DeWalt 20V Max DCD777C2 Drill/Driver vs DeWalt DCD793B 20V MAX Drill Driver

The DCD793B is the stronger drill: more power (404 UWO vs 340), higher top speed (1,650 vs 1,500 RPM) and a shorter body. The DCD777C2 is the better buy for most shoppers because it is a complete kit with two batteries, a charger and a bag. Build quality is similar, both are brushless DeWalt 20V tools. Owners rate the DCD777C2 highly (4.8 from 180 ratings); the DCD793B scores 4.6 from fewer ratings.

  • Choose the DCD777C2 if you want a ready-to-use kit with two batteries, a charger and a bag, and 340 UWO is enough for home repairs and assembly.
  • Choose the DCD793B if you already own DeWalt 20V batteries and want more power and a shorter body for tight spaces.

What reviewers say

DeWalt 20V Max DCD777C2 Drill/Driver

  • 4.8 / 5180 ratings

Rated 4.8 out of 5 from 180 ratings, owners treat the DCD777C2 as a dependable general-purpose drill. They like the compact size, the brushless run time and the two-battery kit. The main complaints are the small 1.5 Ah batteries and limited torque for heavy jobs.

What people mention
  • Battery lifeMixedOwners say the brushless motor stretches each charge, but the 1.5 Ah packs drain fast in heavy drilling.
  • Size and weightPraisedThe 7.6-inch body fits into tight spaces, though some find 5.8 lbs on the heavy side.
  • PowerMixed340 UWO and 500 in-lbs handle everyday drilling and driving but struggle with large hole saws.
  • ChuckPraisedThe 1/2-inch keyless ratcheting chuck grips bits firmly and is easy to change.

DeWalt DCD793B 20V MAX Drill Driver

  • 4.6 / 528 ratings

Rated 4.6 out of 5 from 28 ratings. Owners like the compact size, the power for its class and the light weight, and most complaints center on it arriving without a battery, which is expected for a bare tool.

What people mention
  • SizePraisedOwners say the short head gets into spaces a full-size drill will not fit.
  • PowerPraisedReviewers find the brushless motor strong enough for decking and framing tasks.
  • WeightPraisedAt 2.38 lbs bare, it is easy to use overhead for long stretches.
  • ChuckPraised

Questions and answers

Which is better for driving screws?
The DCD793B has more power and 15 clutch positions, so it drives screws more precisely. The DCD777C2 handles everyday driving fine with its 2-speed transmission.
Which lasts longer on a charge?
The DCD777C2 ships with two 1.5 Ah batteries, so you can swap and keep working. The DCD793B has no battery, so runtime depends on the packs you already own.
Is the DCD793B worth stepping up to?
Yes if you already own DeWalt 20V batteries and want more power in a shorter body. If you are starting from nothing, the DCD777C2 kit gets you working with no extra purchases.
Which is better for tight spaces?
The DCD793B is shorter front to back at 6.38 in. and lighter, so it fits between studs and into cabinets more easily.
Do both use the same batteries?
Yes, both run on DeWalt 20V MAX batteries. The DCD777C2 includes two; the DCD793B does not include any.
