Which is better for driving long deck screws?

The 20V kit. Its DCF885 impact driver delivers impact force the 12V drill/driver does not have, and the 1.3 Ah packs still outlast the single 12V battery on sustained work.

Which is better for cabinet and furniture work?

The XTREME 12V. At under 5 in. long and 1.6 lbs, it fits where the 20V drill will not, and the 15-position clutch gives fine control on small screws.

Is the 20V kit worth $4 more?

Yes for most shoppers. At $129.00 at Amazon versus $124.99 at eBay as of November 4, 2026, you get a second tool, a second battery and a 1/2 in. chuck for about the price of a coffee.

The XTREME 12V has a brushless motor, which typically outlasts the brushed motors in the 20V kit. The 20V kit's advantage is two batteries and two tools, not motor life.

Can the 12V drill handle drilling into masonry?

No. Neither kit is a hammer drill. For masonry you need a hammer drill, which neither of these is.

Do both use the same batteries?

No. The 20V kit uses DeWalt 20V MAX packs and the XTREME uses 12V MAX packs. They are not interchangeable.
