      THREAD MILLING  There are several methods used for thread milling operations. The cutter usually rotates clockwise, except in

                 special cases where the tool rotates counterclockwise. The spiral movement of the cutter can be clockwise or
                 counterclockwise, and the tool can produce a thread by top-down or bottom-up. The combination of these
                 movements depends on the type of thread required to produce; left-hand or right-hand threads.
