Close Space Punches Metric

Close clearance punch stations in progressive die sets are where these punches deliver the most value. The fixed P dimension 0.8 mm supports reliable seating in compact tool layouts, helping minimize interference between adjacent tooling components while keeping punch alignment consistent.

• Automotive and appliance progressive dies: used for blanking and forming close features where tool blocks have limited real estate; tight spacing reduces collision risk during high-cycle operation.
• Punch-and-form operations: supports repeatable motion in die maintenance scenarios where shank fit to holders must remain stable over repeated reassembly.
• Die repair and refurbishment: metric compatibility aids replacement of standard punches in press tooling, maintaining performance without requiring significant rework to the turret layout.

These punches are suited to close-clearance stations because the 0.8 mm P dimension is optimized for maintaining clearance while still providing dependable guidance through the holder interface.

The provided specification data does not include an exact steel grade, coating chemistry details beyond the XN DayTride® option, or hardness (HRC). As a result, the material section focuses on how this product is typically manufactured and what the documented coating choice implies for performance.

• Surface protection: XN DayTride® is offered as a coating option to improve surface wear resistance for frequent punch use in abrasive or high-cycle applications.
• Heat treatment state: hardness and treatment (e.g., pre-hardened vs. quenched & tempered, nitrided) are not specified in the input data, so exact values cannot be stated.
• Trade-offs: in close-space punches, wear resistance must be balanced with toughness to avoid chipping under load and misalignment; coatings help shift this balance toward longer wear life.

When specifying for duty cycle and press tonnage, confirm the steel grade and target HRC with your Axiom Molds application engineer.

Use the listed dimensions to match the punch to the die block and guide features. The shank diameter D is variable in the set: 2, 3, 4, 5, 6, or 7 mm. The length L is fixed-range: 40 to 100 mm (select the length that provides sufficient engagement through your holder and stripper/support stack).

• Match shank diameter (D): select the D value that fits the holder’s bore/guide to avoid excessive clearance (risking misalignment) or tight interference (risking assembly binding).
• Verify effective clearance (P): the documented P dimension range is 0.8 to 6.01 mm, with the product variant described as having fixed P dimension 0.8 mm for tight spacing; confirm the required P for your adjacent tooling envelope.
• Check length (L): choose L so the working end is properly supported and full stroke loading is consistent across reassemblies.

Exact tolerance values are not provided, so finalize fit by referencing the die-maker’s holder/guide tolerances and conducting a trial fit for first article validation.
