Drill America - D/AMMCO18.00 18.00mm Cobalt Metric Drill Bit, D/AMMCO Series

Product description

• 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 toolholding systems.
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
• Manufactured to National Aerospace standard 907.
