With a collet size of 1.50 mm and a total indicated runout (TIR) of 0.015 mm, this collet provides consistent, repeatable workholding precision for turning, milling, 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. It is installed by machinists and toolroom technicians on manual lathes, CNC turning centers, and bench-top fixtures that accept the 5C collet standard.\u003c\/p\u003e\u003cp\u003eThis collet is suited for production and maintenance machining environments where close-tolerance workholding is required. Typical applications include holding small-diameter round bar stock, pins, shafts, and similar cylindrical parts for turning or secondary operations. The steel construction provides durability under repeated clamping cycles. At 0.5 pounds, the part is lightweight and easy to handle during tool changes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5C round collet format — fits standard 5C spindles and collet closers\u003c\/li\u003e\n\u003cli\u003eCollet size: 1.50 mm for precise small-diameter workholding\u003c\/li\u003e\n\u003cli\u003eTIR of 0.015 mm for consistent runout performance\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated use\u003c\/li\u003e\n\u003cli\u003eInternal thread: 1.041 inches-24; external thread: 1.242 inches-20\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use collet for machine tools equipped with a standard 5C collet spindle interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003e5C collets are installed and removed by machinists following standard lathe or collet-closer lockout and de-energization procedures. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the collet. Threads should be clean and free of chips before installation. Consult the machine tool manufacturer documentation for proper draw-tube torque and collet-closer adjustment procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.50 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\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: 1230-4200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720229028146,"sku":"1230-4200","price":42.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30e18089193b0b53069e63361234c44f.jpg?v=1788561738","url":"https:\/\/voomisupply.com\/products\/value-collection-1230-4200-5c-round-collet-1-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
