Drill America DWDCO30P12 #30 Cobalt Drill Bit Features
-
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
