Ingersoll-Rand air impact wrenches are designed to loosen or tighten nuts and other mechanical fasteners in high-volume, high-torque applications, such as assembly and automotive work. These wrenches feature a bronze end-plate that reduces the risk of dropping the nuts or bolts and a Twin hammer mechanism to ensure the delivery of consistent power and balance. They are further equipped with a reverse-bias motor that allows easy removing of damaged and stubborn bolts and a titanium housing to withstand the harshest industrial environment.
