Emergency collets are supplied with an unfinished or undersized bore so the operator can bore and finish the interior to a custom diameter on the machine, achieving precise concentricity for specialized or non-standard workholding. This collet features a 1\/16 inch pilot hole, an internal thread size of 1.041 inches at 24 threads per inch, and an external thread size of 1.242 inches at 20 threads per inch. Total indicated runout (TIR) is 0.00315 inches. It is installed by machinists, toolroom technicians, and CNC setup specialists.\u003c\/p\u003e\n\u003cp\u003eEmergency collets in the 5C format are used across job shops, toolrooms, and production machining environments wherever a standard finished-bore collet cannot accommodate an unusual part diameter or geometry. The open pilot hole and machinable construction allow the technician to bore the collet to a precise fit on the host machine, ensuring accurate part alignment. This collet suits both manual and CNC lathes equipped with a 5C spindle nose or collet closer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMachinable emergency design allows boring to a custom internal diameter on the machine for precise, concentric workholding\u003c\/li\u003e\n  \u003cli\u003eTotal indicated runout (TIR) of 0.00315 inches for accurate part registration\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability in production and toolroom environments\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch (0.0625 inch) pilot hole for initial location during boring operations\u003c\/li\u003e\n  \u003cli\u003eInternal thread: 1.041 inches at 24 TPI; external thread: 1.242 inches at 20 TPI\u003c\/li\u003e\n  \u003cli\u003eConforms to standard 5C collet geometry for broad spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5C-format emergency collet suitable for lathes and collet closers that accept the 5C collet system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and boring of emergency collets should be performed by a qualified machinist or toolroom technician. Before mounting, ensure the spindle is fully stopped and the machine is locked out according to applicable safety procedures. The collet should be bored to the required internal diameter while seated in the host machine spindle or a dedicated collet fixture to ensure true concentricity. Do not exceed the clamping force or speed ratings specified by the machine manufacturer for the 5C collet system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Emergency (5C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Indicated Runout (TIR)\u003c\/strong\u003e: 0.00315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Hole Size\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1.041 inches at 24 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 inches at 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.77 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: 230-4395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695182741810,"sku":"230-4395","price":30.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7c3aec52096c08ee34755924bc6ac3d.jpg?v=1788332201","url":"https:\/\/voomisupply.com\/products\/value-collection-230-4395-5c-emergency-collet","provider":"Voomi Supply","version":"1.0","type":"link"}
