It accepts a nominal collet size of 2.00mm (0.078 inches) with a minimum collet capacity of 0.039 inches (1.0mm), allowing it to grip smaller-shank tooling within its clamping range. The collet maintains a Total Indicator Runout (TIR) of 0.01mm, making it suitable for applications where concentricity and repeatability are critical. Machinists and tool room technicians install this collet into an ER20-compatible collet chuck or toolholder as part of a standard workholding setup on CNC or manual spindle equipment.\u003c\/p\u003e\u003cp\u003eThis collet fits standard ER20 collet chucks used across a wide range of benchtop and production CNC mills, routers, and engraving machines. The ER20 series is one of the most commonly used collet standards in light-to-medium duty machining environments, including job shops, production cells, and toolroom operations. It is appropriate for holding end mills, drills, reamers, and other round-shank cutting tools within the stated capacity range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER20 series collet with 2.00mm nominal collet size\u003c\/li\u003e\n\u003cli\u003e0.01mm TIR for consistent concentricity and reduced runout\u003c\/li\u003e\n\u003cli\u003eMinimum collet capacity of 0.039 inches (1.0mm) to accommodate smaller shanks\u003c\/li\u003e\n\u003cli\u003eCompatible with standard ER20 collet chucks and toolholders\u003c\/li\u003e\n\u003cli\u003ePrecision-ground construction for repeatable toolholding in production and toolroom use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ER20 series collet for use with any ER20-compatible collet chuck or toolholder.

The spindle or toolholder assembly should be fully de-energized and at rest before inserting or removing collets. Do not exceed the stated clamping range; using a collet outside its listed capacity can result in inadequate grip and tool pullout. Follow machine tool manufacturer torque guidelines for collet nut tightening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Collet Size\u003c\/strong\u003e: 2.00mm (0.078 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.039 inches (1.0mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01mm\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: 587473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750323093810,"sku":"587473","price":34.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26b7669c996ed0709c415a9270da7e0b.jpg?v=1788914794","url":"https:\/\/voomisupply.com\/products\/accupro-587473-er20-collet-2-00mm-0-078-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
