The AIRCAT VIBROTHERM Series of Impact Wrenches are not your ordinary Impact Wrenches. For decades pneumatic impact wrench mechanisms, motor designs and styling have followed traditional design concepts that date back to the early 1970s. Over the past year through innovation in engineering, technology and investments in new manufacturing processes, AIRCAT has developed a truly new impact wrench hammer mechanism and motor drive. We also have incorporated a triple injection, 3 color housing/handle molding process which delivers a new state of the art" appearance. Carrying the trusted AIRCAT brand, the VIBROTHERM DRIVE impact wrench series is protected with 4 US/Global patents as well as the new VIBROTHERM DRIVE registered trade mark. AIRCATs VIBROTHERM DRIVE series of tools deliver high torque, low vibration, low noise, low weight, shorter length, longer working life and unmatched styling designs and operating comfort/convenience. AIRCAT backs-up VIBROTHERM DRIVE with an unprecedented 3-year warranty.
