Hochleistungs-Vollhartmetallbohrer

Beyond Vollhartmetall-Tieflochbohrer • Großer Werkstoff-Anwendungsbereich • Innere Kühlmittelzuführung

Features and benefits
  • HP solid carbide deep-hole drills with through coolant for steel, cast iron, stainless steel, high-temperature alloys, and non-ferrous materials.

  • Application-specific SC drill for drilling holes up to 40 x D up to 4x faster than conventional HSS and gun drills.

  • Broadest diameter range on the market from .0938–.6299″ (2,383–16mm).

  • KMH-point geometry is available as a semi-standard, especially for crankshaft applications.

  • KCPK20™ grade (B27_HPG) is an AlCrN-TiAlN-based coating provides outstanding wear resistance. New ultra-fine-grain carbide ensures process reliability at high feed rates in steel and iron.

  • KN25™ uncoated grade (B27_HPS) with highly polished surface ensures superior chip evacuation and prevent built-up edge in aluminum and high-temp alloys, even when low-pressure coolant or MQL is applied.

  • KCMS20 grade (B27_SGL) is a monolayer PVD AlTiN coated ultrafine grain carbide with superior surface finish. First choice for deep hole drilling of stainless steel and high-temperature resistant materials. Due to the coatings enhanced high temperature properties this grade can also be applied for MQL applications in steel.

Grades

  • KCMS20

    Zusammensetzung: Ultrafeinkörniges Hartmetallsubstrat mit PVD-AlTiN-Einfachbeschichtung mit herausragender Oberflächengüte.

    Anwendung: Erste Wahl für Tieflochbohren in nicht rostenden Stählen und hochtemperaturbeständigen Werkstoffen. Durch ihre weiterentwickelten Eigenschaften für hohe Temperaturen eignet sich diese Sorte auch für die Bearbeitung von Stahl mit Minimalmengenschmierung.

  • KCPK15

    Zusammensetzung: Feinkörniges Hartmetallsubstrat mit PVD-TiN-TiAlN-Mehrlagenbeschichtung mit herausragender Oberflächengüte.

    Anwendung: Erste Wahl für legierte und hochlegierte Stähle sowie für Gusseisen. Die überlegene Oberflächenbeschaffenheit sorgt für exzellente Spanabführung und bietet zudem größtmögliche Verschleißfestigkeit bei verbessertem Zerspanungsvolumen.

  • KCPK20

    Zusammensetzung: Ultrafeinkörniges Hartmetallsubstrat mit PVD-Mehrlagenbeschichtung auf AlCrN-Basis mit herausragender Oberflächengüte.

    Anwendung: Erste Wahl für Tieflochbohren in Stahl und Gusseisen. Mit der von Kennametal entwickelten Beschichtung und der überlegenen Oberflächenbeschaffenheit bietet diese Sorte eine herausragende Verschleißfestigkeit sowie eine exzellente Spanabführung.

  • KN25

    Zusammensetzung: Unbeschichtetes, hoch verschleißfestes ultrafeinkörniges Hartmetallsubstrat.
