This collet holds a nominal tool shank diameter of 0.433 inches (11.00mm) with a minimum collet capacity of 0.393 inches (10.0mm), allowing a small clamping range for secure tool retention. The overall length measures 35.0mm and the collet holds a total indicator runout (TIR) of 0.01mm, making it suitable for applications where concentricity and repeatability are critical to part quality and tool life.\u003c\/p\u003e\u003cp\u003eThis collet is used in machine shops, production environments, and tool rooms where ER25 collet chucks are installed. Typical applications include end milling, drilling, reaming, and tapping operations on CNC or manual spindles. The ER25 system is a widely adopted standard in precision machining, and this collet fits any ER25-compatible chuck or tool holder. It is installed and handled by machinists, toolroom technicians, and CNC setup personnel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet series for use with ER25-compatible chucks and tool holders\u003c\/li\u003e\n\u003cli\u003eNominal collet size of 0.433 inches (11.00mm) with minimum capacity of 0.393 inches (10.0mm)\u003c\/li\u003e\n\u003cli\u003e0.01mm TIR for high concentricity and reduced tool runout\u003c\/li\u003e\n\u003cli\u003e35.0mm overall length suits standard ER25 chuck depths\u003c\/li\u003e\n\u003cli\u003eSingle-piece construction for consistent clamping force across the collet bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER25 series collet chucks and tool holders conforming to the ER25 collet standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the spindle or chuck is fully stopped and locked out before inserting or removing the collet. Clean the collet bore and chuck taper thoroughly before assembly to avoid contamination that can increase runout. Use the appropriate ER25 collet nut and tighten with a calibrated collet wrench to the chuck manufacturer's specified procedure.\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\u003eNominal Collet Size\u003c\/strong\u003e: 0.433 inches (11.00mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.393 inches (10.0mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 35.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01mm\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\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: 587346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731657982258,"sku":"587346","price":34.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfa20dc85cf3b106c672b193a4bb53fd.jpg?v=1788733628","url":"https:\/\/voomisupply.com\/products\/accupro-587346-er25-collet-0-433-inch-11-00mm","provider":"Voomi Supply","version":"1.0","type":"link"}
