Abstract: The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material, prior to separating the continuous stock material into a number of discrete parts. The efficiency of the forming process is enhanced since individual parts need not be individually transported and oriented during the forming operations. By not requiring that the individual parts be separately transported and oriented during the forming operations, the quality of the parts formed by the forming method and apparatus of the present invention will also be enhanced since such separate transportation and orientation of individual parts generally increases the opportunities for misalignment and contributes to poor tolerance control during the manufacturing process.
