Product Features
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
Customer Reviews
These bits have been terrific for me. Drilled out a bunch of stainless steel pop rivets, no problem. These can be tough. Bit seemed sharp as day one. Also drilled many holes on a curved aluminum piece. Bit didn't walk ... drilled just where I wanted ...Very happy with this purchase!
