About Product Overview

DeWalt's ATOMIC line is built around one idea: shrink the tool without shrinking the power. This DCF850B 3-speed impact driver backs that up with 1825 in-lbs of torque and 3800 impacts per minute, all packed into a body that's just 3.97 inches long from tip to tail. That short length matters most in framing bays, cabinet interiors, and tight engine compartments where a full-size driver simply won't fit.

The brushless motor means less wasted energy and a longer service life, while the 3-speed selector lets you dial back power for delicate fastening or open it up for deck screws and lag bolts. A built-in LED lights up dark corners and behind-panel work. This is sold as a bare tool, so it drops right into an existing 20V MAX battery lineup - a practical choice for anyone already running DeWalt cordless gear who needs a compact driver for the jobs their full-size model can't reach.

  • Torque: 1825 in-lbs, up to 3800 impacts per minute
  • 1/4-inch hex drive, brushless motor
  • 3-speed variable trigger for control across materials
  • Compact 3.97-inch length for tight-access work
  • Built-in LED work light
  • Tool only - no battery, charger, or case included

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
