Coated CBN Inserts are engineered for high-performance machining of hardened steels, cast irons, and powder metallurgy materials.
The inserts feature a polycrystalline cubic boron nitride (PCBN) cutting x-layer — a composite of CBN particles bonded with TiC, TiN, TiCN, or AlN ceramic binders — firmly brazed onto a WC–Co carbide substrate for superior structural integrity.
Enhanced with advanced PVD coatings (C2, CE series), these inserts deliver outstanding wear resistance, thermal stability, and edge toughness, extending tool life by 50–100% compared with conventional CBN inserts.
Their optimized edge geometry and chip-breaking design enable efficient continuous and interrupted cutting, while maintaining excellent surface finish and dimensional accuracy.
Designed for precision machining in the automotive, bearing, and mold industries, WORLDIA PCBN inserts provide a reliable solution for achieving long tool life, stable performance, and reduced machining cost under demanding cutting conditions.
