It features a 1.041 inch-24 internal thread and a 1.242 inch-20 external thread, with a total indicator runout (TIR) of 0.015 mm for consistent concentricity during turning and grinding operations. The collet size is 16.50 mm. This part is installed and used by machinists and toolroom technicians in production and job-shop environments where repeatable workholding is required.\u003c\/p\u003e\n\u003cp\u003eThis 5C round collet is suited for manual and CNC lathe setups that use the 5C collet system. It is appropriate for holding round bar stock and cylindrical workpieces in applications where precision runout control is critical. The 5C format is widely used in both light production turning and precision grinding work across job shops, toolrooms, and manufacturing facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet format for compatibility with standard 5C collet-equipped spindles and chucks\u003c\/li\u003e\n  \u003cli\u003e16.50 mm collet size for holding round workpieces to that diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003e1.041 inch-24 internal thread and 1.242 inch-20 external thread for proper spindle engagement\u003c\/li\u003e\n  \u003cli\u003e0.015 mm TIR for consistent concentricity in precision turning and grinding setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5C round collet replacement or addition for lathes, collet chucks, and spin fixtures built to accept the 5C collet system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Before inserting or removing a collet, power down the spindle completely and confirm the machine is in a safe, locked-out state. Inspect the collet seat and spindle bore for chips or debris before seating the collet, as contamination will directly affect runout. Do not overtighten the collet closer, as this can deform the collet and damage the thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 16.50 mm\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\u003eTIR\u003c\/strong\u003e: 0.015 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1230-4230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714942370098,"sku":"1230-4230","price":40.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8e05abb0aa3b64179f8df0990a70a2a.jpg?v=1788508164","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4230-5c-round-collet-16-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
