      Grades

      • CW5025

        Silicon-nitride ceramic. Extraordinary toughness properties. Roughing, also in heavily interrupted cuts.
        Capable of high-performance turning. To be used with or without coolant. For gray cast iron.

        K Cast Iron
      • HK1500
        P Steel
        K Cast Iron
      • THM

        Uncoated carbide. Extraordinarily good balance of hardness, wear resistance, edge stability, and toughness. Light and medium machining. For cast iron and all non-ferrous metals and non-metals. Useful in unfavorable conditions.

        S High-Temp Alloys
        N Non-Ferrous
      • THM-X
        S High-Temp Alloys
        N Non-Ferrous
      • THMF-X
      • TN20K

        Coated carbide. MTCVD-TiN-TiCN-Al2O3-TiN. Great when used for straight or lightly interrupted cut applications of ductile and cast irons.

        P Steel
        K Cast Iron
      • TN5015
      • TN5020
      • TN5105

        Coated carbide. MT-CVD/CVD — TiN-TiCN-Al2O3. Increased wear resistance for long tool life at high cutting speeds. Enhanced edge strength against depth-of-cut notching in interrupted cuts.

      • TN5120

        Coated carbide. MT-CVD/CVD – TiN-TiCN-Al2O3. Light and medium machining. For cast irons.

      • WBH25U

        A low CBN content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing of hardened steels (>45 HRC) where optimal surface finish is needed. Use in continuous to interrupted cutting of bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings.

        H Hardened Materials
      • WBK40U

        A high-content CBN, solid CBN insert with multiple cutting edges. Applied in roughing to finishing of fully pearlitic gray cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Use for finishing chilled and fully pearlitic cast iron. Solid inserts offer better security and shock resistance than tipped inserts, while also enabling deeper depth-of-cut capability.

        K Cast Iron
      • WK05CT

        Coated carbide. MT-CVD/CVD — TiN-TiCN-Al2O3. Increased wear resistance for long tool life at high
        cutting speeds. Enhanced edge strength against depth-of-cut notching in interrupted cuts.
