  • CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits
  • MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits
  • JOBBER LENGTH: 3/16-Inch cutting diameter, 2-5/16-Inch flute length, 3-1/2-Inch overall length, 135 degree split point, 3-flat shank
  • INCLUDE: 12 pieces of 1/8-Inch cobalt drill bits with case
  • APPLICATION: best used for drilling in hard metal, including stainless steel
  • CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits
  • MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits
  • JOBBER LENGTH: 1/8-Inch cutting diameter, 1-5/8-Inch flute length, 2-3/4-Inch overall length, 135 degree split point, straight shank
  • Made in USA
  • Made of steel with an epoxy finish and has a snap-lock cover for durability and protection
  • Labeled storage holes for identification and organization
  • Index holds 115 jobber length drill bits in fractional sizes 1/16" to 1/2" in 1/64" increments, letter sizes A to Z, and wire gauge sizes #1 to #60
  • Intended to be used on hard metals
  • No bit walking - more user control
  • Pilot point and split tip design
  • Designed for maximum speed and life
  • Manufactured to National Aerospace standard 907
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • Round shanks allow use with a wide variety of toolholding systems
  • 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
