It accepts round workpieces and provides a total indicator runout (TIR) of 0.015 mm, making it suitable for applications that require consistent workpiece concentricity. The internal thread measures 1.041-24 and the external thread measures 1.242-20, conforming to standard 5C collet dimensions. Weighing 0.5 pounds, this collet is a straightforward drop-in for shops running 5C tooling setups.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in machine shops, toolrooms, and manufacturing environments where 5C spindle tooling is the standard. It is appropriate for manual lathes, CNC lathes with 5C-compatible headstocks, collet closers, and indexing fixtures that accept the 5C form factor. Typical installers are machinists and tool-and-die professionals performing workholding setup on production or job-shop turning equipment. The 12.50 mm collet size accommodates round bar stock or parts near that diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet form factor — compatible with standard 5C spindles and chucks\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015 mm for reliable concentricity in precision turning operations\u003c\/li\u003e\n  \u003cli\u003eInternal thread size: 1.041-24\u003c\/li\u003e\n  \u003cli\u003eExternal thread size: 1.242-20\u003c\/li\u003e\n  \u003cli\u003eCollet size: 12.50 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or addition for machine tool setups using 5C collet spindles, collet chucks, and collet closers that accept the 5C form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool setup personnel. Before inserting or removing a collet, ensure the lathe or machine spindle is fully powered down and the drawbar or collet closer is fully released. Inspect the collet bore and spindle taper for chips or contamination before seating the collet. Do not force the collet into the spindle; proper engagement should require only hand pressure followed by normal drawbar torque per the machine manufacturer's specifications.\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 Size\u003c\/strong\u003e: 12.50 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 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\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: 1230-4222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719102234930,"sku":"1230-4222","price":40.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4acffbb8ef3df2c43e04d4336447b477.jpg?v=1788557455","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4222-5c-round-collet-12-50mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
