what machine is used to grind cobalt

  • Cobalt Steel Cutting Tools | Regal Cutting Tools

    Cobalt steel is a variation of high speed steel with a higher content of cobalt. Common grades are M-35 and M-42, having 5% and 8% respectively. These steels are ideal for cutting tools because they have a high red hardness that gives it much higher heat resistance. This allows tools made of cobalt to be run at faster speeds and higher feed rates.
