Which is better for removing lug nuts?

The DCF961B. Its 1/2 in drive fits standard lug sockets, and its 1,750–1,900 ft-lbs breakaway is plenty for most passenger and truck lugs. The DCF964B has more torque but needs 3/4 in sockets or an adapter.

Is the DCF964B worth the extra $104?

Only if you need a 3/4 in drive. It adds about 220 ft-lbs of fastening torque and the auto-boost feature, but it weighs 9 lbs and ships without a battery. For auto work, the DCF961B covers it for less.

Which has more torque?

The DCF964B, at 1,420 ft-lbs fastening and 1,900 ft-lbs breakaway. The DCF961B is rated 1,030–1,200 ft-lbs fastening and 1,750–1,900 ft-lbs breakaway, depending on which figure you read.

Do both use the same 20V MAX batteries?

Yes. Both run on DeWalt 20V MAX packs, so one battery set works across both tools. The DCF961B listing includes a 5Ah battery; the DCF964B is tool only.

Which is easier to handle all day?

The DCF961B. At 6.4 lbs and 8.8 in long it is 2.6 lbs lighter and 1.2 in shorter than the DCF964B, which matters overhead and under vehicles.

Both use brushless motors and hog ring anvils, so life depends on use. The DCF964B is built for industrial duty and heavier loads, but running the DCF961B within its torque range on auto work is easier on the tool.
