Drill America 5/16 Cobalt Stubby Threaded Shank Drill Bit Overall Length 5/8 TSD 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.
- Threaded shank is for use with threaded-spindle tools, often used in aerospace and automotive applications.
- When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
- Featured with 135 degrees heavy duty split point and surface treated for drilling hard, tough, high tensile strength materials.
