Select the Correct Punch: Ensure you are using the 8mm Mayhew Pilot Pin Punch for 8mm metric roll pins. Using the wrong size can damage the pin or the workpiece.
Position the Workpiece: Secure the item containing the roll pin in a vise or on a stable surface to prevent movement during the punching process.
Align the Punch: Place the rounded tip of the punch directly into the hollow opening of the roll pin. For driving a pin in, align it with the hole. For removal, ensure the pin is accessible from one side.
Strike the Punch: Using a hammer (preferably a brass or soft-faced hammer to prevent damage to the punch or pin), strike the end of the punch firmly and squarely. Apply controlled force, especially when removing stubborn pins.
Monitor Progress: Observe the pin's movement. For insertion, stop once the pin is flush or seated as desired. For removal, continue striking until the pin is fully expelled from the hole.
Clean Up: Once the task is complete, clean any debris and safely store the punch.
