Is the DeWalt ATOMIC 3/8-inch impact wrench worth it?

For car and light-truck work in tight spaces, yes. It delivers 450 ft-lb in a 6-inch body and runs on the widely available 20V MAX batteries. If you mostly loosen heavy truck lug nuts, a 1/2-inch high-torque wrench is a better fit.

Does it come with a battery and charger?

It includes one 20V MAX lithium-ion battery but no charger and no case. You need a DeWalt 20V MAX charger, or another charged pack from the same line.

How does it compare to the full-size DeWalt 1/2-inch impact wrench?

The ATOMIC is shorter and lighter, which helps in tight spots, but its 450 ft-lb is well below the high-torque 1/2-inch models. Choose this for access and portability, the larger one for stubborn fasteners.

What size sockets does it take?

It has a 3/8-inch square drive with a hog ring anvil, so it takes standard 3/8-inch impact sockets. Use impact-rated sockets, not chrome hand sockets.

How long does the battery last?

Runtime depends on the pack and the job. With the included battery, expect a few dozen lug nuts or a short session of bolt work; a larger DCB205 pack extends that considerably.

DeWalt 20V MAX tools tend to drop around major holiday sales and when bundled with batteries. Watch the price history for dips below the recent range before buying.

Our take on the DeWALT ATOMIC 20V MAX 3/8" Cordless Impact Wrench Hog Ring Anvil

The DeWalt ATOMIC 20V MAX 3/8-inch impact wrench is a compact cordless tool with a brushless motor rated at 450 ft-lb of torque, 2,500 RPM and 3,550 BPM. Its 6-inch length and pistol grip make it one of the shorter 20V MAX impact wrenches, aimed at tight engine bays and under-dash work. It uses the friction ring (hog ring) anvil for quick socket changes and ships with one 20V MAX battery but no charger or case.
