A compact impact driver sold as a bare tool, so a compatible DEWALT battery and charger are needed. The listing gives two different speed figures and no torque rating.

Overview
DeWalt built the DCF815B as a compact impact driver in a plastic housing, drawing power from DEWALT batteries in its compact line. It arrives without a pack, and the chuck size is stated but the torque is not.
Small size and a light body make it easy to use overhead or in tight spaces, and a bare tool suits anyone who already owns packs. The limitation is the missing torque figure and two speed numbers that are not explained.
Who it's for
Tight spaces, overhead work and repeated screw driving where a smaller body helps are the typical jobs. People who need to drive large lag screws or who have no compatible batteries should look at a full kit or a bigger driver.
Pros and cons
- Compact, light body
- Bare tool for existing battery owners
- Lithium ion battery type
- Torque not listed
- Two different speed figures given
- Battery and charger not included
- Run time not stated
Performance notes
An impact driver delivers short rotational blows when the screw resists, so speed and the battery's output both shape how quickly it sets fasteners. Because the listing shows both a maximum rotational speed and a separate speed, expect the working figure to depend on load. Pack charge level matters as well.
