Does the DCF900B come with a battery?

No. It is a bare tool, so the 20V MAX battery and charger are sold separately. You need at least one battery and a charger to run it.

What is Precision Wrench mode?

It is a control mode that helps prevent overtightening in forward and fastener run-off in reverse. It gives more control on sensitive fasteners.

What is the difference between the hog ring and pin detent versions?

The hog ring anvil grips sockets with a spring ring for fast changes. A pin detent locks the socket with a pin for more security but slower changes.

Will my existing DeWalt 20V MAX batteries work with it?

Yes. It uses the DeWalt 20V MAX battery platform, so existing 20V MAX packs fit. Higher-capacity packs give longer runtime under heavy load.

Is it too big for engine bay work?

It is a full-size high-torque wrench, so it is bulky in tight engine bays. For confined spaces a compact or mid-torque impact wrench is easier to handle.

What reviewers say

Owners and reviewers treat the DCF900B as a serious heavy-duty impact wrench, praising its breakaway torque for rusted lug nuts and its Precision Wrench control. Common complaints are its size and weight and the extra cost of batteries and a charger.

What people mention

TorquePraisedOwners say the breakaway torque removes rusted and over-torqued fasteners that smaller impact wrenches stall on.
Size and weightCriticisedReviewers call it large and heavy, which makes overhead and confined-space work tiring.
Precision WrenchPraisedUsers like the mode that limits overtightening in forward and run-off in reverse.
Battery platformPraisedBuyers value that it runs on existing DeWalt 20V MAX batteries.
Bare toolMixedSome buyers note the battery and charger are not included and add to the total outlay.
Anvil retentionMixedThe hog ring holds sockets for quick changes but some users find it less secure than a detent pin.

About the DeWalt 20V MAX 1/2 In. High Torque Impact Wrench With Hog Ring Anvil (Tool Only) - DCF900B

The DeWalt 20V MAX XR 1/2-inch High Torque Impact Wrench has a hog ring anvil and is sold as a tool only. It delivers 1030 ft-lbs of max fastening torque and 1400 ft-lbs of max breakaway torque. That suits large pipe flanges, grooved couplings, wheel lugs and other heavy-duty impact wrench work.

A 4-mode push button switch changes speed settings and LED brightness. A variable speed trigger adds control. Precision Wrench mode helps prevent overtightening when driving forward and run-off when reversing.

BATTERYGUARD is a shock-absorbing battery-to-tool connection that reduces wear and tear on the battery. An on-tool LED work light illuminates dark workspaces. The battery and charger are sold separately.
