    Bordo TiAlN Coated Jobber Drill WHITE BAND CAST IRON
    A highly abrasive material with damping and thermal conductivity, high strength and resistance to wear. Cast Iron is used extensively for mass produced components.
    The Bordo White Band Series is designed for this specific purpose.

    TiAlN coating increases tool surface hardness to 87Rc. For machining materials with Hardness < 300 HB : Tensile Strength <1000 N/mm2.

    DRILL BIT SURFACE TREATMENT TiAlN (Titanium Aluminium Nitride) VIOLET / GREY
    A violet/grey finish with a higher hardness than both TiN and TiCN coating utilises aluminium in the coating which imparts greater oxidation stability. This stability is a result of a very thin film of Aluminium Oxide which is formed on the surface of the TiAlN. This film is self repairing which leads to increased tool service life. This high performance coating is able to withstand much higher temperatures which allows increased speeds and feeds and semi-dry machining operations. TiAlN coating is especially useful when machining cast iron and tough steels
