 ratings

Owners rate it highly, with 4.6 out of 5 from 29 ratings. They value the power-to-size ratio and the speed settings for control. The main complaints are that it ships as a bare tool and that it falls short of full-size wrenches on the toughest fasteners.

What people mention

PowerPraisedOwners say it removes lug nuts and suspension bolts that compact wrenches usually cannot.
Size and weightPraisedReviewers like how small and light it is for reaching into tight engine bays.
Speed settingsPraisedThe four speeds and Precision Wrench mode are called out for control on smaller fasteners.
BatteryCriticisedBuyers note it arrives as a bare tool, so batteries and a charger add to the outlay.
Torque limitsMixedSome owners find it short of a full-size wrench on heavily rusted or over-torqued fasteners.
Socket retentionMixedThe hog ring is quick but holds sockets less firmly than a pin detent, some say.
