      Grades

      • CD4

        CVD-TiN-TiCN-TIN multi layer coared carbide
        very tough
        Suitable for all steels (Alloyed and unalloyed)
        Particularly suitable for long-chipping tough steels

      • CM4

        CVD-TiN-TiCN-TIN multi-layer thick coated fine grade carbide
        High level of wear resistance
        Primarily for use on unalloyed carbon steels as well as alloyed steel and cast steel

      • CS5

        Composition: PVD TiN-coated grade with a sub-micron grain, straight carbide
        substrate containing 9.5% cobalt.
        Application: General purpose grade for drilling, countersinking, and counterboring
        operations in most steels, cast irons, and heat-resistant alloys. Good balance of
        toughness and wear resistance to provide all-around reliability.

        P Steel
        M Stainless Steel
      • KC7140

        Composition: PVD TiCN/TiN coated medium-grain carbide with high toughness.
        Application: Best suited for machining of steel and stainless steel. This exceptionally tough grade is perfectly suited for metastable machining conditions offering excellent tool life.
