The drill-driver is the most versatile tool in any kit, and DeWalt makes several on the 20V MAX platform. The DCD791 is the mid-range sweet spot. The DCD800 is the ATOMIC compact flagship. Every model includes an adjustable clutch for driving screws without stripping, which separates drill-drivers from impact drivers.
DeWalt 20V MAX Platform
All DeWalt 20V MAX batteries work. For drill-driver work, a 2.0Ah compact pack is the best balance of weight and runtime. Save the heavy 5.0Ah packs for tools that need them.

Frequently Asked Questions
What's the difference between a drill-driver and an impact driver?
A drill-driver has an adjustable clutch that lets you set the torque limit for driving screws. An impact driver has more torque and uses hex-shank bits. For screws in wood, the clutch on a drill-driver prevents overdriving and stripping. For lag bolts and long fasteners, the impact driver's torque is better.
DCD791 or DCD800?
The DCD800 is shorter, lighter, and has more torque. It costs $10 more. For most buyers, the DCD800 is the better pick. The DCD791 is still a solid tool, and it shows up in bundle deals more often.
Do I need both a drill-driver and an impact driver?
Owning both is the standard recommendation because they complement each other. The drill-driver handles precision work (screw driving, small holes with controlled depth). The impact driver handles brute-force fastening. If you can only buy one, start with a drill-driver.
