This collet features through-coolant capability, allowing coolant to be directed to the cutting zone for improved chip evacuation and tool life. It holds a Total Indicator Runout (TIR) of 0.0050 mm, providing the concentricity required for precision drilling, reaming, and milling operations. Machinists and CNC operators rely on tight-tolerance collets like this one to maintain part accuracy across production runs.\u003c\/p\u003e\u003cp\u003eThis collet is suited for light-duty precision machining applications in job shops, production facilities, and toolrooms. The ER11 series is one of the most widely used collet standards in small-spindle CNC work, commonly found in benchtop machining centers, Swiss-style lathes, and engraving machines. The 2 mm bore size is appropriate for small-diameter end mills, drill bits, reamers, and other round-shank cutting tools used in precision component manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER11 collet series for compatibility with standard ER11 collet chucks\u003c\/li\u003e\n\u003cli\u003e2 mm bore size for small-diameter round-shank tooling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs coolant to the cutting zone\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0050 mm for high concentricity and precision runout performance\u003c\/li\u003e\n\u003cli\u003eCompact ER11 form factor suited for high-speed spindle applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard ER11 collet chucks and compatible spindle toolholders accepting the ER11 collet series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or CNC technician with the spindle fully stopped and the machine in a safe, locked-out state. Use a proper ER collet nut wrench to torque the collet nut  -  do not use improvised tools that can damage the collet or chuck threads. Inspect the collet bore and seating surfaces for contamination or wear before each use, as debris will directly affect runout. Confirm through-coolant passages are clear and that the collet chuck is rated for through-coolant operation before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2 mm\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: 0.0050 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 04211-02.0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51971560309042,"sku":"04211-02.0","price":50.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6e670015579a48517661d3bb2d5b18a_93737cdc-c1c0-498c-8d75-8ce9fdf9f8ed.jpg?v=1789958718","url":"https:\/\/voomisupply.com\/products\/techniks-04211-02-0-er11-collet-2-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
