Complete range on PCBN turning inserts

PCBN (Polycristaline-Cubic-Boron-Nitride) is not found in nature, it is a synthetic material which is the result of an high temperature and high pressure process (HTHP). When PCBN tips are brazed to a carbide insert a powerful cutting tool is born. PCBN insert excel in the finishing and semi-finishing process of hardened steels (45-68 HRc) as well as hard cast iron and heat-resistant super alloys (HRSA).
