With a collet size of 0.236 inches (6.00 mm) and a total indicated runout (TIR) of 0.01 mm, this collet delivers the concentricity required for accurate cutting tool retention. The minimum collet capacity is 0.196 inches (5.0 mm), giving the collet a usable clamping range suitable for a variety of shank diameters. Machinists and toolroom technicians working with ER16-compatible spindles and chucks will find this collet a direct-fit solution for maintaining tight tolerances on rotating tools.\u003c\/p\u003e\n\u003cp\u003eThe 587312 is suited for use in ER16 collet chucks mounted on CNC machining centers, manual mills, lathes, and high-speed spindles where consistent grip and minimal runout are critical. It is appropriate for light to medium cutting operations using end mills, drills, reamers, and other straight-shank tooling within the collet capacity range. This collet is a standard single-piece unit packaged individually and is well suited for production shops, toolrooms, and maintenance environments that rely on the ER16 standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series — compatible with standard ER16 collet chucks and holders\u003c\/li\u003e\n  \u003cli\u003e0.236 inch (6.00 mm) collet size with 0.196 inch (5.0 mm) minimum clamping capacity\u003c\/li\u003e\n  \u003cli\u003e0.01 mm TIR for high concentricity and reduced tool runout\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual replacement or inventory building\u003c\/li\u003e\n  \u003cli\u003eWeighs 1 pound — compact and lightweight for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard ER16 collet chucks and toolholding systems accepting the ER16 collet series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before installing or removing the collet, ensure the spindle is fully stopped and the machine is powered down or in a safe lockout state. Seat the collet fully into the ER16 chuck before threading the nut to avoid damage to the collet taper. Use a properly sized ER collet wrench and chuck wrench for tightening — do not use makeshift tools that could damage the nut or collet body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 0.236 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.196 inches (5.0 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 587312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51745574519090,"sku":"587312","price":31.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88f2b22b63d597621b2f8bb776e07adc.jpg?v=1788864472","url":"https:\/\/voomisupply.com\/products\/accupro-587312-er16-collet-0-236-inch-precision","provider":"Voomi Supply","version":"1.0","type":"link"}
