Overview

DeWalt sells the DCD799B as a bare 20V Max drill/driver, meaning the battery and charger are not part of this listing. It draws 4 amps, tops out at 1650 RPM, and weighs 2.53 pounds.

DeWalt commonly uses a B at the end of a model number to flag a bare tool listing, and that lines up with what is published here: no battery spec is included alongside the 20V Max power source. That keeps the price low for anyone already stocked with DeWalt 20V Max packs, but a first time buyer needs to budget for a battery and charger separately. Torque and clutch settings are not listed.

Who it's for

Fits DeWalt 20V Max owners adding a spare or backup driver to their kit. Poor fit for someone with no compatible batteries who wants a ready to use tool out of the box.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Compact, 2.53 pound body for one handed use
Fits the wide DeWalt 20V Max battery lineup
1650 RPM for fast driving

What to check first

Sold bare, no battery or charger included
No published torque or clutch data

Performance notes

1650 RPM and a 4 amp draw put this in driving and light drilling territory rather than heavy boring work. The 7 by 2 by 8 inch, 2.53 pound body stays maneuverable in framing, cabinet, or overhead work where a bulkier drill would be awkward.
