The ER25 collet standard is one of the most widely used toolholding formats in precision machining, offering a strong radial grip and consistent concentricity for rotating tool applications. This collet is rated to 1000 units of clamping pressure and weighs 0.7 pounds. It is installed by machinists and toolroom technicians performing setup, changeover, or tooling maintenance on compatible ER25 chuck systems.\u003c\/p\u003e\u003cp\u003eThe ACCUPRO 588350 is suited for use in machine shops running CNC or manual spindle equipment where ER25 toolholding is the established standard. Typical applications include end mill holding, drill chuck setups, and reamer or tap extensions in both production and job-shop environments. The 12 mm bore size accommodates round-shank cutting tools with a 12 mm shank diameter. This collet fits residential and commercial machine shop settings where repeatable toolholding accuracy is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet series for broad compatibility with ER25-standard chuck bodies\u003c\/li\u003e\n\u003cli\u003e12 mm bore accommodates 12 mm shank diameter tooling\u003c\/li\u003e\n\u003cli\u003e1000-rated clamping pressure for secure tool retention during rotation\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 0.7 pounds for easy handling and quick changeover\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit sold individually, no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for toolholding chucks built to the ER25 collet standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER collets are installed and removed by machinists using an appropriate ER25 collet nut and spanner wrench sized for the chuck body. Always power down and lock out the spindle before changing collets. Inspect the collet bore and chuck taper for chips or debris before seating the collet, as contamination will affect runout and tool retention. Follow machine manufacturer torque guidance for the collet nut — do not overtighten, as this can distort the collet bore and reduce grip accuracy.\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 Bore Size\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Pressure Rating\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\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: 588350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728384459058,"sku":"588350","price":58.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f759144e8aa90d9caac5214c9aae277a.jpg?v=1788690807","url":"https:\/\/voomisupply.com\/products\/accupro-588350-er25-collet-12-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
