It accepts a 3.00mm tool shank and features through-coolant capability, allowing cutting fluid to pass directly through the collet to the tool tip for improved chip evacuation and thermal management. With a Total Indicator Runout (TIR) of 0.0050mm, this collet delivers the concentricity required for tight-tolerance drilling, reaming, and milling operations. Machinists and CNC service technicians rely on ER11 collets for compact toolholding applications where spindle space is limited.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in any ER11-compatible collet chuck or toolholder used in production machining, toolroom work, and precision manufacturing environments. The 3.00mm clamping diameter makes it appropriate for small-diameter end mills, drills, reamers, and taps commonly used in mold work, medical component machining, and electronics manufacturing. It is installed by machinists and CNC technicians as part of routine tooling changes or spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER11 collet series for use in standard ER11 collet chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003e3.00mm clamping diameter accommodates small-diameter cutting tools\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels cutting fluid directly to the tool tip\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0050mm supports high-precision, tight-tolerance machining\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.08 pounds for minimal spindle load contribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling collet for use in ER11-compatible collet chucks and toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eER11 collets are installed by machinists or CNC technicians and require an ER11 collet nut and compatible chuck body. The spindle must be fully stopped and the machine powered down or placed in a safe lockout state before any toolholder or collet change. Use the appropriate ER collet wrench and chuck spanner to achieve proper seating and clamping force. Inspect the collet bore and chuck taper for contamination or damage before installation to maintain rated TIR performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 3.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0050mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04211-03.0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51966219944242,"sku":"04211-03.0","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6e670015579a48517661d3bb2d5b18a.jpg?v=1789950268","url":"https:\/\/voomisupply.com\/products\/techniks-04211-03-0-er11-collet-3-00mm-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
