The collet accepts a 4.00 mm workpiece and holds it with a total indicated runout (TIR) of 0.015 mm, making it suitable for precision turning, grinding, and secondary operations. The internal thread measures 1.041 in-24 and the external thread measures 1.242 in-20, conforming to standard 5C interface dimensions. It is installed and used by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis collet is intended for use in any 5C-compatible spindle nose, collet chuck, collet block, or fixture that accepts the standard 5C external thread and nose profile. Typical applications include holding round bar stock, shafts, and cylindrical workpieces during turning, milling in a collet block, or inspection. The 4.00 mm bore size suits small-diameter precision work common in medical, aerospace, and general metalworking settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet configuration compatible with standard 5C spindle systems\u003c\/li\u003e\n  \u003cli\u003e4.00 mm collet bore for small-diameter round workholding\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015 mm for repeatable, close-tolerance gripping\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003e1.041 in-24 internal thread and 1.242 in-20 external thread match standard 5C dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5C collet spindles, chucks, and fixtures that accept the 1.242 in-20 external thread 5C profile.

Before inserting or removing a collet, ensure the machine spindle is fully stopped and the draw tube or closer mechanism is released. Inspect collet bore and seating surfaces for chips or burrs before seating, as contamination directly affects runout and grip force. Do not exceed the rated bore diameter, as overloading the collet can permanently distort the split segments.\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 Bore Size\u003c\/strong\u003e: 4.00 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 in-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 in-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\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: 1230-4205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712275448114,"sku":"1230-4205","price":40.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/680f1ccead8dc7151f73e8f63758af6b.jpg?v=1788485885","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4205-5c-round-collet-4-00mm","provider":"Voomi Supply","version":"1.0","type":"link"}
