Machined from steel, this collet accepts round workpieces and is sized at 20.00 mm (approximately 0.787 inches). The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to the standard 5C collet interface. Total indicated runout (TIR) is rated at 0.015 mm, providing the repeatable concentricity required for production turning and grinding setups. This collet is used by machinists and tool-room technicians working with lathes, grinders, and indexing fixtures equipped with 5C spindle noses.\u003c\/p\u003e\n\u003cp\u003eThe 230-4220 is suited for production and job-shop environments where 5C collet tooling is the standard workholding method. Common applications include bar-feed turning, cylindrical grinding, and rotary table indexing on mills. The 20.00 mm capacity makes it appropriate for metric round stock within that diameter range. It is a direct-fit replacement for any 5C round collet of equivalent size in shops running 5C-compatible lathes, grinders, or collet fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard 5C round collet configuration for broad machine compatibility\u003c\/li\u003e\n  \u003cli\u003e20.00 mm collet size accommodates round workpieces of that diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.015 mm supports consistent concentricity in turning and grinding operations\u003c\/li\u003e\n  \u003cli\u003e1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C spindle interfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for standard 5C round collets used in 5C-compatible lathes, cylindrical grinders, and indexing fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Use the appropriate collet closer or draw tube for the specific machine spindle to avoid thread damage. Inspect the collet bore and spindle nose for chips or burrs before seating the collet. Follow the machine manufacturer guidelines for clamping force to avoid distorting the collet.\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: 20.00 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\u003eTIR\u003c\/strong\u003e: 0.015 mm\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: 0.52 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: 230-4220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722726474034,"sku":"230-4220","price":45.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2c0d0c42bfaf43252ded9e37788377e.jpg?v=1788595026","url":"https:\/\/voomisupply.com\/products\/value-collection-230-4220-5c-round-collet-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
