Manufactured from steel, it holds round stock at a nominal bore size of 1-7\/64 inches with a total indicator runout (TIR) of 0.0005 inches, making it suitable for close-tolerance turning, grinding, and secondary machining operations. The internal thread measures 1.041-24 and the external thread measures 1.242-20, conforming to standard 5C dimensional specifications. Machinists and tool room technicians install this collet where repeatable concentricity and secure workholding are required on production or manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis collet is intended for use in machine shop environments where 5C-compatible spindles, collet closers, or rotary fixtures are in service. It is well suited for holding round bar stock, slugs, or turned parts during lathe operations, cylindrical grinding, or milling in a 5C collet block. The 0.0005-inch TIR rating supports applications where part runout directly affects finished dimensions or surface finish requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/64 inch bore diameter for round workholding\u003c\/li\u003e\n  \u003cli\u003e0.0005 inch TIR for precise concentricity\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003e1.041-24 internal thread conforms to 5C collet standard\u003c\/li\u003e\n  \u003cli\u003e1.242-20 external thread conforms to 5C collet standard\u003c\/li\u003e\n  \u003cli\u003eRound collet style for cylindrical stock and parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment for machine tool spindles, collet chucks, and fixtures built to accept the standard 5C collet form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool room technicians familiar with 5C collet systems. Before inserting or removing the collet, disengage the collet closer and ensure the spindle is fully stopped and locked out per shop lockout\/tagout procedures. Inspect the collet bore and spindle taper for chips or burrs before seating the collet, as debris will directly affect runout. Do not exceed the rated bore size or apply collet closers beyond the torque appropriate for the workpiece material and diameter.\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\u003eBore Size\u003c\/strong\u003e: 1-7\/64 inches\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: 1.041-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242-20\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: 0.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 230-4307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700678852914,"sku":"230-4307","price":26.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1656559f672e67664438cd36dd1b370d.jpg?v=1788393725","url":"https:\/\/voomisupply.com\/products\/value-collection-230-4307-5c-round-collet-1-7-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
