DeWalt 20V MAX Cordless Drill/Driver Kit vs DeWalt 20V Max Drill and Impact Driver Kit

Buy the DCD791 drill/driver kit if you want one compact, well-sorted drill with two 2.0Ah batteries and a hard case. Buy the combo set if you also need an impact driver for driving screws and lag bolts, and can live with smaller 1.3Ah batteries and a soft bag. The drill kit has the better-documented build and the higher rating; the combo set adds a second tool but owners report shorter runtime and some failures on the driver's bit retainer.

• Choose the Dewalt drill/driver kit if your work is mostly drilling and light driving and you want the compact body, metal ratcheting chuck and two larger batteries.
• Choose the Dewalt drill and impact driver set if you want both tools in one purchase and need the impact driver's 1,700 in-lb of torque for screws and fasteners.
