Is the Untimaty impact wrench worth it at $38.98?

At $38.98 at Walmart as of November 4, 2026, it is one of the cheapest brushless 1/2-inch impacts you can buy. It suits occasional home use, but a 3.4 rating from 194 buyers means you should not expect pro-grade reliability.

Will 320 ft-lbs remove stuck lug nuts?

Yes for most passenger cars, whose lug nuts are typically torqued to 80-150 ft-lbs. Rusted or over-torqued truck nuts may need a breaker bar first.

How long does the battery last and how long to charge?

The kit includes one 21V 3.0 Ah battery that takes 2-3 hours to charge. Expect a few dozen lug nuts per charge, less under continuous heavy load.

What comes in the box?

The wrench, one 21V 3.0 Ah lithium-ion battery, a charger, and seven sockets. A case is not listed.

Does it use standard 1/2-inch sockets?

Yes. The 1/2-inch square drive takes standard impact-rated sockets, and seven are included to start.

When is the best time to buy it?

Only one store lists it new, at $38.98 as of November 4, 2026, so there is no price history to time. Watch for holiday tool sales at Walmart.

Our take on the Untimaty 1/2 inch Brushless Cordless Impact Wrench

The Untimaty is a cordless 1/2-inch impact wrench built around a brushless motor rated at 320 ft-lbs (430 N.m) of torque, with a 21V 3.0 Ah lithium-ion battery and charger in the box. It spins up to 3,000 RPM, weighs 3.53 lb, and ships with seven sockets and an LED work light. At $38.98 at Walmart as of November 4, 2026, it is the only new price listed, so there is no recent range to compare against. That is very cheap for a brushless 1/2-inch impact, which is the main reason to consider it and the main reason to be careful.
