COMBINED THREAD ROLLING DIES ABSTRACT OF THE DISCLOSURE A die set consisting of three separate dies is disclosed, with the first die having thread forming ridges on both sides thereof and both sides being flat, i.e., the contact surface areas thereof lying in a single plane to engage a flat, planar die support surface in the die holder. Each of the second and third dies is a single-faced die with a flat, planar rear face to engage the die holder, and the working face of each of the second and third dies includes a longitudinally tapered portion and a parallel dwell portion for final finishing of the workpice. This effectively doubles the die life for only a fifty percent increase in die material. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all princi- ples of operation or applications, and is not to be con- strued as a limitation on the scope of the claimed subject matter.
