Lathe inserts from Dormer Pramet, a leading cutting tool manufacturer. The choice of the appropriate insert depends on the chipbreaker, that is the geometry that helps in breaking and removing the waste, as well as on the grade, which describes the microstructure and coating of the insert and directly affects hardness and brittleness. The cutting conditions (speed, feed, depth) must be carefully defined to achieve maximum tool performance and lifespan.
