DEWALT DCK2050M2 Hammer Drill Combo Kit vs DeWalt DCK211S2 12V MAX Drill/Impact Combo Kit

Buy the 20V MAX XR kit (A) for heavy work: it has a hammer-drill mode for masonry, a 1/2-inch metal ratcheting chuck, brushless motors and two 4.0Ah batteries. The 12V MAX kit (B) is smaller and lighter, with a 3/8-inch chuck and a 40-minute charger, so it suits cabinet installs, electrical work and overhead jobs. Owners rate A 4.5 from 291 ratings and B 5 from 23; A has far more feedback, and some A buyers report missing batteries or parts, so check the box on arrival.

• Choose the 20V MAX XR kit if you drill concrete or brick, drive large screws all day, or want brushless motors and bigger batteries.
• Choose the 12V MAX kit if you want a light kit for cabinet, electrical and finish work where a compact tool matters more than raw power.
