Built from M2 grade high-speed steel, it delivers consistent performance under high-cycle punch press conditions. The shank diameter measures 0.2030 inches, with a pin extension length of 0.0625 inches and a minimum machinable length of 0.5 inches. The overall length (OAL) is 4.25 inches. Hardness is rated at 60-63 HRC, making it suitable for demanding production environments. The ball lock retention system provides quick, repeatable seating in the die set without additional fasteners.\u003c\/p\u003e\u003cp\u003eThis blank punch is used in metal stamping dies, mold tooling, and progressive die assemblies. It is well suited for applications where a solid, unformed punch face is required prior to custom grinding or profiling by the tool and die maker. The Jektole (HJB) series is a recognized standard in industrial punch tooling, commonly specified in manufacturing, fabrication, and toolroom environments where interchangeability and consistent dimensional tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 grade high-speed steel construction for extended tool life in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eHardness of 60-63 HRC for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eBall lock shank design for secure, tool-free retention in the die holder\u003c\/li\u003e\n\u003cli\u003eShank diameter of 0.2030 inches with pin extension length of 0.0625 inches\u003c\/li\u003e\n\u003cli\u003eSolid blank face for custom profiling by the end user\u003c\/li\u003e\n\u003cli\u003ePart of the Jektole (HJB) series for standardized tooling interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in die sets and punch holders configured for the Jektole (HJB) series ball lock punch standard.

Ensure the press and die set are fully de-energized and locked out before handling or replacing punch components. Confirm that the holder bore is clean and free of debris before seating the punch to maintain alignment tolerances. Custom grinding of the blank face should be completed before mounting in a production die set.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.25 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\u003eRetention Type\u003c\/strong\u003e: Ball Lock\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: 0.5 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 125 425 M2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51969614119218,"sku":"HJB 125 425 M2","price":241.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022db6a99734ab31d2a4e8c43e036490_c636ae0b-fda1-4f4a-8fae-be12c61efec7.jpg?v=1789952432","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-hjb-125-425-m2-solid-mold-die-blank-punch","provider":"Voomi Supply","version":"1.0","type":"link"}
