The NitroCat 1200-K is a no non-sense, hard hitting 1/2" impact wrench that outperforms anything in its class! Used by many NHRA Top Fuel Race teams. All the Power, Half the Noise!
The Twin Clutch design uses a hammer fixed directly onto the input shaft, with a pair of pins acting as clutches. When the hammer rotates past the anvil, a ball ramp pushes the pins outwards against a spring, extending them to where they will hit the anvil and deliver the impact, then release and spring back into the hammer, usually by having the balls "fall off" the other side of the ramp at the instant the hammer hits. Since the ramp need only have one peak around the shaft, and the engagement of the hammer with the anvil is not based on a number of teeth between them, this design allows the hammer to accelerate for a full revolution before contacting the anvil, giving it more time to accelerate and delivering a stronger impact.
The AIRCAT tool line has a substantially reduced level of noise while retaining more power and torque. This feature benefits not only the mechanic but also the overall business. The patented tuned exhaust muffler technology, in all the tools, allows discharged air to pass without developing back pressure, thus retaining more power, while significantly reducing noise. AIRCAT has innovated through-the-handle exhaust design, which incorporates its revolutionary worldwide patented internal muffler/filter. The benefits include reduced hazards from breathing exhausted air particulates, the elimination of blow-by into the operators eyes and lungs as well as reduce noise. AIRCAT also incorporates a patented ergonomically engineered handle design to relieve stress and fatigue on the operators hands, wrists and arms. The patented AIRCAT handle offers better overall distribution of weight for a balanced tool and provides a unique grip that makes it easier to use for prolonged periods of time.
