Kyocera Coated CBN for Machining Hardened Material – KBN015

Kyocera

New Coated CBN for Machining Hardened Material

KBN015

1st recommended grade for general purpose machining of high hardness material. “Wear resistance + Fracture resistance” lowers costs when machining hardened material.

Features

  • Three grades are available for a wide range of hard materials machining.
  • KBN015: Our first recommendation for general-purpose machining. Suitable for a wide range of applications, from continuous to interrupted cutting and high-speed machining. KBN010 : Suitable for high speed and high precision machining, provides excellent surface finish quality. KBN020: Supports heavy interrupted cutting with high fracture resistance.
  • Unique Coating “MEGACOAT TOUGH” and New CBN substrate for Long Tool Life
  • “MEGACOAT TOUGH” coating with newly developed CBN dedicated high adhesion layer. High adhesion suppresses delamination for long tool life and stable machining
  • Product Lineup: KBN010 – High Speed – High Precision Machining; KBN015 – First recommendation for Medium – High Speed General Machining; KBN020 – Low – Medium Speed/General Machining

Deskripsi

KBN015 is a new-generation coated Cubic Boron Nitride (CBN) insert developed by Kyocera for high-performance machining of hardened steel, typically in the range of HRC 55–65. Engineered for superior wear resistance, thermal stability, and surface finish, KBN015 is ideal for continuous to light interrupted cutting applications such as finish turning of die steels, tool steels, and carburized parts.

The advanced multilayer TiCN + Al2O3 coating enhances performance by protecting the CBN substrate from oxidation and wear, thereby extending tool life and maintaining dimensional accuracy over longer cycles.

  • Excellent wear resistance for high-hardness steel machining (HRC55–65)

  • Multilayer coating (TiCN + Al₂O₃) for heat and oxidation resistance

  • Tough CBN substrate for stability in light interrupted cutting

  • Superior surface finish and dimensional control

  • Optimized for finishing to medium finishing operations

  • Stable edge strength for consistent performance
