It accepts round workpieces and provides consistent gripping force for turning, grinding, and secondary operations on lathes and rotary fixtures. The collet 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 reliable concentricity in production and toolroom environments. Machinists and tool-room operators select this collet for its straightforward fitment into standard 5C tooling systems.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for metalworking applications where precise workholding is required on CNC lathes, manual engine lathes, and indexing fixtures that accept 5C-style collets. The 2.50 mm collet size accommodates small-diameter round stock, making it a practical choice for screw machine work, small-part turning, and similar precision operations. It is installed and serviced by machinists and tool-room technicians in job shops, production facilities, and maintenance departments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet design compatible with standard 5C spindle noses and collet chucks\u003c\/li\u003e\n  \u003cli\u003e2.50 mm collet size for small-diameter round workpiece clamping\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003e0.015 mm TIR for consistent concentricity and part accuracy\u003c\/li\u003e\n  \u003cli\u003e1.041 inch-24 internal thread and 1.242 inch-20 external thread for positive engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment collet for standard 5C collet chucks, spindle noses, and rotary fixtures that accept the 5C collet series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Before inserting or removing the collet, ensure the lathe or fixture spindle is fully stopped and the machine is powered down. Use the appropriate collet closer or draw tube wrench to seat and tighten the collet to the spindle; do not strike the collet with a hammer or apply force to the workpiece to drive the collet into the spindle. Inspect the collet bore and spindle taper for chips or debris before each use to maintain TIR performance.\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 Series\u003c\/strong\u003e: 5C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 2.50 mm\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: 0.015 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\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: 1230-4202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51783608434994,"sku":"1230-4202","price":41.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/989db3583c591371887ef82b014e0c9d.jpg?v=1789191799","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4202-5c-round-collet-2-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
