Drill America - DWDCO5/8 5/8\ Reduced Shank Cobalt Drill Bit with 1/2\ Shank, 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.
- Manufactured to National Aerospace standard 907.
