It accepts workpieces up to 8.00 millimeters and delivers a total indicated runout (TIR) of 0.015 millimeters, providing 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. At 0.5 pounds, it is a standard-weight collet suited for production and tool-room environments. Machinists and machine tool technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis collet is intended for use in production turning centers, manual engine lathes, and surface or cylindrical grinding machines that accept the 5C collet system. The round profile is the most common 5C style and is used to grip round bar stock, pins, and shaft workpieces for facing, turning, drilling, and light milling operations. It is a practical choice for shops running mixed-diameter work in the small-diameter range on 5C-equipped machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound collet profile for gripping cylindrical workpieces up to 8.00 millimeters\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability under repeated clamping cycles\u003c\/li\u003e\n\u003cli\u003eTIR of 0.015 millimeters supports concentricity-sensitive operations\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\u003eStandard 5C form factor fits a wide range of compatible spindles and closers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production collet for machine tools equipped with a standard 5C collet spindle system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or machine tool technician. Before inserting or removing the collet, disengage the machine spindle drive and confirm the machine is fully powered down and locked out per facility lockout\/tagout procedures. Inspect the collet bore, taper, and threads for chips or burrs before seating, as contamination directly affects runout. Do not exceed the rated capacity of the collet or apply impact force during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 8.00 millimeters\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 millimeters\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1230-4213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699675857202,"sku":"1230-4213","price":40.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55fa63b16b330d88a4d31174a3f106cc.jpg?v=1788379069","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4213-5c-round-collet-8mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
