Application Selection
Start with the perforation, sheet material, and required Type A geometry.
The #572 should be selected from the component print and press-tool requirement rather than from series number alone.
02
Confirm the punch dimensions
The catalog ordering line identifies d1, d2, T, l1 and l2 as the dimensions to specify.
03
Select material & finish
Choose between the catalog-listed HSS and ASP30 options based on the application, and identify any coating or special finish requirement during quotation.

Manufacturing note: use the current Universal Punch controlled drawing and RFQ review to confirm final dimensions, tolerances and surface requirements before manufacture.
Material Selection
HSS and ASP30 are the catalog-listed options.
Material selection should follow work material, wear conditions, production volume, tool geometry, and current Universal Punch manufacturing guidance.
High Speed Steel
The catalog describes HSS for high-strength or difficult-to-work materials and notes abrasion resistance, tensile strength, and heat resistance.
- Shaft: HRC 62–64
- Head: HRC 45–55
- Special surface coating available on request per catalog note
Powder-metallurgy high-speed steel
The catalog identifies ASP30 as powder-metallurgy-manufactured high-speed steel and notes increased life expectancy in an application such as piercing stainless material.
- Shaft: HRC 65–67
- Head: HRC 48–55
- Evaluate when application wear demands justify the material choice
