The adapter features a 1.77-inch projection and a 1.57-inch hole diameter, with through-coolant capability to support high-pressure coolant delivery directly to the cutting tool. This type of adapter is installed by machinists and tool crib technicians to allow Morse taper tooling to run in CAT50 spindles without requiring a full toolholder change. The through-coolant passage helps extend tool life and improve chip evacuation during drilling and boring operations.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for production machining environments where CAT50 spindle machines need to accept 3MT shank tooling such as drill chucks, reamers, and boring heads. It is a common fitment in job shops and manufacturing facilities running vertical or horizontal machining centers with CAT50 spindle interfaces. The 1.77-inch projection keeps the tool gauge length predictable for setup. Through-coolant support makes it compatible with machines equipped with high-pressure coolant systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 outside taper interfaces directly with CAT50 spindles\u003c\/li\u003e\n  \u003cli\u003e3MT inside taper accepts standard Morse taper shank tooling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant passage supports high-pressure coolant delivery to the cutting edge\u003c\/li\u003e\n  \u003cli\u003e1.77-inch projection for consistent gauge length at setup\u003c\/li\u003e\n  \u003cli\u003e1.57-inch hole diameter accommodates standard 3MT tooling shanks\u003c\/li\u003e\n  \u003cli\u003eWeighs 1 pound for easy handling during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement adapter for CAT50 spindle machining centers requiring 3MT inside taper tooling interfaces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool crib personnel. Power down and lock out the machining center spindle before installing or removing the adapter. Use the correct retention knob and drawbar torque specifications provided by the machine manufacturer for CAT50 tooling. Inspect the taper bore and the adapter shank for nicks, burrs, or contamination before seating to ensure full taper contact and runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Connection Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Connection Size\u003c\/strong\u003e: 3MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Style\u003c\/strong\u003e: Through Coolant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 778938\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728274587954,"sku":"778938","price":173.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95ad448f3e585cc56291ab403f14dc4d.jpg?v=1788690199","url":"https:\/\/voomisupply.com\/products\/accupro-778938-cat50-to-3mt-taper-adapter-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
