It uses a ball lock retention system to hold the punch shank firmly during high-cycle stamping and forming operations. The retainer features a 0.75-inch shank diameter and a base measuring 1.875 inches long by 1.875 inches wide by 1.25 inches tall. Thread size is 3\/8-16. With a weight of 1 pound, this component is sized for medium-duty tooling applications. Tool and die makers and precision machining professionals specify this retainer when building or maintaining progressive die sets that require reliable, repeatable punch positioning.\u003c\/p\u003e\n\u003cp\u003eThe LRS 75 retainer fits into press tooling assemblies where punch changeability and precise alignment are required. The ball lock design allows for faster punch swaps compared to screw-type retainers, reducing downtime during die maintenance. The 5\/16-inch dowel diameter provides positive angular location of the punch, and the 0.562-inch punch shank-to-dowel length establishes the correct positional relationship between components. This part is appropriate for use in both prototype and production tooling environments across metal stamping, forming, and progressive die applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall lock retention system for secure, repeatable punch holding\u003c\/li\u003e\n  \u003cli\u003e0.75-inch shank diameter with 1.5-inch thread length on 3\/8-16 threads\u003c\/li\u003e\n  \u003cli\u003e1.875 inches x 1.875 inches x 1.25 inches base dimensions for stable tooling integration\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch dowel diameter for precise angular punch location\u003c\/li\u003e\n  \u003cli\u003e1.125-inch length between dowel and screw for consistent punch-to-retainer geometry\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for durability in high-cycle press operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification component for progressive die sets and mold assemblies requiring a 0.75-inch shank ball lock punch retainer with 3\/8-16 thread and a 5\/16-inch dowel diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tool and die makers or precision machining technicians. The press must be fully de-energized and locked out before any die work is performed, in compliance with applicable OSHA lockout\/tagout procedures. Ensure all mating surfaces are clean and free of burrs before seating the retainer. Do not force the ball lock mechanism  -  verify punch shank diameter and retainer bore compatibility before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePunch Shank To Dowel Length\u003c\/strong\u003e: 0.562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Between Dowel and Screw\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetention Type\u003c\/strong\u003e: Ball Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: LRS 75\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":67988493369650,"sku":"LRS 75","price":82.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3780348e8369c48f3fc5c5de6b913037_39e93315-4f01-4cd1-bec8-2eccc7604250.jpg?v=1792297360","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-lrs-75-mold-punch-retainer-ball-lock","provider":"Voomi Supply","version":"1.0","type":"link"}
