DAYTON Close Space Straight Punches - Inch, XNT DayTiN® Coating

Q: How do I choose between the Regular head (KCX) and Angled head (KWX) versions for tight die clearance?

Use the KCX regular head when your setup provides straight access to the forming zone and guide alignment is straightforward. Choose KWX angled head when strip-feed direction, die access, or guide geometry requires a non-straight approach to maintain proper alignment during the press cycle.

Q: What size ranges are available for the inch close-space straight punch in this series?

The series supports L (Length) = 150 to 400 in and P dimension = 0.04 to 0.25 in . Select L based on press stroke space and the need for rigidity, then confirm P against your close-space clearance requirements on the die drawing.

Q: Why is the XNT DayTiN® coating specified for close-space punching and trimming operations?

The listing specifies XNT DayTiN® coating to improve wear resistance and tool service life under repetitive punching/trimming loads. In tight die areas, maintaining consistent tool geometry helps control wear-related dimensional drift and helps keep forming results clean.

Q: Can I confirm the substrate steel grade and HRC from the provided data?

No. The current input only confirms the XNT DayTiN® coating and the geometric specifications ( L and P ), but it does not provide the base steel grade or hardness (HRC) values. To select by hardness requirements, request the substrate material and heat-treatment documentation for this series.

Q: How should I account for tolerance and side-loading when matching P dimension (0.04–0.25 in) to my die design?

Because P is within 0.04 to 0.25 in , it is likely clearance-sensitive for close-space operation. Validate tolerances on your die plate spacing, guides, and alignment features, and ensure the punch profile can run with minimal side loading to reduce edge wear and risk of chipping.

Close Space Straight Punches - Inch (DAYTON) (XNT DayTiN® coating) are designed for forming operations where working space is limited. The straight punch geometry supports efficient load transfer and stable alignment during each press cycle.

Product Guide

🏭Application Scenarios+

Close-space straight punches are used when the punch must operate in limited working clearance, such as in compact progressive and trimming die sets. Their straight punch geometry helps maintain stable alignment and efficient load transfer through the press cycle, which is critical for consistent hole formation and edge quality.

In automotive-grade bracket and connector production, these punches are commonly applied to secondary operations like in-die punching and trimming where die space is constrained. The XNT DayTiN® coating supports extended wear life, reducing dimensional drift and improving repeatability over longer production runs.

For appliance and consumer hardware stamping, select the angled head (KWX) option to match access and strip-feed conditions, or use the regular head (KCX) configuration when straight access is available. Matching the head style to your tool setup helps minimize misalignment risk and supports clean forming in tight die areas.

🔧Material & Process Details+

The provided specifications identify an XNT DayTiN® coating variant for these inch close-space punches. This surface treatment is selected to enhance wear resistance and improve tool service life during repetitive punching and trimming.

Because no base steel grade or hardness (HRC) values are included in the input data, the heat-treatment state (e.g., quenched & tempered, nitrided) and exact hardness cannot be confirmed from the current listing. In practice, coatings like DayTiN are typically applied to a hardened punch substrate to balance toughness (resisting chipping) and abrasion wear resistance (resisting edge degradation).

XNT DayTiN® coating: targets longer life under sliding/abrasive wear in production forming
Trade-off: maximizing wear protection must be paired with a sufficiently tough substrate to prevent chipping under cyclic impact
Material comparison: no alternate steel grades are specified here, so only the coating-based differentiation is confirmed

📐Sizing & Selection Guide+

To select the correct punch length and clearance-critical dimensions, start by matching the available stroke space and die layout in your tooling design. This series is available with Length L = 150 to 400 in, and you should choose the shortest length that safely engages the strip and maintains rigidity within the press frame.

The listing also specifies P dimension = 0.04 to 0.25 in. Use your die drawing to determine the required value of P based on the close-space clearance and intended engagement depth—select a punch with P that fits your cavity/core proximity without causing interference.

Match to cavity/core clearance: confirm that the close-space straight profile can operate within the limited die clearance while keeping punch alignment stable
Fit and tolerance: treat P as a clearance-sensitive dimension—verify tolerances in your die plate fit-up and guide system to reduce side loading
Configurable options: choose Regular head (KCX) or Angled head (KWX) to suit access and alignment constraints
