The DCD794B is the Atomic series drill, DeWalt's shortest and lightest brushless 20V MAX class. Its compact body fits where a standard drill will not, while the brushless motor keeps run time long for its size. A 1/2 inch chuck is retained, so bit range stays wide.
Compared with the DCD777D1 it is a more modern and more compact design, and it has the same battery platform. It is not as strong as the Milwaukee M18 2606-21CT, which publishes 500 in-lbs, but it is easier to hold overhead. For cabinet work, door hardware and small repairs it is excellent.
It is sold as a bare tool, so budget separately for batteries if you do not own them. Smaller packs make it very light, while larger packs add run time and weight. Spare batteries are the cheapest upgrade you can make to any of these.
