It accepts a nominal collet size of 0.236 inches (6.00mm) with a minimum collet capacity of 0.216 inches (5.5mm), giving the tool a usable clamping range across that span. The collet holds a Total Indicator Runout (TIR) of 0.02mm, making it suitable for close-tolerance work where concentricity directly affects finish and tool life. Licensed machinists and CNC setup technicians are the primary installers of this type of tooling component.\u003c\/p\u003e\u003cp\u003eER11 collets are used in compact spindle noses, collet chucks, and toolholders that accept the ER11 standard. This size range is common in high-speed engraving spindles, micro-milling machines, and benchtop CNC routers where smaller shank tooling is standard. The 587670 fits into any ER11-compatible chuck body and is appropriate for both production and prototype machining environments requiring consistent tool grip and repeatable runout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER11 collet series for use with ER11-compatible chuck bodies\u003c\/li\u003e\n\u003cli\u003e0.236 inch (6.00mm) nominal collet size with a 0.216 inch (5.5mm) minimum clamping capacity\u003c\/li\u003e\n\u003cli\u003e0.02mm TIR for precise concentricity and reduced tool runout\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging, sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or spare for any ER11-standard collet chuck or toolholder accepting the ER11 collet series at the 6.00mm nominal size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER11 collets are installed by machinists or CNC technicians using a properly sized ER11 collet nut and spanner wrench. The spindle or chuck body should be fully stopped and de-energized before collet changes. Do not force or hammer the collet into the chuck; it should seat smoothly by hand before the nut is torqued. Inspect collet bore and chuck taper for chips or damage before each installation to protect TIR performance.\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\u003eNominal Collet Size\u003c\/strong\u003e: 0.236 inches (6.00mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.216 inches (5.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.02mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 587670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738312638770,"sku":"587670","price":28.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6b108d392fd96e4213701a1f2bca69b.jpg?v=1788798120","url":"https:\/\/voomisupply.com\/products\/accupro-587670-er11-collet-0-236-inch-6-00mm","provider":"Voomi Supply","version":"1.0","type":"link"}
