Rated at 0.0005 inches Total Indicated Runout (TIR), this collet holds tight tolerances required for accurate tool positioning in high-speed spindle work. It accepts tooling up to 0.078 inches (1.98mm) in diameter with a minimum collet capacity of 0.059 inches (1.5mm). The compact form factor measures 1.06 inches in length and 0.71 inches in diameter, making it suitable for standard ER16-compatible spindle and toolholder systems. At 0.15 pounds, it is lightweight and easy to handle during tool changes. Machinists and CNC operators working with small-diameter end mills, drills, and reamers rely on this collet for consistent, repeatable clamping force.\u003c\/p\u003e\u003cp\u003eThis collet is intended for use in ER16-compatible collet chucks installed on CNC machining centers, milling machines, and routing equipment requiring precise small-diameter tool retention. It is suited for production environments where low TIR is critical to surface finish and dimensional accuracy. Typical users include machine shop technicians and CNC programmers working with fine tooling in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER16 collet series with 0.0005 inches TIR for precision tool retention\u003c\/li\u003e\n\u003cli\u003eAccepts tool diameters from 0.059 inches (1.5mm) up to 0.078 inches (1.98mm)\u003c\/li\u003e\n\u003cli\u003eCompact dimensions: 1.06 inches length, 0.71 inches width and height\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.15 pounds for fast, easy tool changes\u003c\/li\u003e\n\u003cli\u003eSold individually, quantity of one per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard ER16-compatible collet chucks and toolholders accepting the ER16 collet series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing collets. Clean the collet seat and nut threads before installation to prevent runout caused by contamination. Do not exceed the rated clamping torque specified by the toolholder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (mm)\u003c\/strong\u003e: 1.98mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.059 inches (1.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U102771\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51752321515826,"sku":"U102771","price":93.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/227a711fc3d6dd4f81329d66dedc558d.jpg?v=1788927434","url":"https:\/\/voomisupply.com\/products\/sumitomo-u102771-er16-collet-0-078-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
