Abstract: A shave tool holder for use with an automatic screw machine and for machining a rotatably driven workpiece. The tool holder includes a shank engageable with the screw machine and for providing reciprocating motion of the shave tool holder. A dovetail shaped recess is defined within a forward mounting portion of the shank and a corresponding dovetail shaped projection in an opposing surface of the body in order to engage the body with the shank in a vertically deflectable and adjustable manner. A roller is secured in vertically adjustable fashion to a forward facing location of the body. A tool post is releasably secured to the body, through aligning apertures formed in the body and the tool post, a mounting bolt inserting through the aligning apertures for securing the tool post to the body. A cutting insert is secured upon the tool post in a desired spaced relationship relative to the roller and so that the rotatably driven workpiece is adapted to being received between the roller and the insert.

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.
