Recommended Application

Stable, long tool life trump card for cost reduction

Inserts for high-efciency machining also available.

One-use insert Break-master with chipbreaker FV type for light cutting and LV type for finishing added to series.

 

BNC2010

A grade for high-precision machining applicable to finishing requiring good surface roughness and dimensional accuracy.

Provides further improved wear resistance thanks to a newly developed CBN substrate coated with a TiCN layer.

Reduces boundary wear and stably achieves excellent surface finish thanks to newly developed special multi-layered coating.


BNC2020

A general-purpose grade applicable to general hardened steel machining.

A newly developed tough CBN substrate coated with a highly wear-resistant TiAlN layer.

Achieves more stable machining and longer tool life by employing a highly adhesive layer to reduce delamination.
