1/2″ Brushed Aluminum Impact Wrench 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. Our tools have been tested & shown to operate at 82-86 dBa ,far below the OSHA guidelines.
