    摘要: The invention pertains to a tooling apparatus that facilitates the positioning of a work piece in a particular angular configuration with respect to a longitudinal axis of the securing surface. The tooling apparatus comprises a substantially rectangular body having a one or more steps embedded along the length of an inner facing surface. In practice, the present invention tooling apparatuses mounted typically to the hard jaw of a machining vice. The present invention apparatus body can be manufactured from a variety of metallic or polymeric materials. If there are more than one step, then the steps are arranged to be a fixed distance between each step. The tooling apparatus haves the function to facilitate the mounting of work pieces in a vice for performing precise milling, grinding cuts or drilling operations ninety degrees perpendicular to the longitudinal or horizontal axis of a machining vice.
