It accepts a 9\/32 inch round shank and features a 1.988-20 external thread for secure mounting in compatible collet chucks and toolholding systems. The overall length measures 3-3\/4 inches, and the collet holds a maximum total indicator runout (TIR) of 0.0007 inches, making it suitable for applications where concentricity and repeatability are critical. Machinists and toolroom technicians install this collet in precision turning, milling, and grinding setups where tight tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in machine shop environments ranging from small job shops to production facilities. It fits toolholding systems that accept the 1.988-20 external thread specification. Typical applications include holding round-shank cutting tools, drill bits, and workpieces in CNC lathes, machining centers, and grinding machines where low runout directly affects surface finish and dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/32 inch bore accepts standard round-shank tooling\u003c\/li\u003e\n  \u003cli\u003e1.988-20 external thread for secure chuck engagement\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inch overall length provides adequate reach for typical toolholding setups\u003c\/li\u003e\n  \u003cli\u003e0.0007 inch TIR supports precision concentricity requirements\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 27112800 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for toolholding systems that accept a 1.988-20 external thread round collet configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before installing or removing collets. Use the appropriate collet wrench or chuck key for the specific toolholding system to achieve proper seating and clamping force. Inspect the collet bore and chuck threads for debris or damage before installation to maintain the specified TIR.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize (Bore)\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1.988 inches-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.68 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: LYNDEX-NIKKEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LYNDEX-NIKKEN","offers":[{"title":"Default Title","offer_id":67906755395890,"sku":"300-018","price":112.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a1f8fe2bed81b04260c674ba9a56fb4.jpg?v=1791171149","url":"https:\/\/voomisupply.com\/products\/lyndex-nikken-300-018-round-collet-9-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
