ER collets are precision workholding components used in CNC machining centers, manual milling machines, and lathes to grip cutting tools or workpieces concentrically within a collet chuck. The tight TIR rating on this collet supports accurate material removal and consistent tool positioning during high-speed or precision cutting operations. Machinists and toolroom technicians rely on ER40 collets for their broad clamping range and compatibility with widely available ER40 chucks.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in machine shops, production environments, and toolroom applications where a 0.125-inch tool shank must be held securely in an ER40 collet chuck. The ER40 series accommodates a range of bore sizes, making these collets a common choice for general-purpose CNC and manual machining setups in both job-shop and production-line contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series for use with standard ER40 collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.125-inch (1\/8-inch) collet bore size for precise tool shank gripping\u003c\/li\u003e\n  \u003cli\u003e0.0005-inch TIR for accurate, concentric tool runout performance\u003c\/li\u003e\n  \u003cli\u003eCompact form factor weighing 0.66 pounds\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for direct toolroom or machine-side use\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 use with standard ER40 collet chucks in CNC and manual machining applications requiring a 0.125-inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing any collet. Seat the collet fully into the ER40 chuck nut before threading onto the spindle to avoid damage to the collet or chuck. Inspect the collet bore and chuck taper for debris or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (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: 0.66 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: 204-4008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690203611442,"sku":"204-4008","price":27.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a58fa4128ebdc0b9481d4feec612823a.jpg?v=1788267263","url":"https:\/\/voomisupply.com\/products\/value-collection-204-4008-er40-collet-0-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
