PFERD vitrified bond Ceramic mounted points in hardness grade J is 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 service life. The hardness grade J is perfectly suited for surface work on titanium materials, nickel and cobalt-based alloys, steel components and buildup weld deposits. Application: Re-finishing of airplane turbine blades. Follow-up repair welding in tool and mold construction. Grinding of repair welds and turbine blades. Pferdefficiency - recommends mounted points in hardness grade J for long, fatigue free and resource saving work, with perfect results in the shortest possible time.
