How does the DCF850 compare with DeWalt's larger impact drivers?

It is shorter and lighter than DeWalt's full-size 20V impact drivers, which makes it better for tight spaces. The trade-off is lower peak torque and, with the compact battery, shorter runtime on heavy fastening.

What is the PowerStack battery and does it fit other DeWalt tools?

The DCBP034 is DeWalt's compact 20V Max battery, which the brand says is smaller and lighter than the DCB203 with more power. It works with all DeWalt 20V Max tools and chargers.

What comes in the DCF850E1 kit?

The kit includes the DCF850 impact driver, one DCBP034 PowerStack battery, a charger and a kit bag.

Does it have a work light?

Yes. It has a three-LED light on the tool to illuminate dim work areas.

What bit holder does it use?

It takes standard 1/4-inch hex bits, the common size for impact driver accessories.

Is it good for cabinet installation?

Yes. The short body and three speed settings let it fit inside cabinets and drive small screws without over-torquing.
