DEWALT DCD794D1 Atomic 20V Drill Driver vs DeWalt DCD800 XR Compact Drill Driver

Buy the DCD800 if you want the stronger, faster drill and already own DeWalt 20V batteries. It spins to 2,000 RPM and delivers 90 Nm of hard torque, against 1,650 RPM and 404 UWO on the DCD794. The DCD794 is the better first purchase: it ships as a kit with a 2.0Ah battery and charger, and it is lighter and shorter for overhead work. Owners rate both well, and the brushless motors on each hold up to steady jobsite use.

  • Choose the DCD794 if you want a ready-to-run kit with a battery and charger, and a compact, light drill for cabinet work, assembly and around-the-house jobs.
  • Choose the DCD800 if you already own DeWalt 20V batteries and want more speed and torque for driving long screws and boring larger holes.

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.

DeWalt DCD800 XR Compact Drill Driver

  • 4.7 / 535 ratings

Rated 4.7 out of 5 from 35 ratings, buyers are broadly positive about the compact size and brushless power. Complaints center on it arriving without a battery, which some buyers did not expect.

  • Size and weightPraisedOwners like how compact and light it feels, especially for overhead work.
  • PowerPraisedThe brushless motor is described as strong and smooth for its class.
  • Battery platformPraisedBuyers value that it runs on batteries they already own.
  • Bare toolCriticised

Questions and answers

Which is better for driving long screws and deck work?
The DCD800. Its 90 Nm hard torque and 2,000 RPM top speed push long screws and auger bits faster than the DCD794's 404 UWO and 1,650 RPM.
Which is better for furniture assembly and overhead work?
The DCD794. It weighs 2.4 lbs with its battery and has a 5.88 in head, so it fits between studs and reaches overhead with less fatigue.
Do I need to buy batteries for the DCD800?
Yes. The DCD800 is sold as a bare tool. It runs on DeWalt 18V XR or FlexVolt batteries, so it only makes sense if you already own some.
Which lasts longer?
Both use brushless motors and should hold up to years of regular use. The DCD800's higher torque means it works less hard on demanding tasks, but its bare-tool format gives you no spare battery to rotate.
Is the DCD800 worth stepping up to?
If you already own DeWalt batteries and drill hard materials or drive long fasteners, yes. If you are starting from nothing, the DCD794 kit gets you working with one purchase.
