  • It is recommended to regrind 3-5 times.


Feature Advantage:

  • Straight grooves and spiral grooves are available for different materials to be processed.
  • For different equipment, there are internal and external cooling options.
  • The ultra-fine alloy matrix with good strength, toughness and wear resistance combined with the nanostructured TiAlN coating optimized for drilling ensures the high toughness and strength of the tool.
  • The unique coating process gives the tool a smooth surface and extremely high wear resistance.
  • Outstanding thermal stability and chemical stability provide effective protection for the cutting edge.
  • Customized sizes according to customer requirements.


Technical Information:

  • Typical application of solid carbide drills:
    • Small diameter hole
    • Tight or precision tolerance hole
    • The hole shorter than a deep hole
  • Chip formation and chip evacuation are important issues in drilling. It depends on the workpiece material, blade geometry selection, coolant pressure, capacity, and cutting parameters.
  • Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.
  • The drill bit is mounted on the shank chuck and its circumferential runout must be less than 0.02 mm.
