CUBIC BORON NITRIDE (CBN)
CBN-5
Bright black powder with less than 2% of semitransparent and/or whitish crystals. CBN-5's consistent blocky, sharp
edged crystal shape make this ideal crystal for precision hardened steel grinding applications. The uncoated CBN-5
crystal is best suited for Electroplated and Vitreous bond grinding wheel systems.
