Patent ID: 7722438

Claim:
A pneumatic tool that is powered by compressed air, for working on a workpiece and removing debris from the workpiece, comprising: a tool piece that performs work on a work area of the workpiece, wherein said tool piece defines a rotary axis that perpendicularly extends from a mounting disc; and an air blow device that directs the compressed air to a non-work area of the workpiece to remove debris from the non-work area, the air blow device including an air blow inlet fluidly connected to a manifold and an air blow supply line, wherein the manifold is supplied the compressed air from a main inlet, and wherein the air blow supply line fluidly connects the air blow inlet and an air blow valve with an actuating button, and the actuating button allows selective fluid communication between the air blow supply line and a nozzle of straight hollow pipe construction that expels the compressed air toward the non-work area, wherein the nozzle is generally perpendicular to the rotary axis of the tool piece, and the air blow device operates independently of the tool piece.
