Thread rolling is a great way to quickly and confidently create a quality thread. Thread rolling is a process of displacing the material into the shape of a thread. As this photo shows, thread rolling heads contain two or three internal disks. Used on both lathes and mills, the 3 disk unit is an axial head. The material is fed into the unit from the end.
