It provides a rigid, high-torque connection between the machine spindle and cutting tool, reducing vibration and maintaining concentricity during milling operations. The chuck features internal coolant-through capability, directing coolant fluid directly to the cutting zone for improved chip evacuation and tool life. At 2.442 pounds, it is built for the demands of production machining environments. Installation and tool changes are performed by qualified CNC machinists or toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis milling chuck is suited for vertical and horizontal CNC machining centers equipped with a CAT40 spindle interface. The internal coolant-through design makes it well matched for deep-pocket milling, high-feed roughing, and applications where flood coolant alone cannot adequately reach the cutting edge. It is appropriate for both job shop and production floor use where consistent tool holding performance is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n\u003cli\u003eInternal coolant-through design delivers coolant directly to the cutting tool\u003c\/li\u003e\n\u003cli\u003eRigid chuck body supports high-torque milling applications\u003c\/li\u003e\n\u003cli\u003eCompact and balanced construction at 2.442 pounds\u003c\/li\u003e\n\u003cli\u003eCompatible with standard CAT40 tooling protocols and retention knobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit toolholder for CNC machining centers with a CAT40 taper spindle interface and internal coolant supply capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician. Always power down and lock out the machine spindle before mounting or removing any toolholder. Verify that the spindle taper and chuck taper are clean and free of chips or debris before seating. Confirm that the machine coolant-through system pressure is compatible with the chuck before activating internal coolant flow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.442 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: EMUGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6494.401406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":51979999838514,"sku":"6494.401406","price":775.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fd6b3bb56921b668c3789e496242601.jpg?v=1789981229","url":"https:\/\/voomisupply.com\/products\/emuge-6494-401406-milling-chuck-cat40-internal-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
