DeWalt DCD793D1 20V Drill/Driver Kit vs DeWalt ATOMIC 20V Cordless Drill/Driver Kit

These are close cousins: both are 20V MAX brushless DeWalt drill/drivers with 1/2 in. keyless chucks, 404 UWO, 1,650 RPM top speed, two speeds and an LED light. The DCD793D1 is the newer, shorter body (6.38 in. head vs 5.88 in. on the Atomic) and ships with a 2.0Ah battery, charger and belt hook. The Atomic kit bundles a 5Ah battery plus a 2Ah battery, so it runs longer between charges and gives you a spare. Pick the Atomic kit for runtime and two batteries; pick the DCD793D1 for the latest compact chassis and lighter bare tool.

  • Choose the DeWalt DCD793D1 if you want the newest compact brushless chassis and a lighter tool for overhead and cabinet work.
  • Choose the DeWalt Atomic kit if you want a 5Ah battery plus a spare 2Ah in the box for long runtime and back-to-back jobs.

What reviewers say

DeWalt ATOMIC 20V Cordless Drill/Driver Kit

Owners of the ATOMIC line generally like the short body and the power for its size, and the two-battery kit gets praise for value when it's discounted. The common complaints are heat and slowdown under hard, continuous use and a price that runs high at list.

What people mention
  • SizePraisedOwners say the short body gets into cabinets and between studs where full-size drills won't fit.
  • PowerMixedIt handles screws and holes well for its size, but bogs down in big bits and hard material.
  • HeatCriticisedContinuous heavy use makes the motor hot and triggers slowdown.
  • BatteryPraisedThe 5Ah and 2Ah pair is seen as a strong kit, with the small pack keeping the drill light.

Questions and answers

Which has longer runtime?
The Atomic kit, because it includes a 5Ah battery. The DCD793D1 ships with a single 2.0Ah pack, so it needs charging sooner under heavy use.
Which is more compact?
The Atomic, at 5.88 in. head length versus 6.38 in. on the DCD793D1. Both are short enough for cabinet and overhead work.
Do they have the same power?
Yes. Both list 404 UWO and 1,650 RPM no-load top speed with a brushless motor, so drilling and driving performance is effectively the same.
Is the Atomic kit worth stepping up to?
If you work long sessions or rotate batteries, yes. The extra 5Ah pack and spare 2Ah make it the better all-day kit. If you want the newest, lightest body, the DCD793D1 is the pick.
Do batteries and chargers interchange?
Yes. Both are DeWalt 20V MAX tools, so the batteries and charger work across the 20V MAX line.
Which is better for tight spaces?
The Atomic's shorter head gives it a slight edge in tight spots, though the DCD793D1 is lighter overhead.
