The Chicago Pneumatic 1” CP7779 impact wrench provides 1,440 ft/lbs of maximum torque. Thanks to an optimal balance and interaction between motor and clutch mechanism, this energy-efficient impact has an average air consumption of only 7.7 cfm. The CP7779 offers the convenient, S2S single-hand forward/reverse switch for more efficient operation. In any wrench position, and even in tight places, the operator can easily switch between forward and reverse with one hand. This tool features a fiber-reinforced composite body and magnesium clutch housing, and weighs only 7.7 lbs. Combined, these features help reduce both arm stress and operator fatigue.
