Applications

  • Cobalt offers better wear resistance, higher hot hardness & toughness when compared to high speed steel.
  • Cobalt also provides less chipping under severe cutting conditions allows tool to be run 10% faster than high speed steel.
  • Primarily designed as tools for heavy duty drilling of larger holes requiring reduced diameter straight shank drills.
  • Suitable for most drilling operations in a wide array of materials having low and medium tensile strength ratings.
  • Intended for those applications where only a 1/2" chuck is available to drive the drills.
  • May be used with a wide range of portable or stationary machine tools and with hand held manual drills.
  • For optimal performance and the best tool life suitable lubricating/cutting oils or the appropriate coolant fluids are recommended.
