Our take on the DeWALT DCF850B ATOMIC 20V MAX 1/4" Li-Ion 3-Speed Impact Driver - Bare Tool

The DeWalt DCF850B is a bare-tool 20V MAX impact driver built around a brushless motor rated at 1,825 in-lb of torque and 3,250 rpm. Its head is under 4 inches long, so it fits into tight spots where full-size drivers won't go, and a three-speed variable trigger lets you dial power down for small fasteners. It ships without a battery or charger, so it only makes sense if you already own DeWalt 20V MAX packs. Against compact rivals it trades a little top-end speed for size and control, and owners generally rate its power-to-size ratio highly.

What reviewers say

Owners and reviewers consistently praise the DCF850 for its power in a very short body and for the control the three-speed trigger gives. Most criticism centers on it being a bare tool and on the light and grip rather than performance.

What people mention
  • SizePraisedOwners say the sub-4-inch head gets into places larger impact drivers cannot.
  • PowerPraisedReviewers report it drives large screws and lag bolts without bogging down.
  • Speed controlPraisedThe three-speed trigger is called out for precise work on small fasteners.
  • Bare toolCriticisedBuyers note it arrives without a battery or charger, so the total cost depends on what you already own.
  • Work lightMixedThe 3-LED light helps in dark spaces, though some find it less even than a ring light.
  • GripMixedA few owners say the compact handle feels less planted during heavy driving.

Questions and answers

Does the DCF850B come with a battery?
No. It is a bare tool: the box holds the impact driver, a belt hook and the owner's manual. You need a DeWalt 20V MAX battery and charger.
How does it compare with the DCF845?
The DCF850 is shorter and lighter, which helps in tight spots. The DCF845 is a larger, more conventional driver with a longer body and a different feel in the hand.
What bit does it take?
It has a 1/4-inch hex quick-release chuck, so it accepts standard 1/4-inch hex driver bits and bit holders.
Is the three-speed trigger useful?
Yes. The low settings let you drive small screws without stripping heads, and the top setting delivers full torque for large fasteners.
What is the warranty?
DeWalt covers it with a 3-year limited factory warranty, plus a 30-day satisfaction guarantee.
Can it drive lag bolts?
With a charged 20V MAX pack it handles many lag bolts and large-diameter screws, though very long lags in hard wood may call for a higher-torque driver.
