It accepts round workpieces and provides a Total Indicator Runout (TIR) of 0.015 mm, delivering the concentricity required for precision turning and grinding operations. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread measures 1.242 inches at 20 threads per inch. Machinists and tool-room technicians install this collet when holding round stock or finished cylindrical parts where accuracy and repeatability matter.\u003c\/p\u003e\n\u003cp\u003eThis 5C round collet is suited for use in manual lathes, CNC lathes with 5C nose attachments, rotary tables, and collet blocks in a machine shop environment. It is a standard 5C-format collet, making it compatible with the broad range of 5C-compatible workholding equipment found in both job shops and production environments. The 27 mm collet size accommodates round stock at that nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5C round collet format fits standard 5C workholding systems\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015 mm for precise, repeatable concentricity\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under normal machining loads\u003c\/li\u003e\n  \u003cli\u003eInternal thread: 1.041 inches at 24 threads per inch\u003c\/li\u003e\n  \u003cli\u003eExternal thread: 1.242 inches at 20 threads per inch\u003c\/li\u003e\n  \u003cli\u003e27 mm collet size for round workpiece clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5C-format replacement or spare collet for use in 5C collet chucks, collet blocks, and rotary fixtures that accept the 5C collet standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool-room technicians. Power down and lock out the machine spindle before inserting or removing the collet. Ensure the collet bore, chuck nose, and draw tube threads are clean and free of chips before seating the collet. Do not exceed the collet's rated capacity, as overloading a collet bore can cause workpiece slippage and damage the collet taper.\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: 27 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\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: 1230-4251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692822004018,"sku":"1230-4251","price":40.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f3bdbe2ef38a2d978bf66cba54edc5f.jpg?v=1788303498","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4251-5c-round-collet-27mm","provider":"Voomi Supply","version":"1.0","type":"link"}
