DeWalt DCD801B 20V MAX XR Drill/Driver vs DEWALT DCD794D1 Atomic 20V Drill Driver

The DCD801B is the stronger drill: more torque headroom, a metal ratcheting chuck, the anti-rotation kickback shutdown and a three-position light. The DCD794D1 is the smaller, lighter kit that comes with a battery and charger, so it works out of the box. Buy the DCD801B if you already own 20V MAX batteries and want a tool that holds up to heavy drilling and driving. Buy the DCD794D1 if you want one compact drill with everything needed to start, and mostly work in wood and light metal.

  • Choose the DCD801B if you already have 20V MAX batteries and want a metal chuck, anti-rotation kickback control and more power for heavy drilling and driving.
  • Choose the DCD794D1 if you want a lighter, compact drill that arrives with a battery and charger and handles home and light trade work.

What reviewers say

DEWALT DCD794D1 Atomic 20V Drill Driver

  • 4.6 / 565 ratings

Rated 4.6 out of 5 from 65 ratings, buyers like the small size and light weight for assembly and tight-space work. The main complaints are the single small battery and the lack of hammer function.

What people mention
  • SizePraisedOwners say the short head and slim body get into cabinets and between studs where larger drills will not fit.
  • WeightPraisedAt about 2.4 lbs bare, buyers find it easy to hold overhead and for long assembly sessions.
  • PowerPraisedThe brushless motor and 404 UWO are described as strong for a compact drill.
  • BatteryCriticisedReviewers say the single 2.0Ah pack runs down quickly in sustained drilling and a second battery would help.

Questions and answers

Which is better for driving long screws and deck work?
The DCD801B. It has more power, a higher top speed and a metal ratcheting chuck that grips bits under load. The anti-rotation shutdown also helps when a bit binds.
Which is better for cabinet work and tight spaces?
The DCD794D1. It is shorter and lighter at 2.4 lbs, which makes overhead and close-quarter work easier. Its lower top speed is fine for small bits and pilot holes.
Do I need to buy batteries for the DCD801B?
Yes, unless you already own 20V MAX packs. The DCD801B is sold as a bare tool. The DCD794D1 kit includes one 2.0Ah battery and a charger.
Which one lasts longer?
Both use brushless motors and share the 20V MAX platform. The DCD801B's metal ratcheting chuck and anti-rotation system are built for harder use, so it should hold up better to heavy drilling and driving.
Is the DCD801B worth stepping up to from the DCD794D1?
If you drill masonry, drive large fasteners or work overhead on ladders, yes. The extra power, metal chuck and kickback control matter there. For light home jobs, the DCD794D1 is enough.
Can I use the same batteries in both?
Yes. Both run on DeWalt 20V MAX lithium-ion packs, so one set of batteries covers either drill.
