1/2" IMP WRENCH TWIN HAMMER Part# ACA-1404

The 1404 uses the rugged and reliable Twin Hammer mechanism - better suited for all-around automotive use. The twin hammer design has the hammer able to slide and rotate on a shaft, with a spring holding it in the downwards position. Between the hammer and the driving shaft is a steel ball on a ramp, such that if the input shaft rotates ahead of the hammer with enough torque, the spring is compressed and the hammer is slid backwards. All the Power, Half the Noise! The AIRCAT tool line has a substantially reduced level of noise while retaining more power and torque.
