Close Space Straight Punches - Inch XN DayTride Coating

Close clearance straight punches are used in die sets where tooling must maintain precise punch guidance within limited space between the punch and surrounding die components. This variant is suited for high-cycle die work because the surface is protected with XN DayTride®, helping reduce adhesive and sliding wear during repeated stamping.

• Automotive and appliance bracket blanking: stable straight guidance improves part-to-part dimensional repeatability when the die cavity has tight clearance and multiple stations.
• Electronics and connector housings (metal inserts): the punch style supports clean material shearing where alignment is critical to avoid burr growth.
• General fabrication with close-quarters tool layouts: the fixed length range and small P dimension support integration into compact die structures.

Choose the regular head (KCX) or angled head (KWX) based on your tool layout to maintain alignment with the die’s working direction.

Product literature provided specifies the use of an XN DayTride® coating, but does not state the underlying punch steel grade or an explicit heat-treatment condition (e.g., quench-and-temper, nitriding) in the supplied data. For material selection, engineers should treat the coating as the primary differentiator for wear performance in close-clearance punching.

• XN DayTride® coating: designed to improve surface durability under sliding contact and repetitive punch-and-die cycles.
• Wear vs. toughness trade-off: coatings generally improve abrasion/adhesion resistance at the contact surface, while bulk toughness is governed by the underlying steel and heat treatment (not specified here).

If you require a specific steel grade (for example, for impact-heavy applications), confirm the base material and hardness through the product’s technical data sheet before finalizing your die design.

Selection is driven by the fixed size ranges in your die drawing and the available clearance in the tool assembly. This close-space straight punch series provides L (Length) = 150 to 400 in and a P dimension = 0.04 to 0.25 in, so match these values to your stripper/support stack-up and die height requirements.

• Match L to die stack-up: ensure the punch working engagement and retention length accommodate guide length and holder design without bottoming.
• Match P to clearance/interface geometry: set P to maintain the intended close clearance in the die space so guidance remains stable during cycling.
• Head geometry selection: use KCX (Regular head) for standard alignment or KWX (Angled head) when your tool layout requires an offset head profile.

Because the tolerance values are not provided, validate dimensional tolerances against your press and die clearing requirements in the manufacturing drawing package.
