North American Carbide CBN (Polycrystalline Cubic Boron Nitride) Inserts Made In USA
What Is CBN? Polycrystalline Cubic Boron Nitride (CBN) is an artificially synthesized material for cutting tools with a higher heat rating, a cost effective alternative to and exceeded in hardness only by diamond, while still offering superior wear resistance to carbide in certain applications along with a chemical resistance that’s better than PCD.
COMMON APPLICATIONS FOR CBN:
Alloy Steels
Carbon Tool Steels
Die Steel 
High Speed Steel
Forged Steel
Chilled Cast Iron
Meehanite Iron
Moly Chrome Steel Rolls
Inconel
