Features and benefits

  • High positive chipbreaker geometry preferred on ductile and normal chipping materials at medium feed rates.

  • Preferred on inboard position.

Grades

  • KC7025

    PVD-Tin coated fine grade carbide
    Excellent wear resistance and toughness
    First choice for stainless steel, titanium, and super-alloys
    Interior cutter for DRILL-FIX DFR
    For difficult machiningrequirements

  • 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.

    M
  • KC7225

    Composition: PVD TiAlN coated fine-grain carbide with enhanced toughness.

    Application: Best suited for machining of most materials. This grade offers excellent process reliability in metastable conditions due to enhanced carbide toughness. The TiAlN coating improves wear resistance for use at intermediate cutting conditions.

    K
  • KCPK10

    Composition: Advanced TiCN-Al2O3-CVD coating combined with a cobalt-enriched carbide substrate, this grade offers a balanced combination of deformation resistance and edge toughness.
    Application: KCPK10 offers outstanding abrasion and crater wear resistance for high-speed machining of steels and cast irons. Use for very high cutting speeds with low to medium feed rates.

    K
  • KCU25

    Turning Composition: An advanced PVD grade with hard AlTiN coating and fine-grain unalloyed substrate. The new and improved coating improves edge stability with wide range speed and feed capabilities.

    Turning Application: The KCU25 grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cut and high feed rates.

    Holemaking Composition: Advanced CVD TiCN-Al2O3 coating combined with a tough carbide substrate.

    Holemaking Application: First choice for steel, stainless steel, and cast iron. This grade offers adequate deformation resistance, excellent edge strength, and superior wear resistance over a wide range of machining conditions for high productivity with very good reliability.

    K
  • KCU40

    Composition: Multilayered TiN-TiAlN-PVD coating and a tough substrate, that withstands interruptions and provides high wear resistance for long tool life.
    Application: KCU40 is the first choice for high reliability in most materials. This grade should be used at medium speeds and high feeds due to sharper edges. KCU40 covers steel, stainless steel, cast iron, and high-temperature alloys for high toughness applications under certain conditions.
