Operating Instructions

Transfer punches are used to mark the center of an existing hole onto another workpiece, ensuring precise alignment for drilling or machining operations.

1. Select the Correct Size: Choose a transfer punch that matches the diameter of the existing hole you wish to transfer. The punch should fit snugly into the hole without excessive play.
2. Align Workpieces: Position the workpiece with the existing hole directly over the target workpiece where the mark needs to be transferred. Secure both pieces to prevent movement during the marking process.
3. Insert Punch: Insert the selected transfer punch into the existing hole until its tip rests on the surface of the target workpiece.
4. Mark the Surface: Using a hammer, strike the top of the transfer punch firmly but carefully. For softer materials like wood or plastic, a single moderate strike may suffice. For harder materials such as metal, a lighter initial tap to create a pilot mark, followed by a more robust center punch, is recommended to prevent damage to the transfer punch tip and ensure a clear mark.
5. Verify Mark: Remove the punch and the top workpiece. A clear, precise mark should be visible on the target surface, indicating the exact center for subsequent drilling or machining.

Maintenance

• Cleaning: After each use, wipe down the punches with a clean, dry cloth to remove any debris or residue.
• Rust Prevention: The punches feature a black oxide finish for rust and corrosion protection. For prolonged storage, especially in humid environments or unheated garages, applying a light coat of rust-preventative oil (such as WD-40) is recommended.
• Storage: Always store the punches in their provided index stand to prevent damage to the tips and maintain organization. Store in a dry place.
• Inspection: Periodically inspect the punch tips for wear or damage. While designed for durability, excessive force or improper use can dull or deform the tips.

Troubleshooting

• Punch Not Marking Clearly:
  • Ensure the punch tip is clean and free of debris.
  • Verify the punch size matches the existing hole for proper contact.
  • Increase the force of the hammer strike, or use a center punch for harder materials after an initial light mark with the transfer punch.
• Punch Tip Damage (Bending/Dulling):
  • Avoid hitting the punches too hard, especially on very hard materials.
  • Ensure the punch is held perpendicular to the workpiece to distribute force evenly.
  • Consider using a dedicated center punch for initial marking on tough surfaces to preserve the transfer punch tips.
• Punches Sticking in Stand:
  • Ensure punches are clean and dry before storing.
  • A light application of lubricant to the body of the punches can help if they are difficult to remove.
