Head-to-head
DeWalt DCF887 vs DCF850 — which compact impact driver?
DCF887 is the XR 3-speed classic. DCF850 is the ATOMIC compact with a shorter head. Here's which one goes in your bag for overhead and tight-spot work.
DeWalt DCF887 (20V MAX XR)
The XR workhorse. 3 speeds, precision drive, 1,825 in-lb. Head length 5.3". The impact driver most contractors already own.
DeWalt DCF850 (ATOMIC)
ATOMIC compact brushless. 3 speeds, 1,825 in-lb. Head length 4.25" — over an inch shorter than DCF887. Built for cabinets, ceiling grid, and overhead.

DCF850 for most new buyers. DCF887 if you need the XR pedigree.
Same 1,825 in-lb torque, one inch shorter head, quarter-pound lighter, ~$10 cheaper. For 90% of jobs the DCF850 is the smarter buy in 2026. The only time to pick DCF887 is if your crew already standardizes on XR kits or if you specifically need the longer-head balance for deck-screwing in open framing.
FAQ
Is the ATOMIC line as durable as XR?+
In our field-use observations, yes. ATOMIC is DeWalt's "compact pro" tier, not a homeowner line. Same brushless motor architecture, same warranty, same bearings. The tradeoff is ergonomic, not durability.
Do both tools use the same batteries?+
Yes — any DeWalt 20V MAX, 20V MAX XR, or FlexVolt pack (which steps down to 20V automatically).
