Overview
The DEWALT DCF801B is a 12 volt cordless impact driver spinning up to 2,850 RPM and weighing 1.75 pounds. The B suffix marks this as a bare tool listing, sold without a battery or charger.
This is DEWALT's compact 12 volt line, built for tight spaces where a full size 20 volt impact would not fit. At under two pounds and just over 9 inches long, it is sized for overhead work and cramped cabinetry rather than heavy framing jobs.

Who it's for
Fits someone who already owns DEWALT's 12 volt battery system and wants a light, compact impact driver for finish work or tight-access jobs. Less suited to anyone needing maximum torque for large lag bolts, where the larger 20 volt line is the better fit.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact 9 inch length for tight spaces
- Light at 1.75 pounds
- 2,850 RPM for fast driving on small fasteners
- Bare tool, no battery or charger included
- 12 volt platform has less torque than 20V tools
- Not suited to heavy fastening work
Performance notes
At 2,850 RPM the DCF801B spins faster than most full size impact drivers, which suits smaller fasteners and finish hardware rather than driving large lag screws. Its 9 inch length and 1.75 pound weight are built for reaching into cabinets and overhead spots where a bigger tool cannot fit.
