Close Space Punch Blanks Metric XN DayTride Coating

Close-space punch blanks are used as precision punch tooling components inside injection and press-related forming areas where the designer must maintain very tight die clearances. They help establish stable punching geometry in compact tooling layouts, reducing misalignment risk during high repetition cycles.

• Automotive connector and bracket housings: When producing trim features or local holes in reinforced parts, the close-space blank format supports consistent punching in tight die layouts.
• Consumer electronics enclosures: For small-format stamped or formed features, the metric shank diameters (D = 2–7 mm) enable tooling builds that match miniature cavity/core constraints.
• Appliance and general industrial brackets: The DAYTON XN DayTride® coating improves wear resistance under cycle loads, supporting repeatable performance as press duty increases.

This specific variant is suited for these scenarios because it combines a close-space design with a wear-focused coating, helping maintain punch dimensional stability over long production runs.

The provided specifications describe dimensional variants and the DAYTON XN DayTride® coating, but they do not include the underlying steel grade or measured hardness (HRC). For material selection and reporting to your shop, confirm the supplied datasheet for the exact substrate steel and heat treatment state (e.g., quenched & tempered vs. nitrided).

From an engineering standpoint, the key functional role of the XN DayTride® coating is surface wear resistance, which helps reduce tool wear and supports stable punching under repeated cycle loads. Coatings typically trade off extreme toughness for improved abrasion resistance; therefore, ensure your punch loading, alignment, and die clearance strategy are consistent with the intended close-space use case.

• Coated variant: optimized for lower wear rates and smoother punching behavior.
• Uncoated variant (if applicable in your procurement): may offer different friction/wear performance, but this product is specifically specified with XN DayTride® for repeatability.

Correct selection starts with matching the punch shank diameter D and the working/tool length L to your tool support and the cavity/core envelope in the die set.

• Select shank diameter (D): choose from the available metric sizes D = 02, 03, 04, 05, 06, 07 mm. This should match the die guide bore/support and alignment requirement for your press.
• Select length (L): pick within the fixed range L = 40 to 100 mm to suit your press stroke and how much protrusion is required for the punch operation.

To minimize deflection in close-clearance layouts, use the smallest practical shank diameter that still ensures stable guidance. If your tooling drawings specify fits or guide clearance, align the selected D with your guide bore tolerances and consider any stack-up from die plates. Since L is fixed to discrete values within 40–100 mm (per available catalog offerings), confirm the final required protrusion against your press setup before ordering.
