Abstract
An air tool includes a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece. Power handle and idle handles have upper and lower ends connected to the housing at angularly spaced locations. Air power is supplied to the motor by an air passage extending through the power handle to an intake at the top of the housing. The upper and lower connections of the handles to the housing have axes extending generally perpendicular to each other and vibration insulators prevent metal to metal contact with the housing. One of the vibration insulators also is used in sealing against the loss of power air before entering the motor. Between their upper and lower ends, the handles are slanted at an angle of about fifteen degrees (15.degree.) relative to the axis of the tool.
