Sized at 3\/8 inch, it holds round stock with a total indicator runout (TIR) of 0.0005 inches, delivering the concentricity required for precision turning and grinding operations. The internal thread measures 1.041 inch-24 and the external thread measures 1.242 inch-20, conforming to standard 5C geometry. Machinists and tool-room technicians install this collet as part of a standard 5C workholding setup.\u003c\/p\u003e\u003cp\u003eThis collet is suited for production and tool-room environments where consistent, repeatable workholding on round bar stock is required. It is appropriate for light-duty to medium-duty turning, drilling, and grinding passes on round material at the 3\/8 inch nominal diameter. The steel construction provides durability under repeated clamping cycles and normal machine-shop operating conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch round capacity for standard 5C spindle applications\u003c\/li\u003e\n\u003cli\u003e0.0005 inch TIR for high-concentricity workholding\u003c\/li\u003e\n\u003cli\u003e1.041 inch-24 internal thread per standard 5C specification\u003c\/li\u003e\n\u003cli\u003e1.242 inch-20 external thread per standard 5C specification\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 direct-fit collet for machine tools equipped with a standard 5C collet spindle or chuck system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003e5C collets are installed and removed by qualified machinists using the drawbar or lever-close mechanism of the host machine. Power the spindle down completely and follow lockout\/tagout procedures before inserting or removing any collet. Inspect the collet bore and spindle nose for chips or burrs prior to installation, as debris will directly degrade runout. Do not exceed the collet nominal capacity or use shims to force oversized stock.\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: 3\/8 inch\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 inch-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 inch-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.59 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: 230-4124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698016059698,"sku":"230-4124","price":26.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57afdd16c8fc97b49ee0077ac9bd8011.jpg?v=1788356766","url":"https:\/\/voomisupply.com\/products\/value-collection-230-4124-5c-steel-collet-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
