It accepts a 0.125 inch (1\/8 inch) shank diameter and holds a maximum total indicator runout (TIR) of 0.0004 inches, making it suitable for precision machining applications where concentricity and repeatability are critical. Weighing 0.5 pounds, this collet is a standard ER32 format component installed by machinists and tool room technicians in both production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis collet fits any ER32-compatible collet chuck or toolholder, making it appropriate for a wide range of horizontal and vertical machining center setups. It is commonly used in milling, drilling, reaming, and tapping operations where a 0.125 inch shank tool must be held with minimal runout. Suitable for both light and moderate-duty cutting operations across metals, plastics, and composites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER32 collet series for broad compatibility with ER32-standard collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.125 inch (1\/8 inch) bore diameter for precise tool shank retention\u003c\/li\u003e\n  \u003cli\u003e0.0004 inch maximum TIR for high concentricity and repeatable tool positioning\u003c\/li\u003e\n  \u003cli\u003e0.5 pound weight for easy handling and straightforward chuck installation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging for individual replacement or tooling buildout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ER32-format collet for use in any ER32-compatible collet chuck or toolholding system accepting a 0.125 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool room technicians. The spindle or machine must be powered down and brought to a complete stop before changing collets. Ensure the collet chuck nut, collet groove, and chuck bore are clean and free of chips or debris before seating the collet. Use a properly sized collet wrench and chuck wrench to torque the nut — do not use improvised tools that can damage the collet or nut threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER32\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: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4503831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728508191026,"sku":"4503831","price":90.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5fd66695a68071324f40d91d181dbbb_82f8e0d8-4694-47d0-a3e3-3297a9a48c71.jpg?v=1788692361","url":"https:\/\/voomisupply.com\/products\/iscar-4503831-er32-collet-0-125-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
