ABSTRACT:
Generally, a pneumatic rotary tool of the present invention comprises a housing formed of a plastic material and includes a motor receptacle having a front end and an open rear end. An air motor is disposed within the motor receptacle of the housing. An air inlet passage extends to the motor for delivering pressurized air to the motor to power the motor to drive an output shaft. An end plate of the motor has air passaging formed therein, at least part of the air passaging defining a portion of the air inlet passage. A torque selector is at least partially received in the end plate and includes a portion disposed in the air passaging defined in the end plate and at least partially blocking the flow of air in the air passaging except through the portion of the torque selector.
