Is this impact wrench strong enough for lug nuts?

A 1/2-inch impact wrench in this class typically loosens most passenger-car lug nuts, which are usually torqued to around 80–100 ft-lb. For rusted or heavy-truck fasteners, a higher-torque pro tool is safer.

Does it come with sockets?

The listing covers the wrench and two 4.0Ah batteries. Impact sockets are usually sold separately, so check the box contents before you count on it for a tire change.

What voltage and battery does it use?

It runs on a 21V rechargeable battery and ships with two 4.0Ah packs. The batteries fit Lowe's own cordless line, not other brands' chargers.

Brushless or brushed motor?

It is brushless. That means fewer wearing parts, better runtime per charge and less heat than a brushed motor of the same class.

Can it be used for heavy daily shop work?

It suits home and light commercial jobs. For all-day shop use, pro-grade 1/2-inch wrenches from Milwaukee, DeWalt or Makita are built for that duty cycle.
