Is this kit good for drilling into brick and concrete?

The hammer drill handles small holes in brick and block. For repeated or large-diameter holes in hard concrete, a corded SDS rotary hammer is the better tool.

How does it compare with DeWalt's larger 20V combo kits?

This Atomic pair is smaller and lighter but less powerful than DeWalt's full-size hammer drill and impact driver kits. Choose it for portability; choose the larger kits for heavy daily use.

What comes in the box?

The hammer drill/driver, the impact driver, two 20V MAX lithium-ion batteries, a charger and a carrying bag.

Do both tools use the same battery?

Yes. Both run on DeWalt's 20V MAX lithium-ion batteries, and the included packs fit either tool.

Does the impact driver have a bit holder or belt hook?

It has a 1/4-inch hex quick-insert chuck for bits and a removable belt hook.

Is the chuck keyless?

The hammer drill has a quick-release keyless chuck for swapping bits by hand.
