      Grades

      • WBH10C

        A low content CBN grade with a MT-CVD/CVD — TiN-TiCN-Al203-TiN coating for protection against crater wear. Designed for precision machining of hardened steels (>48 HRC), effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings. Do not use on soft steels.

      • WBH10P

        A low content CBN grade with a PVD-TiAlN coating for added wear resistance. Designed for precision machining of hardened steels (>45 HRC); the harder the steel the better. PVD coating offers improved wear resistance and excellent surface finish capability. Effectively applied on bearing steels, 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
      • WBH10U

        A low CBN content, CBN tip brazed onto a carbide insert. Designed for precision finishing in smooth cuts on hardened steels (>45 HRC) where optimal surface finish is needed. Use on bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings. Do not apply on soft steel as rapid crater wear will result.

        H Hardened Materials
      • WBH20P
        H Hardened Materials
      • WBH25P

        A PVD-TiAlN coating over a low content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing of hardened steels (>45 HRC). Use on 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
      • 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
      • WBH30P

        A PVD-TiAlN coating over a low content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing in interrupted cuts on hardened steels (>45 HRC). Applied on gray cast iron, chilled irons, high-chrome alloyed steels, high-temp alloys, and sintered powdered metals.

        H Hardened Materials
      • WBK45U

        A high CBN content, CBN tip brazed onto a carbide insert. 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. Available in a wide range of insert styles, including positive rake geometries ideally suited for boring applications.
