80A abrasive is a monocrystalline alumina abrasive, manufactured by the advanced technique.
Due to the extreme hardness and unique fracturing which generates many new cutting edges

SG abrasive is high purity, ceramic aluminum oxide abrasive with a submicron crystalline structure deprived from a
seeded gel sintering process.

employing abrasive, 80AA, and our advanced bond, V501, this eco-friendly internal grinding wheel offers equivalent or more grinding performance compared with sulfur treatment grinding wheels.

Our various vitrified bond CBN wheels will satisfy your applications and your needs.
