CBNGRADES CBN
A 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 cutting.
FEATURES
• S uperior wear resistance when cutting hardened materials
• S uitable for high speed cutting of cast iron and sintered steel
• H igh thermal conductivity provides stable cutting
