APACH’s latest 1-inch pneumatic impact wrench, made from lightweight aluminum, is lighter than any other 1” impact guns on the market, reducing the user’s workload significantly. It offers three heavy-duty clutch types: twin hammer, pinless, and pin clutch, all delivering stable, high torque with exceptional durability. This wrench is powerful enough to remove lug nuts and change tires for semi-trucks, boats, bridges, and agricultural machinery. Depending on the clutch mechanism, it provides a basic torque of 2,500 to 2,700 ft-lb, with a breakaway torque reaching up to 2,800 ft-lb, surpassing other brands. The tool has also been tested for low vibration and air consumption in two reliable laboratories.
