      Features and benefits

      Kennametal stocks a complete line of standard inserts for wheel and axle machining. Inserts are available in various styles, sizes, and grades.

      • Wheel boring — molded chipbreaker inserts in round, square, octagon, and regrindable inserts.

      • Axle turning — triangle- and diamond-shaped inserts with chipbreakers.

      • Wheel turning — rectangular and square styles, with or without molded chipbreakers.

      • Wheel turning — round buttons with center hole for locking.

      • CM5
      • CW2
      • KC850

        composition: A CVD tri-phase coating on an extra-strong, cobalt-enriched
        alloyed substrate.
        application: Designed for heavy cutting of low-, medium-, and high-carbon
        steels, medium hardness alloy and tool steels, stainless steels, and some
        high-temperature alloys. Excellent thermal and mechanical shock resistance
        makes grade KC850 ideally suited for difficult drilling applications.
        Used in inserts for Kendex/Metcut drill bodies.

        M Stainless Steel
      • KC9010
      • KC9105

        composition: An innovative, highly deformation-resistant cobaltenriched
        substrate (patent pending) with a new thick multilayer
        MTCVD-TiCN-Al2O3-TiCN-TiN coating for maximum wear resistance.
        application: KC9105 is the latest addition to the KENNA PERFECT
        grades for finishing to medium machining of most steels, ferritic,
        martensitic, and PH stainless steels and cast irons The specially
        designed substrate provides a remarkable combination of deformation
        resistance and insert edge strength. The extra-thick MT-TiCN layer
        provides outstanding flank wear resistance, while the thick Al2O3
        layer offers excellent crater wear resistance and speed capability.
        A state-of-the-art post-coating treatment results in a smooth insert
        surface that reduces microchipping and build-up and improves
        workpiece surface finish.

      • KC9125

        Composition: A tough cobalt-enriched carbide grade with a newly designed multilayer K-MTCVD TiCNAl2O3-TiCN-TiN coating with superior interlayer adhesion.
        Application: General-purpose turning grade for most steels and ferritic and martensitic stainless steels. The substrate design ensures adequate deformation resistance along with excellent bulk toughness and insert edge strength. Coating layers offer wear resistance over a wide range of machining conditions and reduce frictional heat, minimise microchipping, and improve workpiece surface finishes. Performs well in moderately heavy roughing to semi-finishing cuts. Use the KC9110 grade for finishing cuts.

      • KC950

        KC950

      • KCP25B

        Composition: A tough cobalt-enriched carbide grade with a newly designed multilayer MTCVD-TiCN-Al2O3-TiOCN coating with superior interlayer adhesion.

        Application: Best general-purpose turning grade for most steels and ferritic and martensitic stainless steels. The substrate design ensures adequate deformation resistance with excellent insert edge strength. Coating layers offer good wear resistance over a wide range of machining conditions and the post-coat treatment minimises microchipping and improves coating adhesion to substrate leading to long tool life and improved workpiece finishes.

        P Steel
        K Cast Iron
      • KCS10

        Composition: An advanced PVD-AlTiN coated, fine-grained tungsten carbide grade.
        Application: The KCS10 grade specifically engineered for the productive machining of high-temperature alloys. The fine-grained tungsten carbide substrate has excellent toughness and deformation resistance while the advanced PVD coating allows metalcutting speeds double those of conventional PVD-coated cutting tools.
