TOUGH mounted points

For universal use on materials that are difficult to machine

The TOUGH type is specifically designed for use on titanium materials, nickel-based and cobalt-based alloys, hardened steel components and built-up weld deposits. Its applications include weld dressing on repair welds and reworking on turbine blades during aircraft maintenance, as well as regrinding of repair welds in tool and mould-making.

TOUGH-type mounted points consist of a vitrified bond with an aluminium oxide mixture of ceramic oxide grain and white aluminium oxide.


  • Cool grinding as the grain mixture is easy to break down.
  • High stock removal rates and very good tool life.
  • Constant stock removal rates thanks to the self-sharpening qualities of the ceramic oxide grain.


  • Hardened, heat-treated steels over 1,200 N/mm² (> 38 HRC)
  • Titanium alloys
  • Titanium
  • High-temperature-resistant materials
  • Nickel-based and cobalt-based alloys

Application tips

  • TOUGH mounted points perform best at a cutting speed of 30 to 50 m/s.
  • Mounted points should be used with a flexible shaft drive or a straight grinder.
  • TOUGH mounted points are used for tool and mould-making as well as engine and turbine construction.
  • TOUGH mounted points should be used with an adjusted contact pressure.
  • Use dressing stones for profiling and dressing.
  • Use coarse grit sizes for stock removal and rough grinding. Use fine grit sizes for fine grinding.
