It features an internal thread size of 1.041 inches-24 and an external thread size of 1.242 inches-20, allowing it to seat and draw correctly within compatible 5C spindles and closers. With a collet size of 11.50mm and a total indicator runout (TIR) of 0.015mm, this collet delivers the concentricity needed for precision turning and grinding operations. It is suited for machinists and toolroom professionals working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis collet is intended for use in 5C collet-compatible machine tool spindles found in manual and CNC lathes, surface grinders, and indexing fixtures. The round collet profile accommodates round bar stock and workpieces, making it a standard choice for general turning and chucking applications. It is a direct fit for setups where 5C tooling is already in use and a specific collet size of 11.50mm is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5C round collet profile for use in standard 5C spindles and closers\u003c\/li\u003e\n\u003cli\u003e11.50mm collet size for precise workholding of round stock\u003c\/li\u003e\n\u003cli\u003eTIR of 0.015mm for consistent concentricity in precision machining\u003c\/li\u003e\n\u003cli\u003eInternal thread: 1.041 inches-24\u003c\/li\u003e\n\u003cli\u003eExternal thread: 1.242 inches-20\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or toolroom addition for machine tools equipped with 5C collet spindles and closer systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with 5C collet systems. Ensure the spindle and collet closer are fully de-energized and the machine is locked out before inserting or removing the collet. Clean the spindle bore and collet taper of chips and debris before seating the collet to maintain runout accuracy. Do not force the collet into the spindle; proper engagement is hand-tight before actuating the closer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: 5C Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 11.50mm\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: 0.015mm\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1230-4220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692667404594,"sku":"1230-4220","price":40.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/661dba01872ec9c9e6de7cc9706113ee.jpg?v=1788300852","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4220-5c-round-collet-11-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
