It features a CAT40 taper shank and accepts ER25 collets across a capacity range of 0.039 to 0.629 inches. The chuck projects 2.5 inches from the spindle face and holds a total indicator runout (TIR) of 0.0002 inches, making it suitable for tight-tolerance work. Through-spindle and DIN flange coolant delivery is supported. The collet nut diameter is 1.65 inches. This tool is balanced to 30,000 RPM, supporting high-speed spindle applications. Licensed machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis chuck is used in CAT40-spindle vertical and horizontal machining centers running ER25 tooling. Typical applications include milling, drilling, reaming, and tapping in production and job-shop environments. The through-coolant design directs cutting fluid directly to the tool tip, reducing heat and extending tool life during deep-cavity or long-reach operations. It is appropriate for both light finishing passes and moderate material-removal operations where runout control is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet system with capacity range of 0.039 to 0.629 inches\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on standard machining centers\u003c\/li\u003e\n\u003cli\u003e0.0002 inches TIR for high-precision, low-runout toolholding\u003c\/li\u003e\n\u003cli\u003e2.5 inches projection from spindle face for reach flexibility\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant delivery to the cutting edge\u003c\/li\u003e\n\u003cli\u003eBalanced to 30,000 RPM for high-speed spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40-spindle machining centers that accept ER25 collets.

Power down and lock out the spindle drive before mounting or removing the chuck. Use the correct CAT40 pull stud and torque the drawbar according to the machine manufacturer specifications. Verify TIR with a dial indicator after seating to confirm proper collet and chuck engagement before running the spindle.\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\u003eProjection\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 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\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: 775650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67581907239218,"sku":"775650","price":166.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/498a82a6a447b9118a62cf682f446de9.jpg?v=1790409917","url":"https:\/\/voomisupply.com\/products\/accupro-775650-er25-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
