BNC100 Hardened Steel

Coated Sumiboron premium grade

for high speed machining of hardened steels

General Features

Our copper coloured Sumiboron grade BNC 100 resists

premature plastic deformation of the cutting edge by

withstanding the high temperatures that occur when machining

hardened steels. This new grade features a heat resistant CBN

substrate and a special TiCN based ceramic coating to enhance

surface finish across a broad range of finishing applications at

elevated cutting speeds.

Ideal for higher speed machining and suitable for continuous or

light interrupted cuts BNC100 delivers reliable performance and

excellent tool life

Advantages High speed machining!

- l

Suitable for continuous to light interrupted high speed cutting with

vc = 150 ~ 300 m/min.

l Extended tool life!

Wear resistant ceramic coating and tough CBN substrate considerably extends tool

life.

l Excellent surface finish!

A consistent surface finish to values less than 6,3 Rz is easily achieved on both

continuous and light interrupted cut applications.
