Manufactured to National Aerospace standard 907. Made of heat resistant cobalt, they display higher red hardness which permits speeds upto 30% greater than high speed steel drills and are especially effective in drilling tough, high tensile strength materials like PH stainless steel, inconel, and titanium. The 135 degree split point is self-centering and reduces thrust. Sizes smaller than 1/16 have the 118 ° standard point. 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. All Electronics in 120V USA. Will not work in other countries without adapters and transformers. The item “Drill America D/ACO Series Cobalt Drill Bit Set in Metal Case 13 115 Piece” is in sale since Saturday, July 28, 2018.
