It accepts round workpieces at a 25.00 mm collet size and delivers a total indicated runout (TIR) of 0.015 mm, making it suitable for precision turning, grinding, and milling setups where concentricity matters. 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. Weighing 0.5 pounds, it is a direct drop-in form factor for standard 5C tooling systems used in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis collet is intended for use in machine shops, toolrooms, and manufacturing cells running lathes, grinders, or rotary indexers equipped with 5C spindle noses. It is suited for holding round bar stock or turned workpieces during precision machining operations. Machinists, tool-and-die makers, and CNC setup technicians are the primary installers. Steel construction provides the rigidity and wear resistance required for repeated clamping cycles in continuous production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e25.00 mm collet size for round workpiece clamping\u003c\/li\u003e\n\u003cli\u003eTIR of 0.015 mm for precision concentricity control\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and rigidity under clamping load\u003c\/li\u003e\n\u003cli\u003eInternal thread: 1.041 inches, 24 threads per inch\u003c\/li\u003e\n\u003cli\u003eExternal thread: 1.242 inches, 20 threads per inch\u003c\/li\u003e\n\u003cli\u003eStandard 5C form factor compatible with common spindle tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5C-style round collet for use in 5C-compatible spindles, chucks, and collet closers commonly found on manual and CNC lathes and indexing fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with 5C collet systems. Power down and lock out the machine spindle before inserting or removing the collet. Ensure the collet bore and spindle taper are clean and free of chips or burrs before seating. Do not exceed the rated collet size, as overloading the collet jaws can compromise TIR and damage the collet or spindle nose.\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: 25.00 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 inches, 24 threads per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.242 inches, 20 threads per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 1230-4247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694355153202,"sku":"1230-4247","price":40.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4b524385f63a746a8639011c41e3f22.jpg?v=1788323537","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4247-5c-round-collet-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
