Both cresting and non-cresting partial profile inserts are specifically designed for either external or internal threading operations. Cresting inserts provide a fully controlled thread form, including diameter for a given pitch. The need for deburring is eliminated and the inserts are optimised for the best tool life at that pitch. Non-cresting partial profile inserts offer the flexibility to cut a variety of thread pitches with one insert. Right-hand Laydown Threading toolholders use right-hand inserts. Left-hand Laydown Threading toolholders use left-hand inserts. Right-hand Laydown Threading boring bars use right-hand inserts. Left-hand Laydown Threading boring bars use left-hand inserts.
