It accepts a 3\/4 inch bore and delivers a total indicator reading (TIR) of 0.000010 inch, making it well-suited for high-speed, tight-tolerance work. The chuck supports through-coolant delivery and is balanced to 25000 RPM. At 4.25 inches overall length and 2.36 inches body diameter, it fits standard CAT40 spindle interfaces. Licensed machinists and toolroom technicians are the primary installers of this style of holder in CNC machining center environments.\u003c\/p\u003e\u003cp\u003eThis hydraulic chuck is used in CNC vertical and horizontal machining centers equipped with CAT40 spindles. It is appropriate for high-speed finishing operations where runout control is critical, such as reaming, boring, and precision end milling. The through-coolant feature supports chip evacuation and tool cooling at elevated spindle speeds.

Power down and lock out the spindle drive before mounting or removing the tool holder. Use a calibrated torque wrench and follow the machine tool manufacturer guidelines for drawbar retention force. Verify runout with a test indicator after seating to confirm TIR is within specification before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 38.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 51.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 2.3622 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 25000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.000010 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\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: 1527334\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743894044978,"sku":"1527334","price":357.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/275e3679e3699ea8b821f32b3cc4945a.jpg?v=1788851000","url":"https:\/\/voomisupply.com\/products\/accupro-1527334-hydraulic-chuck-cat40-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
