DeWalt DCK227D2 20V Combo Kit vs DeWalt XTREME 12V MAX Drill & Impact Kit

Buy the 20V MAX DCK227D2 if you drill into framing, masonry anchors, or anything bigger than a half-inch spade bit; its 404 UWO drill and 1,700 in-lb impact driver do real construction work. Buy the 12V MAX XTREME DCK221F2 if you work in cabinets, panels, and tight electrical boxes; both tools are shorter and lighter, and the Precision Drive mode protects small fasteners. The 20V kit has the stronger platform and a 1/2-inch chuck, the 12V kit has the better control and reach. Owners rate both well, though the 12V kit has far more ratings behind it.

• Choose the 20V MAX DCK227D2 if you need one kit for framing, decking, and heavy fastening and want batteries that fit the whole DeWalt 20V line.
• Choose the 12V MAX XTREME DCK221F2 if you install cabinets, fixtures, or electrical work and want the shortest, lightest tools with fine clutch control.
