It accepts workpieces and cutting tools up to 0.196 inches (5.00 mm) in diameter, with a minimum collet capacity of 0.157 inches (4.00 mm). The collet maintains a total indicator runout (TIR) of 0.01 mm, making it suitable for close-tolerance work where concentricity matters. Machinists and CNC operators install this collet into compatible ER16 collet chucks or tool holders to secure end mills, drills, reamers, and similar rotary cutting tools during machining operations.\u003c\/p\u003e\u003cp\u003eThis collet is used in machine shop environments on CNC mills, manual milling machines, and lathes equipped with ER16-compatible spindle tooling. It is appropriate for both production and job-shop settings where consistent tool runout and repeatable clamping force are required. The ER16 series is a widely adopted collet standard, making this part a practical replacement or additional collet for existing ER16 chuck systems already in service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER16 collet series — fits standard ER16 collet chucks and tool holders\u003c\/li\u003e\n\u003cli\u003eMaximum collet capacity of 0.196 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003eMinimum collet capacity of 0.157 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e0.01 mm TIR for close-tolerance, concentric tool holding\u003c\/li\u003e\n\u003cli\u003eSold individually — quantity of one per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit collet for use with ER16 collet chucks and ER16-compatible tool holders across standard CNC and manual milling platforms.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC tooling technicians. Before changing collets, ensure the machine spindle is fully stopped and all power is off or the machine is in a safe lockout state. The collet seats into the ER16 chuck body and is secured with the retention nut — use the appropriate ER16 spanner wrenches to achieve proper clamping without over-torquing. Inspect the collet bore and chuck taper for chips or debris before seating to avoid compromising runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.196 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.157 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01 mm\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: 587310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732013416754,"sku":"587310","price":30.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f4e26417d3f6e35d9a7cbe666d2b262.jpg?v=1788738110","url":"https:\/\/voomisupply.com\/products\/accupro-587310-er16-collet-0-196-inch-5-00mm","provider":"Voomi Supply","version":"1.0","type":"link"}
