Overview
The DEWALT DCF815B is a 12 volt cordless impact driver weighing 1.8 pounds, with a body measuring roughly 7 by 2.75 by 7 inches and a rated speed of 2000 RPM.
DEWALT's 12 volt Max line targets compact spaces and one handed work, and the DCF815B fits that role with a body under two pounds. At 2000 RPM it runs slower than many full size 18 or 20 volt impact drivers, trading top end speed for a smaller footprint.

Who it's for
This suits buyers who want a compact, light impact driver for trim work, furniture assembly or other jobs in tight spaces. Tradespeople who need maximum torque and speed for framing or heavy fastening should look at DEWALT's larger 18 or 20 volt impact drivers instead.
Pros and cons
- Compact 7 x 2.75 x 7 inch body
- Light 1.8 pound weight for overhead work
- DEWALT 12 volt Max compatibility
- 2000 RPM trails full size impact drivers
- Bare tool, battery and charger not confirmed
- Not suited to heavy framing fasteners
Performance notes
The 2000 RPM speed and 12 volt platform put the DCF815B in DEWALT's compact tier rather than its high output range, which favors control over raw speed on small to medium screws. Its 1.8 pound weight and 7 by 2.75 by 7 inch body make it easy to maneuver in cabinets, tight corners or overhead work where a bulkier driver would not fit.
