    Bordo Bright Jobber Drill YELLOW BAND ALUMINIUM
    The alloying elements which are used to create the myriad of Aluminium Alloys have an effect on the machining properties of the resulting materials. This generally creates a difficult long chip form, which tends to stick to the tool, placing a unique set of demands on tooling.
    The Bordo Yellow Band Series contends with these difficulties.

    For machining materials with Hardness < 200 HB : Tensile Strength <700 N/mm2.
