Does the DCF850B come with a battery and charger?

No. It is a bare tool, so you need a DeWalt 20V MAX battery and charger, sold separately. If you already own 20V MAX packs, you can use them.

How does it compare with the DeWalt DCF887?

The DCF850 is shorter and lighter, which helps in tight spots. The DCF887 is a full-size driver with more torque, so it suits heavier fastening.

It has a 1/4-inch hex chuck that takes standard impact driver bits. The chuck is keyless, so bits swap by hand.

Yes. It has three speed settings plus a precision mode for small fasteners. The selector sits on the foot of the tool.

It handles deck screws and moderate lag bolts well. For long structural lags, a full-size impact driver or wrench gives more torque.

The tool only. No battery, charger, belt hook or bit holder is included.
