Drill America TSD Series M42 Cobalt Steel Long Length Drill Bit, Gold Oxide Finish, Threaded Shank, Spiral Flute, 135 Degrees Split Point, 10 Size (Pack of 25)

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
