Regular Punch Blanks for Heavy Load - Metric

These heavy-load punch blanks are used as intermediate tooling components when building progressive and single-station punching setups for sheet metal forming. Their metric shank range of 8–25 mm and selectable lengths (50–100 mm, or 60–100 mm depending on the option) help you match the required stick-out and press alignment for stable punching.

Automotive and industrial brackets: In high-cycle operations, the blank format supports rigid punch holders and consistent energy transfer, reducing setup variability across runs.

Appliance and enclosure stampings: For forming steps that require repeatable penetration and tool longevity, choose the variant with the shank diameter that fits your existing punch retainer or guide system in the Dayton/Lamina numbering ecosystem.

Manufacturing cells with standardized part numbering: Because this blank is offered for the Dayton and Lamina part-number format, procurement and cross-referencing are faster when maintaining legacy tooling or building new tools to existing standards.

• Metric diameters ensure compatibility with metric tooling stack-ups
• Length options support varying tool heights and press clearances

The provided product data specifies tooling geometry (shank diameter D: 08–25 mm, length L: 50–100 mm / 60–100 mm) but does not include a steel grade, heat treatment condition, or hardness target. Therefore, material properties such as HRC, wear resistance, and toughness trade-offs cannot be stated from the supplied information.

In punch blank applications, engineers typically select a steel grade and heat treatment based on expected tonnage, abrasive wear, and impact/loading during punching. Common approaches in heavy-load punch tooling include hardened and tempered tool steels or surface-strengthened options (e.g., nitriding) to improve wear while managing toughness.

• Verify steel grade and heat treatment documentation for hardness (HRC) before final tool design
• If multiple material grades are offered for the same geometry, compare wear resistance vs. toughness for your press cycle profile

Start by matching the blank’s shank diameter D to your existing punch holder/retainer and guide system. Select from the available metric options: D = 08, 10, 13, 16, 20, or 25 mm.

Next, choose the correct length L to achieve the required stick-out and maintain alignment through the press. The available ranges are L = 50–100 mm or L = 60–100 mm (depending on the specific variant/order configuration).

• Match D to the cavity/core-side guidance requirements of your punching station (avoid forcing fit)
• Set L to ensure the punch seats properly without bottoming out in the holder
• Maintain press alignment to prevent bending under heavy-load punching

Tolerance and fit: no tolerance values are provided in the input data, so rely on your punch holder bore/guide tolerance and perform a dimensional check on receipt. For best compatibility with standardized stacks, keep the selected geometry consistent with the Dayton/Lamina part numbering you are cross-referencing.
