DeWalt 20V MAX XR Hammer Drill & Impact Driver Kit vs DEWALT DCK277D2 Drill & Impact Driver Kit

Buy the DCK2101QQ1WW1 if you drill concrete, brick or masonry, or want maximum power and runtime. Its DCD1007 hammer drill and DCF845 impact driver are DeWalt's top 20V XR tools, with a 3-speed hammer drill, a 3-speed driver and a 4Ah plus an 8Ah POWERPACK battery. The DCK277D2 is the lighter, simpler kit: a DCD777 drill/driver and DCF787 impact driver with two compact 2.0Ah batteries, no hammer function. Owners of the DCK277D2 praise its power, triggers and battery life but some report dead batteries or a broken driver out of the box. The DCK2101QQ1WW1 rates 4.7 from 300 ratings and is the stronger, more durable kit.

  • Choose the DeWalt DCK2101QQ1WW1 if you drill masonry, drive large fasteners, or want one kit that covers heavy jobs with a big 8Ah battery.
  • Choose the DeWalt DCK277D2 if you mostly drill wood and metal, want a compact light kit, and do not need a hammer function.
