SUMIBORON BN1000 / BN2000

Feature

Realizes steady tool life with excellent breakage and wear resistance.

Uncoated SUMIBORON grades that utilize a newly developed high-purity ceramic binder.
Combines both fracture and wear resistance to achieve a stable tool life in a wide variety of hardened steel machining.
A wide selection of inserts are available, starting from a single-cornered type.

BN1000

SUMIBORON grade for high-speed machining with the best wear resistance

Providing superior tool life in continuous cutting to light interrupted cutting.

Improved fracture resistance while emphasizing wear resistance.

Improved hardness and thermal resistance from the high-purity TiCN ceramic binder.

BN2000

General-purpose grade suitable for typical hardened steel machining applications.

Provides stable tool life in continuous to light to medium interrupted machining.

Has a high degree of both fracture and wear resistance.

Significant improvements in the performance of both by employing a high-purity ceramic binder.

Stable surface roughness achieved by increasing edge sharpness.
