The Vevor 1" air impact wrench is built for heavy-duty repair and maintenance work on trucks, buses, tractors, boats, and industrial equipment. It delivers up to 2400 ft-lbs of max torque and 2730 ft-lbs of loosening torque for demanding fastening and removal tasks. Its aluminum construction helps keep the tool lighter for extended use, while dual D-shaped handles improve control and comfort. A 6-stage forward and reverse power management switch allows better speed and torque adjustment for different applications.
