Drill America jobber length drill bit. Manufactured to National Aerospace standard 907. Made of heat resistant cobalt, they display higher red hardness which permits speeds upto 30 percent greater than High-Speed Steel drills and are especially effective in drilling tough, high tensile strength materials like PH stainless steel, inconel, and titanium.
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
I’ve used Drill America bits for many years. The M42 8% Cobalt specifically! I love them. For a couple extra bucks, the M42 Cobalts blow the M35 5% Cobalt Drills out the water. The standard HSS bits don’t even compare. The M42 Drills cut almost as good as Solid Carbide. Drill America is a great value. And their Drill Bits are super high quality’s straight & finished well. Fantastic!
