The arbor serves as the mechanical interface between the chuck and the spindle, transmitting rotational force and maintaining concentric alignment during drilling operations. Weighing 3.3125 pounds, it is built for use in drill presses, lathes, milling machines, and other machine tools equipped with a 5MT spindle bore. Machinists, tool and die technicians, and maintenance mechanics are the primary installers of this type of arbor.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for industrial and shop environments where a JT3 chuck must be mounted to a machine with a No. 5 Morse Taper spindle. Typical applications include floor-standing drill presses, metalworking lathes, and heavy-duty machine tool setups that require a secure, repeatable chuck-to-spindle connection. It is appropriate for both production and maintenance contexts where chuck interchange or replacement is part of routine machine servicing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJT3 (Jacobs Taper 3) mount accepts standard JT3 drill chucks\u003c\/li\u003e\n  \u003cli\u003eNo. 5 Morse Taper shank fits machines with a 5MT spindle bore\u003c\/li\u003e\n  \u003cli\u003eTapered shank design provides self-holding friction fit in the spindle\u003c\/li\u003e\n  \u003cli\u003eEnables direct chuck-to-spindle mounting without additional adapters\u003c\/li\u003e\n  \u003cli\u003eWeighs 3.3125 pounds, indicating a robust, heavy-duty construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style arbor for use with JT3 drill chucks on machine tools equipped with a No. 5 Morse Taper spindle socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified machine tool technicians. Before installing or removing the arbor, power down the machine and confirm the spindle has come to a complete stop. The 5MT shank is driven into the spindle bore using a soft mallet or arbor press to seat the taper; removal typically requires a drift key inserted through the spindle drift slot. Ensure the taper surfaces are clean and free of burrs or oil before seating to maintain concentricity and prevent fretting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Taper Size\u003c\/strong\u003e: JT3 (Jacobs Taper 3)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Size\u003c\/strong\u003e: 5MT (No. 5 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.3125 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: JACOBS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7327N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67912548942130,"sku":"7327N","price":178.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d5efddc4db8563063025339b6dccc61.jpg?v=1791235833","url":"https:\/\/voomisupply.com\/products\/jacobs-7327n-drill-chuck-arbor-jt3-mount-5mt-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
