Benefits of Thread Mills Left- and right-handed threads Thread mills are not left-hand or right-hand specific. While the thread mill is interpolating, the thread mill must move up or down one 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.
