It accepts a nominal tool shank diameter of 0.153 inches, with a minimum collet capacity of 0.141 inches, and measures 1.378 inches in overall length. The ER25 collet system is one of the most widely used toolholding standards in precision machining, and this collet is built to deliver consistent grip force and runout accuracy when seated in a compatible ER25 chuck or toolholder. Machinists and CNC operators install this collet as part of standard tool change and setup procedures.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in machining centers, lathes, routers, and grinding machines that accept the ER25 collet system. It is appropriate for light to medium-duty cutting applications in job shop, production, and maintenance machining environments. The 0.153-inch capacity makes it a practical choice for small-diameter end mills, drills, and reamers commonly used in precision metalworking and toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series — compatible with standard ER25 chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003e0.153-inch nominal collet capacity with a 0.141-inch minimum collet capacity\u003c\/li\u003e\n  \u003cli\u003e1.378-inch overall length for consistent projection and fit\u003c\/li\u003e\n  \u003cli\u003eDesigned for repeatable clamping and accurate tool positioning\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during tool changes\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 machine tools equipped with a standard ER25 collet chuck or toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Before inserting the collet, ensure the machine spindle is powered down and at a complete stop. Seat the collet fully into the ER25 nut before threading onto the chuck body — do not tighten the nut with the collet loose or misaligned, as this can damage the collet taper. Inspect the collet bore and chuck taper for chips or contamination before each use to maintain runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.153 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\u003eOverall Length\u003c\/strong\u003e: 1.378 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 784805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733887516978,"sku":"784805","price":56.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86491456d8bfef5616d6fc25d02d908a.jpg?v=1788759754","url":"https:\/\/voomisupply.com\/products\/accupro-784805-er25-collet-0-153-in-1-378-in-oal","provider":"Voomi Supply","version":"1.0","type":"link"}
