CBN Tools

Cubic Boron Nitride (CBN) Tools used for hard machining applications. These tools are rated second when comparing hardness properties, just below PCD Tools and are used for machining most steels and cast iron. Other characteristics of CBN are its abrasion resistance, thermal and chemical resistance and maintaining sharp edges when cutting – which are most effective when machining ferrous materials.

Typical applications and industries that use CBN Tools include:


Hardened Steels
Gray Cast Iron
Hard Cast Iron
Powder Metal Materials
Hard Facing Alloys
Thermal Spray Ni Based
Thermal Spray Co Based
