Abrasives > Mounted Points | Pferd Mounted Point W Shape Ceramic Blue J Hardness | Pferd Mounted Point W Shape Ceramic Blue J Hardness | W Shape Ceramic - Blue - J Hardness | Mounted points in hardness J are manufactured from a vitrified bond and a grain mix of white aluminium oxide and blue ceramic. | The soft bond in combination with the easy-tobreak-down, sharp-edged white aluminium oxide and the self-sharpening effect of the microcrystalline ceramic oxide grain allows extremely high stock removal rates with excellent tool life. The hardness J is perfectly suited for surface work on titanium materials, nickel- and cobalt-based alloys, hardened steel components and built-up weld deposits. | Advantages | Cool grinding due to the easy-to-breakdown grain mix. | High stock removal rate and very long tool life | Constant stock removal through self-sharpening qualities of the ceramic oxide grain | Application examples | Re-finishing of turbine blades during aeroplane maintenance work | Follow-up repair welding in tool and mould construction | Grinding of repair welds on turbine blades | Recommendations for use | Mounted points of hardness J achieve their best performance at a cutting speed of 30 to 50 m/s | Flexible shafts, electric grinders and airpowered straight grinders are suitable as tool drives |
