Abstract: A tool holder which uses a collet for holding a stationary tool on a turret of a turret lathe. The turret being of the type having a plurality of flat surfaces adapted for receiving a tool holder. The tool holder includes a body with a flat surface adapted for mounting against at least one of the flat surfaces of the turret, and a fixed aperture of a fixed size having an axis, a first end centered on the axis and a second end centered on the axis and a constriction starting near the first end and gradually reducing the size of the aperture in the direction of the second end. At least two locations for fixedly mounting the body against the turret are positioned next to the aperture, and allow for mounting of the body against the turret in a fixed position. Structure which allows the introduction of an axial load on the collet, the axial load being in the direction of the axis of the aperture, and which cooperates with the body, so that the axial load radially collapses the collet when the collet is mounted in the aperture, and so that the tool to be attached to the turret lathe is gripped by the collet.
