Drill America 15 Piece m35 Cobalt Drill Bit Set (1/16" - 1/2" x 32nds), DWDCO Series

Product description

• 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
• 15 piece drill bit set comes in a metal case
