Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
Cobalt steel tools bear resemblance to high-speed steel, yet they contain a higher concentration of cobalt, enhancing their effectiveness in cutting tougher materials like stainless steel or nickel alloys.
Ideal for portable or machine drilling
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
