A tool for cleaning slivers and the like from a surface of a workpiece, such as the bushing of a chain drive track. In one form, the tool includes structure defining a manifold having an opening and arranged to be abutted to the workpiece with the opening juxtaposed to the workpiece surface on which slivers and the like may be deposited. Fluid, such as air, under pessure is delivered into the manifold and directed substantially directly against the juxtaposed workpiece surface to entrain the slivers and other foreign matter on the prelubricated surfaces. A suction is applied to the manifold for sucking the excess fluid and the entrained slivers and other material outwardly from the manifold. In another form, the manifold is movable against complementary wall surfaces to define a chamber in which the workpiece is disposed. Movement of the manifold to and from the wall surface may be effected by suitable powered mechanism. In each form, the tool is particularly adapted for removing chips and slivers from workpieces wherein one element has been joined as by pressing to another. Preferably, the suction applied to the manifold is greater than the force of the pressurized fluid so as to assure removal of the slivers and other foreign material dislodged from the workpiece surface by the high pressure air.
