Description
Tool Sharpening - Special Application Mounted Points

Choose from a mounted point that has a J or K 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


Mounted points in hardness K are manufactured from a grain mix of pink aluminium oxide and regular aluminium oxide in a vitrified bond.

In a medium-hard bond, this abrasive grain combination leads to a good stock removal rate and a long tool life. The hardness K is particularly suitable for general use on cast iron parts when used with high peripheral speeds.

Advantages:
- Suitable for use on surfaces and edges
- High abrasiveness and long tool life
- High stock removal rate due to coarse grit sizes

Application examples:
- Cleaning of workpieces made from grey and nodular cast iron
- Grinding out of shrinkage holes in grey and nodular cast iron components

Recommendations for use:
- Mounted points of hardness K 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
