CBN A Insert Grades
CBN
KYOCERA CBN is second only to diamond in hardness. CBN (Cubic Boron Nitride) is a
synthetically produced material with high thermal conductivity which provides stable machining.
Features
• Superior wear resistance when machining hard materials
• Suitable for high speed machining of cast iron and sintered steel
• High thermal conductivity provides stable machining
