Operating Instructions

Transfer punches are used to accurately mark the center of an existing hole onto another surface, typically for drilling or machining operations.

1. Prepare Workpieces: Ensure both the master workpiece (with the existing hole) and the new workpiece (where the mark will be transferred) are clean and free of debris.
2. Align Workpieces: Position the master workpiece precisely over the new workpiece, ensuring they are correctly aligned as required for your project. Securely clamp both workpieces together to prevent any movement during the transfer process.
3. Select Punch Size: Choose a transfer punch that precisely fits the existing hole in the master workpiece. The punch should slide into the hole without excessive play but also without being too tight. The set provides a range of sizes from 3/32" to 1/2" (by 64ths) and a 17/32" punch to match various hole diameters.
4. Insert Punch: Insert the selected transfer punch into the hole of the master workpiece until its pointed tip rests on the surface of the new workpiece.
5. Marking: Using a hammer, strike the top of the transfer punch firmly and squarely. A single, sharp blow is usually sufficient to create a clear, visible center mark on the new workpiece. Avoid multiple light taps, as this can lead to inaccurate marks.
6. Verify Mark: Remove the punch and the master workpiece. Inspect the new workpiece to ensure a clear and accurate center mark has been made. This mark will serve as the guide for drilling or other machining operations.

Maintenance

• Cleaning: After each use, wipe down the punches with a clean, dry cloth to remove any debris, oil, or moisture. For stubborn grime, a mild solvent can be used, followed by thorough drying.
• Lubrication: Apply a light coat of rust-preventative oil to the punches, especially if they will be stored for an extended period or in a humid environment.
• Inspection: Regularly inspect the tips and striking ends of the punches for signs of wear, mushrooming, or chipping. Damaged punches can lead to inaccurate marks or pose a safety risk. Replace or re-grind damaged punches as necessary.
• Storage: Always store the transfer punches in their original plastic storage case. This protects them from damage, keeps them organized, and prevents rust by minimizing exposure to moisture and contaminants. Store the case in a dry, temperate location.
