[57] ABSTRACT
A shave tool holder having a body, a platform base and a vertically extending superstructure. An elongate shank portion extends from the body and mounts the body to a holder block. The holder block is reciprocally actuated in a horizontal direction in combination with being pivotally actuated in a vertical direction. A cutter insert is releasably secured upon the platform base. A roller is mounted to a support portion which is in turn secured to the vertically extending superstructure. The roller and support portion are capable of being vertically actuated up and down along the superstructure by a bolt. The enlarged head portion includes a plurality of radially outwardly extending markings corresponding with a circumferential array of the enlarged head portion. The enlarged head portion is capable of being rotatably engaged to adjust a selected marking in aligning fashion with a further reference marking extending from the tool holder body and to establish a desired minimal distance between an exterior facing surface of the roller and the cutter insert, the minimal distance corresponding to a desired outer diameter sizing operation of a rotating workpiece. In operation, the roller is upwardly actuated by the rotating workpiece and the cutting tool is brought into contact with the workpiece upon forward reciprocation of the holding block, the holding block being reverse reciprocated to withdraw the body from the machined workpiece.
