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.
