It accepts ER25 collets with a capacity range of 0.039 to 0.629 inches and delivers a total indicator runout (TIR) of 0.0002 inches, making it suitable for tight-tolerance milling, drilling, and reaming operations. The chuck features a 6-inch projection and is balanced to 30,000 RPM for high-speed spindle applications. Licensed machinists and CNC operators install this chuck as part of the tool assembly process on CAT40-spindle machines.\u003c\/p\u003e\u003cp\u003eThis collet chuck is intended for use on machining centers equipped with a CAT40 spindle interface. The 6-inch projection provides clearance for deep-cavity work or fixtures that require additional reach. Through-spindle and DIN flange coolant delivery is supported, allowing cutting fluid to reach the tool tip directly for improved chip evacuation and tool life in high-production environments. The 1.65-inch collet nut diameter is standard for ER25 tooling systems. This chuck suits both production shops and job shops running high-speed machining cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet system with 0.039 to 0.629 inches capacity range\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for compatibility with CAT40-spindle machining centers\u003c\/li\u003e\n\u003cli\u003e0.0002 inches TIR for precise, repeatable tool holding\u003c\/li\u003e\n\u003cli\u003e6-inch projection for extended reach in deep-cavity applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable via through-spindle and DIN flange coolant types\u003c\/li\u003e\n\u003cli\u003eBalanced to 30,000 RPM for high-speed machining operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER25 collets on machining centers equipped with a CAT40 spindle interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists or CNC technicians. Spindle power must be locked out and the machine brought to a complete stop before mounting or removing the chuck. Use the appropriate ER25 collet nut wrench and spanner to achieve proper clamping torque per the collet manufacturer's guidelines. Inspect the taper shank and spindle bore for contamination or damage before seating the chuck.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.629 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle and DIN Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 30,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 775654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727238103346,"sku":"775654","price":173.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72b053658bbf1fd49e98c8634e6f333f.jpg?v=1788675206","url":"https:\/\/voomisupply.com\/products\/accupro-775654-er25-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
