ER collets provide a secure, concentric grip on cutting tools and workholding shanks, transmitting rotational force with minimal runout. This collet measures 1.9 inches in height with a 1.2-inch width and length, and weighs approximately 0.1 pounds. It is a single-piece unit sold individually. Machinists and CNC operators install ER collets as standard toolholding components across a wide range of production and job-shop environments.\u003c\/p\u003e\u003cp\u003eER25 collets are widely used in light to medium-duty machining applications where a compact, standardized collet chuck system is required. The 0.375-inch bore size accommodates tooling with a 3\/8-inch shank diameter, including end mills, drills, reamers, and taps. This collet is suited for both manual and CNC-controlled spindles equipped with ER25-compatible chucks found in vertical machining centers, lathes with live tooling, and router spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet series for use with ER25-compatible chucks and toolholders\u003c\/li\u003e\n\u003cli\u003e0.375-inch (3\/8-inch) bore for standard shank tooling\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 1.9 inches tall, 1.2 inches wide and long\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.1 pounds for minimal spindle load contribution\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order beyond one unit\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 27112800 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER25-series collet chucks and toolholding systems that accept standard ER25 collets with a 3\/8-inch shank bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER collets are installed by a machinist or CNC technician. Power down and lock out the machine spindle before changing collets. Insert the collet into the ER25 chuck nut before threading onto the chuck body to avoid damaging the collet retaining groove. Use a calibrated torque wrench and the chuck manufacturer's specified tightening procedure to secure the nut. Inspect the collet seating surfaces for chips or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Fractional)\u003c\/strong\u003e: 3\/8 inch\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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 784956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748513382706,"sku":"784956","price":33.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ac288a3de670e75d3500f298ad9207c.jpg?v=1788894690","url":"https:\/\/voomisupply.com\/products\/accupro-784956-er25-collet-0-375-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
