Stable and consistent performance while machining of heat-resistant alloys.



  • Improved thermal properties help to reduce sudden fracture and decrease edge wear
  • Improved wear resistance with MEGACOAT HARD coating
  • New chipbreaker designs improve machining stability
  • PR005S: Hard, wear-resistant grade for high-speed machining
  • PR015S: General purpose grade with excellent wear resistance and stability




  • Newly developed substrate helps to reduce sudden fracture and notch wear
  • Finishing to medium machining = SQ chipbreaker
  • Roughing applications = SX chipbreaker



  • Machining of heat-resistant alloys
  • Finishing – medium - roughing
