Metric Straight Regular Punches XNT DayTiN® Coating

Q: Which fixed dimensions define compatibility with my die cavity/core stack for this straight punch series?

This series provides fixed selection ranges of L (Length) = 50–100 mm and P Dimension = 3–16 mm . L should be chosen to match your die stack height and required engagement, while P must match the working size needed for the hole-forming operation. The input data does not include tolerances, so confirm clearance requirements using your progressive die tolerance stack.

Metric Straight Regular Punches with XNT DayTiN® coating from Dayton are designed for stable, long-cycle punching in progressive tooling. The TiN-based surface helps reduce wear and maintain dimensional consistency under production loads.

Product Guide

🏭Application Scenarios+

These metric straight regular punches are used as driven cutting elements in progressive die sets, where the punch repeatedly forms clean, stable through-holes with minimal dimensional drift. The XNT DayTiN® surface coating is especially suited for high-cycle production because it helps resist abrasive wear at the cutting edge and maintains consistent punching performance.

Automotive and appliance progressive tooling: Use for long production runs that demand predictable hole geometry while the press cycles rapidly. The TiN-based coating supports efficient press life under steel punch-through conditions.
Terminal and connector blanking: Suitable when repeated straight punching must keep hole position and finish stable across multiple stations. The metric format simplifies integration with standardized die and holder build-ups.
General industrial perforation: Works well for tool rooms and production lines producing parts that rely on reliable straight shearing and consistent part-to-part dimensional repeatability.

🔧Material & Process Details+

The key differentiator for this punch series is the XNT DayTiN® coating, a TiN-based surface treatment intended to increase abrasion and wear resistance at the punch working face. This improves edge durability during repetitive shearing in progressive dies.

Coating function: Reduces metal-to-metal wear and helps maintain cutting performance over many cycles.
Heat treatment: The input data does not specify the punch substrate steel grade or heat-treatment state (e.g., quenched & tempered, nitrided). Therefore, hardness (HRC) and toughness trade-offs between substrate grades cannot be stated from the provided specifications.
Comparing coatings: If selecting between uncoated punches and TiN-based coated options, the coated variant is typically chosen for higher wear environments where edge life is critical. For precise HRC targets, the substrate grade must be confirmed.

📐Sizing & Selection Guide+

To select the correct punch, match the required punching geometry to the provided fixed dimensions. This series is available with L (Length) = 50–100 mm and P Dimension = 3–16 mm, where both values are fixed for ordering.

Select length (L): Choose a length that supports proper protrusion and engagement through your die stack while leaving sufficient material for alignment and wear compensation. Use the total die build-up height of your progressive station to determine the needed working reach.
Select punch size (P): Use the required straight punch working dimension for the hole shearing operation; ensure it aligns with the mating die opening in your progressive die design.
Tolerance & fit: The provided data does not list tolerance grades. Plan for standard punch-and-die clearance practices in progressive tooling and verify final fit against your die maker’s tolerance stack-up.

If you require dimensions outside these ranges, confirm availability in adjacent series codes rather than substituting dimensions.

Frequently Asked Questions

For progressive dies, how does the XNT DayTiN® coating affect punch wear compared with uncoated straight punches?+

The XNT DayTiN® coating is TiN-based and is intended to improve abrasion and wear resistance at the punch working surface. In progressive tooling, that helps reduce edge degradation over repeated shearing cycles. For exact life gains, you should validate with your material and press speed, since the provided data does not include wear-life test metrics.

Which fixed dimensions define compatibility with my die cavity/core stack for this straight punch series?+

This series provides fixed selection ranges of L (Length) = 50–100 mm and P Dimension = 3–16 mm. L should be chosen to match your die stack height and required engagement, while P must match the working size needed for the hole-forming operation. The input data does not include tolerances, so confirm clearance requirements using your progressive die tolerance stack.

Can I use this punch for multi-station hole punching where positional stability is critical?+

Yes—this punch is designed for stable, long-cycle straight punching in progressive tooling, where consistent hole formation matters across stations. The TiN-based coating supports maintaining punching performance under production loads. Final positional stability still depends on die alignment and your press setup, which are not covered in the provided specs.

What substrate hardness (HRC) or heat-treatment state is specified for this punch series?+

The provided specifications do not list the steel grade, quench-and-temper state, nitriding, or any HRC hardness value for the punch substrate. Because the substrate details are missing, hardness and toughness trade-offs cannot be verified from the given data. Request the substrate material and heat-treatment datasheet for HRC confirmation.
