Built from M2 grade high-speed steel and hardened to 60-63 HRC, this punch delivers consistent performance under high-cycle conditions. The ball lock retention system provides secure seating in the die set, reducing the risk of punch migration during press operation. With a 7\/8 inch shank diameter and a minimum machinable length of 0.5 inches, this blank punch ships ready for custom grinding to final profile. Weighing 0.375 pounds, it is part of the Jektole (HJB) Series from Dayton Lamina.\u003c\/p\u003e\u003cp\u003eThis blank punch is suited for use in progressive dies, compound dies, and mold tooling setups across metal fabrication and stamping shops. It is used in applications where a standard off-the-shelf punch profile is not available and the toolmaker requires a solid, pre-hardened blank that can be machined to a custom geometry. The Jektole (HJB) Series is a recognized line in production tooling environments where high-volume, tight-tolerance punching is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 grade high-speed steel construction for heat and wear resistance under continuous press cycles\u003c\/li\u003e\n\u003cli\u003eHardness rated at 60-63 HRC for reliable cutting edge retention\u003c\/li\u003e\n\u003cli\u003eBall lock design for positive punch retention in the stripper or holder\u003c\/li\u003e\n\u003cli\u003e7\/8 inch shank diameter with 1.0000 inch shank diameter per spec attributes\u003c\/li\u003e\n\u003cli\u003eMinimum machinable length of 0.5 inches allows custom profile grinding\u003c\/li\u003e\n\u003cli\u003ePin extension length of 0.0625 inches for precise ball lock engagement\u003c\/li\u003e\n\u003cli\u003ePart of the Jektole (HJB) Series, a standard tooling platform in production stamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style blank punch replacement for use in die sets and stamping tooling assemblies that accept ball lock style punches with a standard shank configuration in the Jektole (HJB) Series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified toolmaker or die maintenance technician. Ensure the press is fully de-energized and locked out before removing or installing any punch components. Ball lock punches require proper alignment with the mating retainer or holder bore to seat correctly. Custom profiling should be performed prior to final installation; consult applicable tooling drawings and machine tolerances before grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Machinable Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Extension Length\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60-63 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jektole (HJB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.375 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162807\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DAYTON LAMINA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HJB 87 425 M2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51965431284018,"sku":"HJB 87 425 M2","price":148.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022db6a99734ab31d2a4e8c43e036490_02539bf2-5913-4743-9b9c-bfc805decb97.jpg?v=1789949764","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-hjb-87-425-m2-solid-mold-die-blank-punch","provider":"Voomi Supply","version":"1.0","type":"link"}
