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.
