Manufactured from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, making it well suited for demanding tooling applications. The ball lock retention style provides a secure, repeatable mount in compatible punch holders. With a 0.5-inch shank diameter and an overall length of 4.25 inches, this blank punch is a precision-ground tool component used by tool and die makers, press room technicians, and metalworking shops that require consistent, reliable punching performance.\u003c\/p\u003e\n\u003cp\u003eThis blank punch is used in progressive die sets and mold die assemblies found in metal stamping and fabrication environments. It is appropriate for both prototype tooling and production die work where an unground, solid blank is needed for custom machining to final form. The minimum machinable length of 0.5 inches and the 0.0625-inch pin extension length provide adequate stock for secondary grinding operations to achieve the desired punch profile. This part is suited for light-to-medium production stamping work in tool shops and manufacturing facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2 grade high-speed steel construction for wear resistance and toughness in stamping applications\u003c\/li\u003e\n  \u003cli\u003e60-63 HRC hardness rating for extended tool life under repetitive impact loads\u003c\/li\u003e\n  \u003cli\u003eBall lock style retention for secure, repeatable seating in compatible punch retainers\u003c\/li\u003e\n  \u003cli\u003eSolid blank form allows secondary grinding to custom punch profiles\u003c\/li\u003e\n  \u003cli\u003e0.5-inch shank diameter with 4.25-inch overall length for standard die set fitment\u003c\/li\u003e\n  \u003cli\u003eJektole (HJB) series for consistent dimensional standards across the product line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or tooling component for progressive die sets and mold die assemblies requiring a ball lock, solid blank punch with a 0.5-inch shank diameter in the Jektole (HJB) series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tool and die makers or press room technicians familiar with punch and die assembly procedures. Power down and lock out all press equipment before removing or installing punch components. Ensure the punch retainer is compatible with the ball lock retention style before seating the punch. Secondary machining of the blank should be completed before installation to achieve the required punch geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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 Style\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\u003eUNSPSC Code\u003c\/strong\u003e: 31162807\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 pounds\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 50 425 M2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":52036436721970,"sku":"HJB 50 425 M2","price":93.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022db6a99734ab31d2a4e8c43e036490_5b861263-ba35-45d2-bfda-38c531bdd710.jpg?v=1790023862","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-hjb-50-425-m2-solid-mold-die-blank-punch","provider":"Voomi Supply","version":"1.0","type":"link"}
