Machining Materials

• (H) - Hardened materials - Painted (Hardened Steel)

Chipbreaker

• (..MA) - Designed for machining brittle materials such as cast irons and painted steels. It has no geometry on the cutting edge. Suitable for heavy roughing **(roughing) in cast irons and light machining in painted steels.

Lathe inserts from Kyocera, a leading cutting tool manufacturer from Korea. The choice of the appropriate insert depends on the chipbreaker, i.e., the geometry that helps in breaking and removing the chip, as well as 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 life.
