It provides a rigid, concentric connection between a CAT40 spindle and a JT2 drill chuck, making it a practical tooling solution for machining centers and CNC mills equipped with CAT40 spindles. The adapter has a 1.61-inch projection and a 1.181-inch hole diameter. Coolant-through capability is not supported. Machinists and toolroom technicians install this adapter when adding a JT2 drill chuck to a CAT40 machine spindle.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for use on vertical and horizontal machining centers with CAT40 spindle interfaces. It is commonly used in job shops, production facilities, and toolrooms where drill chucks with JT2 mounts need to be run on CAT40 machines. The adapter accepts standard JT2 taper drill chucks and seats into a CAT40 spindle using the standard V-flange retention system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 outside taper seats directly into CAT40 spindle interfaces\u003c\/li\u003e\n\u003cli\u003eJT2 inside taper accepts standard Jacobs Taper 2 drill chucks\u003c\/li\u003e\n\u003cli\u003e1.61-inch projection provides clearance for chuck installation\u003c\/li\u003e\n\u003cli\u003e1.181-inch hole diameter matches JT2 taper specifications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through, simplifying setup on non-coolant-through spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40 spindle machines and JT2 taper drill chucks.

Power down and lock out the machine spindle before installing or removing any tooling adapter. Seat the CAT40 taper fully into the spindle and engage the drawbar to the correct retention force using a torque wrench per the machine tool manufacturer specifications. Press or drive the JT2 chuck onto the adapter taper using the appropriate arbor press procedure before mounting the assembly in the spindle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Connection Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Connection Size\u003c\/strong\u003e: JT2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.61 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1.181 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 778858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752039186738,"sku":"778858","price":109.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d49a82d03fbb3aa46d8f61ab4981795.jpg?v=1788925441","url":"https:\/\/voomisupply.com\/products\/accupro-778858-cat40-to-jt2-taper-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
