FRKSMD-1/4" Cobalt Steel Taper Length Drill Bit, DWDTL Series

Designed for drilling where a length longer than jobber length is requiredCobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or el alloysGold 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 systemsWhen run in a counterclockwise direction (right-hand cut) spiral fluted tools cuate chips up and out of the cut to reduce cloggingIdeal for drilling in tough, high tensile strength materials
