Precision and reliability are essential in metalworking, and having the right punch and die tooling can make all the difference. Our Punch & Dies Selection & Troubleshooting Guide provides essential guidance on selecting and maintaining punch and die tooling, ensuring top performance and helping to resolve common issues.
Whats Inside:
The Punch & Die Range
We offer an extensive range of punches and dies available for next-day delivery. This selection includes all standard rounds, squares, and popular slot sizes for major brands Geka, Kingsland, and Morgan Rushworth machines, as well as others such as Promtech, IMAC, Selfer and Alfra. Key benefits include:
- High Manufacturing Standards: All tooling is produced in the UK from hardened steel, ensuring durability and reliability.
- Efficient Scrap Management: Punching is ideal for low to medium volume work, producing manageable scrap instead of swarf piles, which suits workshops aiming for precision with minimal waste.
Specialist Tooling Options
In addition to standard tooling, Selmach provides specialised punches and dies for unique applications, such as notching vent holes for galvanising, radius corner tools, and countersinking punches. Custom tooling is available to meet specific needs, supporting a wide range of metalworking tasks.

Punch and Die Dimensions
The guide includes detailed specifications for various machine models, covering standard sizes and dimensions for both punches and dies. This information helps ensure you select the right tooling for your machine’s tonnage and operational requirements.
Troubleshooting Common Issues
The guide addresses several common problems encountered when using punch and die systems and provides clear solutions:
- Stripping Failure: If there’s too much stripper clearance, adjust the stripper closer to the material for optimal contact.
- Heavy Galling: Caused by misalignment between punch and die, leading to drag. Realigning punch and die can prevent galling and prolong tooling life.
- Punch Head Failure: Often due to a loose coupling nut or punch stem. Regularly check and tighten the coupling nut to avoid this issue.
Additional Tips for Quality and Efficiency
For consistent punch quality and reduced deformation:
- Adjust the Clamping System to stabilise material during punching.
- Set Stroke Limit Switches accurately to control punch depth and avoid over-penetration, which can damage tooling.
