#28 Cobalt Short Threaded Shank Drill Bit Overall Length 1-1/4, TSD Series

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
  • Threaded shank is for use with threaded-spindle tools, often used in aerospace and automotive applications
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • Featured with 135 degrees heavy duty split point and surface treated for drilling hard, tough, high tensile strength materials
