The outside taper is CAT 40 for direct spindle mounting, while the inside taper accepts MT4 tooling such as drill chucks, end mill holders, and live centers. With a 3.75-inch projection and bore diameters of 1.231 inches and 1.889 inches, this adapter provides a rigid interface between two common taper standards. It is installed by licensed machinists and CNC setup technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for shops running CAT 40 spindle machines that need to use MT4-shank tooling without re-tooling the entire spindle line. Typical applications include drilling, reaming, and light milling operations where MT4 tooling is already on hand. The adapter weighs 2.646 pounds, indicating a solid steel construction appropriate for the rotational loads and vibration inherent in machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT 40 outside taper for direct mounting to CAT 40 spindles\u003c\/li\u003e\n  \u003cli\u003eMT4 inside taper accepts standard Morse Taper 4 tooling\u003c\/li\u003e\n  \u003cli\u003e3.75-inch projection from spindle face\u003c\/li\u003e\n  \u003cli\u003eBore diameters of 1.231 inches and 1.889 inches\u003c\/li\u003e\n  \u003cli\u003eSolid construction at 2.646 pounds for rigid tool support\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style adapter for CNC machining centers and vertical mills equipped with CAT 40 spindles requiring MT4 inside taper tooling compatibility.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before installing or removing any taper adapter. Ensure both the CAT 40 and MT4 taper surfaces are clean and free of chips, burrs, or coolant residue before seating the adapter. Follow the machine manufacturer guidelines for retention knob torque and draw bar engagement on CAT 40 tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Connection\u003c\/strong\u003e: CAT 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Connection\u003c\/strong\u003e: MT4 (Morse Taper 4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Small)\u003c\/strong\u003e: 1.231 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Large)\u003c\/strong\u003e: 1.889 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.646 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51988371407154,"sku":"22617","price":167.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a8aecfeed31dd48e5d35f51df7d338b_c72a8b0d-ba31-497c-837b-cfa53172e1f9.jpg?v=1789987520","url":"https:\/\/voomisupply.com\/products\/techniks-22617-cat-40-to-mt4-morse-taper-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
