Workpiece Material


Features and benefits

  • General purpose chipbreaker geometry preferred on ductile and normal chipping materials.

  • Preferred on outboard position.


  • KC7020

    PVD-TiN coated fine grade carbide
    Highly Wear Resistant, very high level of edge strength
    Particularly for the DRILL-FIX DFR external insert
    First choice for stainless steel
    Also for super-alloys and titanium

  • 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.

  • KC7315

    • Multilayer TiAlN-PVD-coated universal fine-grain grade.
    • Highest level of wear resistance for higher cutting speeds.
    • More efficient than TiN-PVD grades.
    • First choice for alloyed and high-alloy steel and cast iron.

  • KC7815

    Multi-Layered MT-CVD TiCN-Al203 coating
    Designed for indexable drilling of alloyed steels and some cast irons
    Superior performance when drilling ferrous steels at elevated speeds
    Expect 100% improvement in tool life versus competitive grades
    Use KC7815 in outboard pockets, KC7140 in inboard pockets for optimum performance with DRILL-FIX bodies
    Geometry: GD with honed negative land provides added strength

  • 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.

  • 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.

  • 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.
