Manufactured from M2 grade high-speed steel and heat-treated to a hardness of 60-63 HRC, this punch delivers consistent performance under high-impact cyclic loading. The ball lock retention system provides positive, repeatable seating in the punch holder without the need for set screws. With a 1.23-inch shank diameter and an overall length of 4.75 inches, this blank punch is sized for standard die set configurations used by toolmakers and die maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis blank punch is designed for use in metal stamping dies, progressive dies, and mold and die fabrication environments. The Jektole (HJB) series is a recognized standard in the tool and die industry, commonly found in both production stamping shops and precision tool rooms. The unfinished blank profile allows machinists to grind the working end to a custom profile suited to the specific die application. Typical installers include tool and die makers, punch press maintenance technicians, and precision machining shops working with ferrous and non-ferrous sheet materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 grade high-speed steel construction for excellent wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eHardness rated at 60-63 HRC for extended service life under impact loading\u003c\/li\u003e\n  \u003cli\u003eBall lock design ensures positive, repeatable punch retention in compatible holders\u003c\/li\u003e\n  \u003cli\u003eSolid blank profile  -  machinable to custom working-end geometry\u003c\/li\u003e\n  \u003cli\u003eMinimum machinable length of 0.5 inches with a pin extension length of 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003eJektole (HJB) series  -  a widely adopted standard in production die sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in die sets and punch holders that accept ball lock style punches with a 1.23-inch shank diameter, consistent with the Jektole (HJB) series standard.

Ensure the press is locked out and all energy sources are isolated before removing or installing punches. Confirm the punch holder bore and ball lock pocket are clean and free of debris before seating the punch. Do not modify the shank diameter or ball lock geometry; machine only the working end to the required profile.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.75 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: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162807\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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 62 475 M2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51996090925362,"sku":"HJB 62 475 M2","price":103.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022db6a99734ab31d2a4e8c43e036490_8363c2d5-be40-4878-914b-350ff506b583.jpg?v=1789993153","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-hjb-62-475-m2-solid-mold-die-blank-punch","provider":"Voomi Supply","version":"1.0","type":"link"}
