Vitrified Bond - Ceramic Oxide, Hardness Grade J
Ceramic mounted points in hardness grade J are manufactured from a mix of white aluminum oxide and blue ceramic sintered aluminum oxide in a vitrified bond.
The soft bond in combination with the easy to break down, sharp-edged white aluminum oxide and the self-sharpening effect of the microcrystalline sintered aluminum oxide allows extremely high stock removal rates with excellent tool life.
The hardness grade J is perfectly suited for surface work on titanium materials, nickel and cobalt based alloys, steel components and build-up weld deposits.
Advantages:
- Cool grinding due to the easy to break down grit mix.
- High stock removal and excellent tool life.
- The self-sharpening qualities of the sintered aluminum oxide guarantee consistent stock removal.
Mounted points in hardness grade J perform best at a cutting speed of 6,000 - 9,800 SFPM. Suitable tool drives include flexible shafts and electric or air-powered straight grinders.
