When operated in a counterclockwise rotation (right-hand cut), spiral fluted tools remove chips by directing them upward and away from the cut, minimizing clogging.
Manufactured to national aerospace standard 907
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
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
Sizes included are 9/16", 5/8", 3/4", 7/8" and 1" with 1/2" reduced shanks
