Slugger CBN Cutting Tools

what is CBN?

Cubic boron nitride (CBN) is the second hardest material after synthetic diamond and is synthesised from hexagonal boron nitride under conditions similar to those used to produce synthetic diamond from graphite. The desirable characteristics of an abrasive include high hardness, strength, abrasion resistance, and thermal and chemical resistance, and an ability to maintain sharp cutting edges during use. These characteristics exceed the values of conventional abrasives, such as silicon carbide and aluminum oxide. In particular, the properties of high thermal stability and chemical resistance make it suitable for machining ferrous materials, an area where synthetic diamond abrasives are not normally employed.

Slugger Imported E6 Material CNC SCGW PCD Tips

(Cubic Boron Nitride) CBN Cutting 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
