Grinding Pins

Matrix Versions: Dry or Wet Pilot has developed specific matrices to give consistent self-sharpening properties for either air or water flushed grinding processes.

Crown Profiles: Pilot pins are available in several profiles to correspond with the geometry of the new button: Hemispherical (Round), Conical (Cone or Spike), Parabolic (Semi Ballistic), and Ballistic. The standard sizes for the crown profiles range from 6MM to 25MM (depending on the waterway style).

Other Shaft Styles: Drive arrangements are standardized to suit most common grinding machines:

  • Wing (shoulder) drive with one ‘O’ ring
  • Ausroc
  • Atlas Copco Terroc 55
  • Sandvik Sancone A
  • Plain Shaft (regular or straight)
  • Hex Socket Connection

Waterways: Pilot offers 5 distinct waterway configurations:

    • Standard Single
    • Three-Single
    • Two-Split
    • Three-Split
    • Twin-Turbo

    Single Waterway

    Standard Single

    • Available in all shaft configurations
    • Available in all crown profiles
    • Crown Profile Sizes 6MM to 13MM
    Three Waterway

    Three-Single

    • Available in all shaft configurations
    • Available in all crown profiles
    • Crown Profile Sizes 14MM to 25MM
    • Provides better flushing to the larger sizes
    • Helps to eliminates the “nipple effect” which if not corrected can result in cracking of the button due to severe concentrated loads when placed back in service

    Twin Waterway

    Twin Turbo

    • Available in all shaft configurations
    • Available in all crown profiles
    • Crown Profile Sizes 14MM to 25MM
    • Helps to eliminates the “nipple effect” which if not corrected can result in cracking of the button due to severe concentrated loads when placed back in service

    Crown Profiles

    All profiles are the combination type, where the button and surrounding steel body are cut simultaneously to provide the most effective refurbishment of the bit in a single step.
