Metric Close Space Straight Punches XNT DayTiN® Coating

Close-space straight ejection in tight die cavities is where these punches provide the most benefit—especially when straight, stable motion is required without excessive clearance.

• Automotive and forming die tooling: Use the metric close-space straight punch style to eject or drive blanks through narrow die openings. The close-space geometry helps maintain alignment, while the XNT DayTiN® coating improves wear resistance under repetitive high-cycle punching.
• Industrial sheet metal punching: In compound or progressive die sets, the punch’s straight engagement supports consistent part removal when multiple stations run back-to-back. The coating variant is suited for maintaining surface durability against friction and sliding contact.
• Metric die sets for production fixtures: When standardization and easy matching to existing Dayton/Lamina tool components matter, this punched-format supports streamlined procurement and replacement for metric tooling environments.

Select the regular head or angled head (AWX) variant based on how the punch interfaces with your holder and clearance constraints.

The product variant provided specifies the punch format and the XNT DayTiN® coating for improved surface durability in die-and-punch applications. While the exact steel grade and base hardness are not included in the provided data, the functional intent of DayTiN® is to increase wear resistance at the punch working surface and help resist degradation during repetitive forming cycles.

• Wear vs. toughness trade-off: Hard, wear-oriented coatings typically prioritize abrasion resistance; however, adequate punch base toughness is still required to prevent chipping under impact loads.
• Manufacturing process: The punch is produced to the specified close-space geometry, then coated with XNT DayTiN® to enhance the friction and wear performance of the working face.
• Heat treatment state: Not specified in the supplied parameters; consult the specific steel/heat-treatment documentation tied to the series code if base hardness (HRC) or treatment (e.g., quenched & tempered, nitrided) is needed for design sign-off.

Correct selection is based on matching the punch’s length (L) and the P dimension (0.8 to 7 mm) to your die spacing and punch-holder stack-up. Use the metric format to ensure compatibility with your metric die set geometry.

• Length (L): Choose from 40 ～ 100 mm to reach the required working engagement depth in your tooling. Confirm that the chosen L provides sufficient protrusion while maintaining safe clearance to stop surfaces.
• P dimension: Select P in the 0.8 ～ 7 mm range to fit the close-space working interface of your die. This dimension strongly affects the contact area and guidance in confined tooling.
• Geometry/type: Ensure you select the correct head style—Angled head (AWX) or Regular head (AXX)—to match your holder and clearance.

If you require specific working tolerances for your die cavity/core matching, verify tolerance values from the datasheet tied to the series code; they are not included in the provided parameter list.
