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.
