Is the DCD778D2 worth it over a plain drill/driver?

Yes if you drill into brick, block or concrete even occasionally. The hammer mode costs little extra and saves buying a separate rotary hammer for light masonry. For wood and metal only, a standard drill/driver is lighter and cheaper.

How does it compare with the DCD777?

The DCD777 is the same drill without hammer mode. The DCD778D2 adds the hammer function and the same 20V MAX brushless platform, so it is the better pick if masonry is on your list.

How long does the 3.0 Ah battery last?

Expect roughly 200 to 300 small holes or a few dozen 1-inch holes in wood per charge, depending on load. Masonry drilling drains it faster. A second battery or a 5.0 Ah pack is a sensible add-on.

What comes in the box?

The drill, one 20V MAX 3.0 Ah lithium-ion battery, a charger and a belt hook. It does not include a hard case or a second battery.

Can it drill 1-inch holes?

Yes in wood, where the rated capacity is 1 inch. In concrete, keep bits smaller, around 1/2 inch or less, since 450 in-lbs of torque limits larger masonry bits.

Our take on the DeWalt 20V MAX Cordless Hammer Drill/Driver Kit (DCD778D2)

The DeWalt DCD778D2 is a 20V MAX cordless hammer drill/driver with a brushless motor, a 1/2-inch ratcheting chuck and a two-speed gearbox. It delivers 450 in-lbs of torque and up to 1,750 RPM, with a hammer mode for drilling into masonry. The kit includes one 3.0 Ah battery and a charger that fills it in about 60 minutes. At 2.5 lbs, it is light enough for overhead work and small enough for tight spaces.
