Drill America GLBCO Series drill bit is manufactured to National Aerospace Standard 907. Made of heat resistant cobalt, They are especially effective in drilling tough, high tensile strength materials like PH stainless steel, Inconel, and titanium. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools. Round shanks allow use with a wide variety of tool holding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
