Drill America DWDCO30P12 #30 Cobalt Drill Bit (Pack of 12), DWDCO Series

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.
Ideal for drilling in tough, high tensile strength materials.
