Overview
DeWalt's DCD798B runs on the 20 volt battery platform, rated at 4 amps and weighing 3.2 pounds, in a tool-only listing built around that shared battery system.
The listed weight of 3.2 pounds is light for a drill, which fits a bare tool sold without battery or charger, a naming pattern DeWalt commonly uses on this line. Confirm the listing includes a battery and charger before ordering if you do not already own the platform.
- 20 volt battery power
- 4 amp rating

Who it's for
Suits anyone already invested in the 20 volt DeWalt battery platform who needs a bare drill/driver to add to their kit. Not the right pick for a first-time cordless buyer who needs a battery and charger included.
Pros and cons

- Runs on the 20 volt battery platform

Performance notes
Running on the 20 volt platform at 4 amps, the drill is built for the weight class it lists at, 3.2 pounds, which favors control during longer driving or drilling sessions over sheer torque.
