Overview
The DEWALT DCF787C1 is a 20-volt cordless impact driver rated at 1.3 amps and 2,800 RPM, weighing 4.4 pounds.
The C1 in the model number is DEWALT's usual marker for a kit that ships with a single battery and charger rather than a bare tool. Zero recent purchases alongside a high historic rating is worth noting: it may reflect a listing that has gone out of stock or been superseded rather than a quality problem, since the review count and score are both strong.

Who it's for
Fits users who want a 20V cordless impact driver at 2,800 RPM for everyday fastening work and already run DEWALT's 20V battery platform. Less relevant for anyone needing a hammer drill or a higher-torque impact wrench, since the listed specs describe a standard impact driver.
Pros and cons
- Runs on the 20V DEWALT battery platform
- 2,800 RPM for everyday fastening tasks
- Light at 4.4 pounds for extended use
- No torque figure listed
- No description confirms kit contents
Performance notes
At 2,800 RPM and 1.3 amps, this reads as a standard-duty impact driver built for driving screws and small fasteners rather than heavy bolt work. The 4.4 pound weight keeps it maneuverable in tight spaces, and running on the 20V platform means battery and charger typically interchange with other DEWALT 20V tools.
