CNC Router Retention Knobs

DIN 69718A & B Retention Knobs

CNC Pull STuds

Features:

  • All mating surfaces precision ground
  • Manufactured to the highest standards
    for maximum safety and long life
  • Hardened for maximum longevity

Our pull studs are manufactured with the best steel that ensures minimum wear and guarantees a tough inner core that resists the normal wear and tear caused by a CNC machine.

Please make sure that the Retention Knob you order is the correct one for your machine. Using the wrong Retention Knob can cause damage to your machine spindle, the tool holder, and may cause a safety hazard.
