THREAD MILLING - Allied Machine

Thread mills are not left hand or right hand specific. While the thread mill is interpolating, the thread mill must move up or down 1 pitch in the Z axis to create the thread's helix. If the Z axis is not moving, the thread mill will just produce grooves inside of the hole. No more ordering a special left handed tap. One thread mill provides
