With a 0.125 inch (1\/8 inch) bore diameter and a total indicator runout (TIR) of 0.0005 inches, this collet provides the precision grip necessary for accurate cutting tool retention. It is installed and serviced by machinists and CNC technicians working in production and job-shop environments where consistent tool runout directly affects part quality and surface finish.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for light-duty to medium-duty milling, drilling, engraving, and routing applications where a 1\/8 inch shank tool must be held securely. The ER16 form factor is widely used in compact spindles and toolholding chucks across both manual and CNC machine platforms. It is a standard single-piece collet sold individually, making it practical as a direct replacement or as an addition to an existing ER16 collet set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series for use with ER16-compatible chucks and spindles\u003c\/li\u003e\n  \u003cli\u003e0.125 inch (1\/8 inch) bore accommodates standard 1\/8 inch shank cutting tools\u003c\/li\u003e\n  \u003cli\u003e0.0005 inch TIR for precise tool concentricity and reduced runout\u003c\/li\u003e\n  \u003cli\u003eSold individually, no minimum set purchase required\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.09 pounds for easy handling and quick changeout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental collet for use with ER16-compatible collet chucks and toolholding systems accepting 1\/8 inch shank tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC technicians. Always power down and lock out the machine spindle before installing or removing a collet. Seat the collet fully into the ER16 chuck nut before threading onto the spindle, and torque the nut with the appropriate ER collet wrench to manufacturer specifications for the chuck being used. Inspect the collet bore and chuck taper for debris or damage before each installation to maintain TIR performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Type\u003c\/strong\u003e: ER Collet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Fractional Inch)\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 204-1608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697179001138,"sku":"204-1608","price":22.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/557ac132e784cfba2b191578f55470dd.jpg?v=1788350299","url":"https:\/\/voomisupply.com\/products\/value-collection-204-1608-er16-collet-1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
