Why is cubic boron nitride better than diamond for grinding HSS?
• Crystals of boron nitride stand up to the heat of grinding better than diamond and can be used at high speeds on a normal bench grinder • Diamond grit can react chemically with steel during grinding which dulls the diamonds • Boron nitride does not react with steel in this way so stays sharp and cool cutting • Boron nitride is nearly as hard as diamonds and is much harder than aluminium oxide abrasive • Boron nitride grit is tougher and stronger than diamond crystals so will survive the stress of grinding woodturning gouges Cubic Boron Nitride grinding wheels in our online shop Buy a CBN wheel
