(Also known as 1/2-inch Drive Air Impact Wrench)
1/2-inch drive impact wrenches step up torque output from the 3/8-inch range for heavier automotive and industrial fastening, including lug nuts, suspension work, and structural bolting where more force is needed.

Models in this range include standard, extended-reach, and low-noise variants, each built around the 1/2-inch square drive with durable internals rated for sustained heavy-duty impact use.

1/2-inch drive impact wrenches are ideal for automotive technicians and industrial maintenance crews whose fasteners need more torque than a 3/8-inch wrench can reliably deliver.
