ABSTRACT:
The invention is a pneumatic impact hammer in which the vibrations created in the motor portion of the tool are substantially reduced prior to reaching the tool's handle portion. The motor portion is allowed to move relative to the tool's handle portion and is located within a handle-attached cylindrical housing. Low-friction plastic bearings are located between the motor portion and the surrounding housing. The cycling valve that controls the reciprocating movement of the tool's piston is attached to the motor and receives air from a flexible air inlet tube that is slidably engaged to the motor and is secured to the tool's handle portion.
