Key specifications

How to use

Mark the desired hole position on the material and position the material between the punch and die. Squeeze the handles evenly until the punch fully penetrates the material and a clean 4 mm hole is produced. Release the handles to withdraw the punch and remove the scrap. For thicker or multiple layers, support the material on a firm surface and ensure the punch and die remain aligned during each operation.

Recommendations

For best results, keep the die area clear of debris and occasionally check the punch edge for wear. Use steady, even pressure rather than rapid forceful strikes. When working with very thin or highly woven textiles, consider stabilizing the area with backing material to prevent fraying. Store the pliers in a dry place to avoid corrosion and inspect before use to ensure safe operation.
