Types of PVD Coatings

  • TiN

  • TiCN



    Chip and impact-resistant, TiCN coating works well for interrupted and low-to-medium speed cutting. It offers enhanced wear resistance to difficult materials like cast irons, copper, Inconel, and abrasive materials. The carbon adds hardness and surface lubricity.

    Color: Grey/Rose Brown
    Hardness: 3,100HV (Vickers Hardness)
    Service Temp: 850° F




    Based on nanolayers of Titanium and Aluminum, our AlTiN coating provides a low coefficient of friction and excellent toughness, combined with a high surface hardness. AlTiN is used on drills and milling cutters of steel and carbide for general applications and high-speed machining of ferrous materials with hardness up to 55-56 HrC.

    Color: Grey
    Thickness Range: 1 – 4 microns
    Hardness: 3200HV (Vickers Hardness)
    Maximum Operating Temperature: 1470° F
    Lubricity: 0.5 coefficient of friction

  • AICrN +4

    AICrN +4

    Our AICrN coating has a high aluminum content with the added benefits of CrN, which possess excellent wear resistance properties. This coating excels in dry machining applications, milling, drilling, and especially hard material machining at moderate or better speeds. Teamed with good wear resistance and increased heat resistance.

    Color: Anthracite
    Thickness Range: 1 – 4 microns
    Hardness: 3400HV (Vickers Hardness)
    Maximum Operating Temperature: 1830° F
    Lubricity: 0.3 coefficient of friction

  • AuRoRa



    From the AlCrN family and its benefits, AuRoRa has added impact resistance and durability for the interrupted cut environment. AuRoRa works very well in Turning, Milling, Drilling, Tapping, and Gear Cutting in Stainless Steel and Super Alloys.

    Color: Grey
    Thickness Range: 1 – 4 microns
    Hardness: 3400HV (Vickers Hardness)
    Maximum Operating Temperature: 1830° F
    Lubricity: 0.3 coefficient of friction

  • AITiSiN

    AITiSiN (Hardmill)

    Our latest coating STS-HARDMILL AITiSiN is a nanocomposite PVD coating. They are designed for hard, dry, and high-speed machining environments. HARDMILL exhibits exceptionally high resistance against oxidation and abrasion with a combination of high thermal hardness.

    STS-HARDMILL results from a special structural composition deposited in our high-performance PVD coating system. STS-HARDMILL properties yield significant advantages for the high heat demands placed on your cutting tools today.

    Color: Dark Bronze
    Thickness Range: 1 – 4 microns
    Hardness: 3500 HVO, 025
    Maximum Operating Temperature: 1200° F
    Lubricity: 0.5 coefficient of friction

  • ZRN

    ZrN Cutter

    ZRN (Mircal ALU)

    Our most biocompatible ceramic hard nitride, zirconium nitride, is tougher, harder, and more corrosion-resistant than titanium nitride. It is used extensively in cutting applications. ZrN is a less expensive alternative to diamond.
    Color: Light Gold
    Thickness Range: 1 – 3 microns
    Hardness: 2600 HV (Vickers Hardness)
    Maximum Operating Temperature: 600º C (1100º F)
    Lubricity: 0.35 coefficient of friction

  • TeTON



    This is our best offering for machining steels in demanding conditions. Designed for Steels TeTON excels in Turning, Milling, Drilling, and Tapping. TeToN has also performed very well in the Drilling and Milling of Stainless Steel.

    Color: Metal Bronze
