This collet accepts 3\/4-inch square workpieces and holds them with a total indicator runout (TIR) of 0.0005 inches, providing the repeatable, precise workholding that precision turning and milling operations demand. Constructed from steel, the 530-4248 features an internal thread size of 1.041 inches-24 and an external thread size of 1.242 inches-20, conforming to standard 5C collet geometry for direct drop-in use on compatible spindles. Machinists and toolroom technicians install this collet in production and job-shop environments where consistent grip on square stock is required.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in manual and CNC lathes, collet blocks, spin indexers, and other 5C-compatible workholding equipment. It is appropriate for light to medium-duty turning, facing, and secondary operations on square bar stock up to 3\/4 inch. The square bore geometry prevents workpiece rotation during machining, making it a common choice for operations that require indexed or oriented clamping on square material in both production and prototype settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch square bore for positive, rotation-resistant grip on square stock\u003c\/li\u003e\n  \u003cli\u003e0.0005-inch TIR for precise, repeatable workholding\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in machine shop environments\u003c\/li\u003e\n  \u003cli\u003e1.041 inches-24 internal thread matches standard 5C collet specification\u003c\/li\u003e\n  \u003cli\u003e1.242 inches-20 external thread for standard 5C closer and chuck compatibility\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 1 for single-unit purchase flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5C-specification square collet for use in any 5C collet chuck, collet closer, spin indexer, or collet block that accepts the 1.242 inches-20 external thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before installing or removing the collet, power down the machine and ensure the spindle has come to a complete stop. Thread the collet into the closer or chuck by hand first to confirm clean thread engagement before applying a collet wrench. Inspect the collet bore and workpiece surfaces for chips or burrs prior to clamping, as contamination directly affects runout and workholding accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: 5C Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1.041 inches-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 inches-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 530-4248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702445539634,"sku":"530-4248","price":41.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8dd469d99742b420f2e6635d1ce7afb.jpg?v=1788410859","url":"https:\/\/voomisupply.com\/products\/value-collection-530-4248-5c-square-steel-collet-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
