Metric Close Space Punch Blanks with XAN DayTAN™ Coating

Q: Which shank diameter options (D) are available for this metric close-space punch blank series?

This series provides D (Shank dia.) in metric options: 02, 03, 04, 05, 06, 07 mm . Select the diameter that matches your punch holder bore and alignment requirements for stable guidance in the press.

Q: What length range (L) can I choose, and how should I set it for my tool stack-up?

The available L (Length) range is 40 ～ 100 mm . Use your punch holder/stripper stack-up to set the required protrusion and ensure safe engagement without bottoming in the guide or holder.

Q: Is a specific steel grade or hardness (HRC) provided for series 250301827447?

The input data for series 250301827447 does not specify a steel grade, hardness (HRC), or heat-treatment state (e.g., quenched & tempered or nitrided). For confirmed hardness and toughness trade-offs, you’ll need the associated material/heat-treatment documentation for this series.

Q: Can I use this blank for high-cycle press punching where die space is limited?

Yes—this variant is described as suitable for press tooling requiring reliable punching accuracy in limited die space . The close-space punch blank geometry supports compact die layouts, and the XAN DayTAN™ coating is selected to improve wear resistance during repetitive operations.

Metric Close Space Punch Blanks with XAN DayTAN™ coating are designed for precision punch fabrication where die space is limited, helping deliver consistent blanking results with stable tool performance.

Product Guide

🏭Application Scenarios+

Metric close-space punch blanks are used to build punches for applications where the punch must fit in very limited die space while still producing clean, controlled cut edges. In automotive connector and terminal press tooling, these blanks support compact die layouts and consistent blanking behavior, helping reduce edge deformation during high-cycle production.

Tight-tolerance connector slotting: close-space blank geometry supports tight die layouts for clean forming.
High-wear punching operations: the XAN DayTAN™ coating helps improve wear resistance to support longer run times and more stable tool performance.
General press punching: metric shank diameters (02–07 mm) and available lengths (40–100 mm) make it practical for punch assembly configurations.

Choose this variant when die clearance is minimal and you need durable punch blanks that maintain punching accuracy and tool stability across repeated cycles.

🔧Material & Process Details+

The provided specifications for this series focus on shank diameter D = 02–07 mm and length L = 40–100 mm, while the distinguishing technical feature is the XAN DayTAN™ coating on the punch blank.

XAN DayTAN™ coating: engineered to enhance wear resistance, supporting longer run times in abrasive or repetitive punching conditions.
Heat treatment: no steel grade or heat-treatment state (e.g., quenched & tempered, nitrided) is specified in the input data, so the exact hardness (HRC) and toughness trade-offs cannot be confirmed.
Manufacturing process relevance: the coating is applied to the blank to improve surface durability during forming, reducing the need for frequent punch replacement in tight die setups.

For hardness (HRC) or specific alloy comparisons, request the associated material/heat-treatment data sheet for series 250301827447.

📐Sizing & Selection Guide+

Select the correct blank size by matching the shank diameter D and length L to your punch holder, guide, and stripper stack-up. This series offers D = 2, 3, 4, 5, 6, or 7 mm and L = 40 to 100 mm, enabling builds for compact press tooling.

Match shank diameter: choose the closest available D (02–07 mm) compatible with your punch holder bore and alignment features.
Match punch working length: set L within 40–100 mm to achieve the required protrusion while maintaining safe engagement and avoiding guide bottoming.
Tolerance/fit considerations: since no tolerance values are provided, verify your press’s punch holder and guide clearance requirements against your internal spec before finalizing the build.
Configurable vs fixed: the geometry is configurable via the chosen D and L variants; the XAN DayTAN™ coating is the fixed series feature.

When die space is constrained, prioritize the close-space blank geometry and confirm that your stack-up leaves sufficient clearance for stable cutting.

Frequently Asked Questions

Which shank diameter options (D) are available for this metric close-space punch blank series?+

This series provides D (Shank dia.) in metric options: 02, 03, 04, 05, 06, 07 mm. Select the diameter that matches your punch holder bore and alignment requirements for stable guidance in the press.

What length range (L) can I choose, and how should I set it for my tool stack-up?+

The available L (Length) range is 40 ～ 100 mm. Use your punch holder/stripper stack-up to set the required protrusion and ensure safe engagement without bottoming in the guide or holder.

How does the XAN DayTAN™ coating benefit punching in tight die spaces?+

In tight die layouts, the punch experiences repeated contact and sliding wear under high tool duty. The XAN DayTAN™ coating is intended to improve wear resistance, helping maintain more stable punch performance over longer run times.

Is a specific steel grade or hardness (HRC) provided for series 250301827447?+

The input data for series 250301827447 does not specify a steel grade, hardness (HRC), or heat-treatment state (e.g., quenched & tempered or nitrided).

For confirmed hardness and toughness trade-offs, you’ll need the associated material/heat-treatment documentation for this series.

Can I use this blank for high-cycle press punching where die space is limited?+

Yes—this variant is described as suitable for press tooling requiring reliable punching accuracy in limited die space. The close-space punch blank geometry supports compact die layouts, and the XAN DayTAN™ coating is selected to improve wear resistance during repetitive operations.
