Product Description
Drill America DWDCO40P12 #40 Cobalt Drill Bit (Pack of 12), 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
- Ideal for drilling in tough, high tensile strength materials
