Grades

  • KB1345

    Composition: A high CBN content, PCBN tip brazed onto a carbide insert.
    Application: Applied in roughing to finishing of fully pearlitic grey cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Also use for finishing chilled cast iron and fully pearlitic cast iron. The tipped PCBN insert is available in a wide range of insert styles including positive rake geometries that are ideally suited for boring applications.

  • KB1610

    Composition: A low CBN content, PCBN tip brazed onto a carbide insert.
    Application: 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, carburised and nitrided irons, and some hard coatings. Do not apply on soft steel.

  • KB1630

    Composition: A high CBN content, PCBN tip brazed onto a carbide insert.
    Application: Designed for roughing to finishing in interrupted cuts on hardened steels (>45 HRC). It can also be applied on grey cast iron, chilled irons, high-chrome alloyed steels, and sintered powdered metals. The tipped PCBN insert is available in a wide range of insert styles, including positive rake geometries, that are ideally suited for boring applications.

  • KB5610

    Composition: A low content PCBN grade with a PVD TiAlN coating for added wear resistance.
    Application: Designed for the precision machining of hardened steels (>45 HRC). The PVD coating offers improved wear resistance and excellent surface finish capabilities. It can be very effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburised and nitrided irons, and some hard coatings. Available in a multitip format with a tremendous breadth of edge preps, insert styles, and wiper geometries.

  • KB5625

    Composition: A PVD TiAlN coating over a medium content, PCBN tip brazed onto a carbide insert.
    Application: 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, carburised and nitrided irons, and some hard coatings.

  • KB5630

    Composition: A high content PCBN grade with a PVD AlTiN coating for added wear resistance.
    Application: Designed for roughing to finishing in hardened steels (>45 HRC), abrasive workpiece materials such as sintered valve seat materials, powder metallurgy tool steels, and hard high-alloy cast irons. The PVD coating provides resistance to crater wear and increased resistance to chipping. The tipped PCBN insert is available in a wide range of insert styles, including positive rake geometries, that are ideally suited for boring applications.

  • KBH10

    Composition: A low content PcBN grade with a patented binder structure.

    Application:Designed for the precision machining of hardened steels (>45 HRC).  It can be 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.  Available in a multi-tip format with a wide range of edge preps, insert styles, and wiper geometries.

  • KBH20

    Composition: A low content PcBN grade with a PVD TiN/AlTiN coating for added wear resistance.

    Application: KBH20™ is the ideal PcBN hard turning grade for continuous to lightly interrupted cutting applications. The structure, as well as the different edge preparations, enable repeatable workpiece tolerances, excellent surface finishes, and surface integrity. Typical applications are case-hardened steel components such as gears, shafts, and other drive-train components.
