It features a 1.988-20 external thread for secure chuck engagement and an overall length of 3.75 inches, making it suitable for standard production machining setups. Weighing 1.67 pounds, this collet provides the rigidity required for milling, drilling, and turning operations where square stock retention is critical. Machinists and tooling technicians working on CNC or manual machine tools will find this collet a reliable component for accurate, repeatable clamping.\u003c\/p\u003e\n\u003cp\u003eThis square collet is intended for use in machine shop environments where square-profile workholding is required. It is appropriate for both production and job-shop applications involving CNC machining centers or manual milling machines that accept collet chuck systems with a 1.988-20 external thread interface. The 1-inch square bore accommodates 1-inch square stock or tooling directly, without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch square bore for direct retention of 1-inch square stock or tooling\u003c\/li\u003e\n  \u003cli\u003e1.988-20 external thread for positive chuck engagement\u003c\/li\u003e\n  \u003cli\u003e3.75-inch overall length for standard reach in collet chuck assemblies\u003c\/li\u003e\n  \u003cli\u003e1.67-pound construction offering solid rigidity during machining operations\u003c\/li\u003e\n  \u003cli\u003eSquare collet profile prevents workpiece rotation under cutting loads\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 square collet configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this collet should be performed by a qualified machinist or tooling technician familiar with collet chuck assembly procedures. Always ensure the machine spindle is fully powered down and the chuck is removed from the spindle before inserting or removing collets. Inspect the collet bore and thread for debris or damage before assembly. Tighten the chuck nut to the toolholder manufacturer's specified procedure using appropriate spanner wrenches  -  do not use pipe extensions or impact tools on collet nuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1 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: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.67 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: 340-064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LYNDEX-NIKKEN","offers":[{"title":"Default Title","offer_id":67918467563826,"sku":"340-064","price":136.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0099d38fc38a7e4b09a02f10dfb697e.jpg?v=1791270129","url":"https:\/\/voomisupply.com\/products\/lyndex-nikken-340-064-square-collet-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
