  • THREAD REPAIR INSERT AND METHOD OF USE
    Publication number: 20190277327
    Abstract: A thread repair insert system having a cylindrical body that extends from an upper end to a lower end and includes a threaded exterior surface and a hollow interior having a threaded interior surface. The lower end of the cylindrical body includes a cutting section that includes a plurality of notches that separate threaded sections. The threaded sections include a cutting edge followed in the direction of rotation by a trailing edge. The lower end also tapers or narrows slightly such that the threaded sections transition from partial threads to full threads as they extend upward. As the thread repair insert is rotated into an opening in parent material, the cutting edge cuts material which is forced between the threads of the threaded sections. As the threaded sections transition from partial threads to full threads in the threaded sections, threads are roll-formed in the parent material.
