It holds workpieces or cutting tools with a capacity of 0.156 inches and a minimum collet capacity of 0.141 inches, making it suitable for close-tolerance passes where runout control is critical. The collet delivers a total indicator runout (TIR) of 0.02 mm, a benchmark that matters in finish machining and tight-tolerance boring work. Machinists and CNC setup technicians are the primary installers. At 0.05 pounds, this collet fits easily into standard ER16-compatible toolholders found on vertical machining centers and CNC routers.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in production and job-shop environments where ER16 toolholding systems are already in place. Typical applications include light milling, engraving, drilling, and tapping with small-diameter cutting tools or workpiece stock up to 0.156 inches. The ER16 series is common on benchtop CNC routers, small vertical machining centers, and multi-axis machines where spindle nose size limits toolholder shank diameter. It is sold individually, allowing technicians to stock specific sizes as needed without purchasing a full set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series for use with ER16-compatible toolholders and nuts\u003c\/li\u003e\n  \u003cli\u003e0.156 inch capacity with a minimum capacity of 0.141 inches for secure gripping range\u003c\/li\u003e\n  \u003cli\u003e0.02 mm TIR for precision runout control in finish and close-tolerance operations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds, minimizing added mass in high-speed spindle applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (quantity of 1) for targeted size replacement or inventory builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for ER16-series toolholding systems.

Power down and lock out the machine spindle before inserting or removing any collet. Seat the collet fully into the ER16 nut before threading the assembly onto the toolholder body to prevent collet damage. Inspect the collet bore and toolholder taper for chips or contamination before tightening to preserve TIR performance.\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 Capacity\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 784879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749234966834,"sku":"784879","price":36.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f3bcfb1fd5338375f910df1e896dd85.jpg?v=1788903448","url":"https:\/\/voomisupply.com\/products\/accupro-784879-er16-collet-0-156-inch-capacity","provider":"Voomi Supply","version":"1.0","type":"link"}
