Built from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, providing excellent wear resistance under high-cycle conditions. The ball lock retention system ensures secure seating in the die set without the need for additional fasteners. With a 4.5-inch overall length and a 1.25-inch shank diameter, this punch is sized for demanding production tooling environments. Tool and die makers, machining shops, and stamping operations rely on components like this for repeatable, high-tolerance performance.\u003c\/p\u003e\u003cp\u003eThis blank punch is designed for use in solid mold die sets where the working end requires custom machining to a specific profile. The Jektole (HJB) series configuration makes it well suited for progressive die, stamping, and forming tooling. The blank profile allows in-house grinding or EDM to the required punch geometry, giving toolmakers flexibility across a wide range of part profiles. Typical applications include metal stamping dies in both light and heavy manufacturing environments where M2 high-speed steel is the specified material grade.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 grade high-speed steel construction with 60-63 HRC hardness for extended tool life\u003c\/li\u003e\n\u003cli\u003eBall lock shank design for positive retention and quick changeover\u003c\/li\u003e\n\u003cli\u003eBlank (unground) tip allows custom machining to required punch profile\u003c\/li\u003e\n\u003cli\u003eJektole (HJB) series configuration for compatibility with standard HJB die set systems\u003c\/li\u003e\n\u003cli\u003e4.5-inch overall length with 1.25-inch shank diameter for use in production tooling\u003c\/li\u003e\n\u003cli\u003eMinimum machinable length of 0.5 inches with 0.0625-inch pin extension length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for die sets accepting the Jektole (HJB) series ball lock blank punch with a 1.25-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of die punches should be performed by qualified tool and die makers or machine shop personnel with experience in die set assembly. Ensure the press is fully locked out and de-energized before removing or installing any die components. The blank punch tip must be precision ground or EDM-machined to the required profile before production use. Verify ball lock seating and retention before cycling the press.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jektole (HJB)\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\u003eHardness\u003c\/strong\u003e: 60-63 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.5 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\u003eRetention Type\u003c\/strong\u003e: Ball Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePunch Type\u003c\/strong\u003e: Solid Blank\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 125 450 M2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51971273359666,"sku":"HJB 125 450 M2","price":242.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022db6a99734ab31d2a4e8c43e036490_3d388918-53c3-4384-8374-7e1b2fed2acd.jpg?v=1789955277","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-hjb-125-450-m2-solid-mold-die-blank-punch","provider":"Voomi Supply","version":"1.0","type":"link"}
