It accepts round workpiece stock and provides a total indicator reading (TIR) of 0.015 mm, delivering consistent concentricity for precision turning and grinding operations. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C collet geometry. This collet weighs 0.5 pounds and is suited for production and tool-room environments where repeatable workholding accuracy is required. Machinists and tool-room technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in manual and CNC lathes, cylindrical grinders, and indexing fixtures equipped with 5C spindle noses. It is appropriate for both light production runs and precision single-piece work where round bar stock or round-shank tooling must be held concentrically. The 9 mm collet size accommodates round stock at that diameter. It is a common workholding component in job shops, tool rooms, and production machine shops handling small-diameter turned parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet profile fits standard 5C spindle noses and collet chucks\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015 mm for consistent concentricity in turning and grinding\u003c\/li\u003e\n  \u003cli\u003eCollet size: 9 mm round capacity\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 in production workholding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5C-style round collet for use in any machine spindle or collet chuck built to 5C collet specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool-room technicians. The spindle must be stationary and the machine powered down before inserting or removing the collet. Inspect the collet bore and spindle taper for chips or debris before seating the collet, as contamination directly affects TIR. Do not exceed the rated collet capacity, as oversize stock will damage the collet and the spindle nose.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.015 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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 1230-4215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721028665650,"sku":"1230-4215","price":40.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792d2c104fc082adb02306cd2ed71af5.jpg?v=1788572505","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4215-5c-round-collet-9mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
