The arbor serves as the mechanical interface between the chuck and the machine, transmitting torque and maintaining concentricity during drilling operations. With an overall length of approximately 5.91 inches (150 millimeters), this arbor fits standard drill press, lathe, and milling machine spindles equipped with a 3MT socket. Machinists, tool room technicians, and shop maintenance personnel are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis chuck arbor is suited for use in machine shop environments, production drilling setups, and maintenance facilities where a JT5 chuck must be mounted on a 3MT spindle. Typical applications include drill presses, lathes with tailstock drilling setups, and milling machine quills. The arbor is appropriate for both light-duty and general-purpose drilling on a range of workpiece materials. It is sold individually and is a direct replacement or spare component for shops maintaining existing tooling assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJT5 Jacobs Taper mount accepts standard JT5 drill chucks\u003c\/li\u003e\n  \u003cli\u003eNo. 3 Morse Taper (3MT) shank fits 3MT machine spindle sockets\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5.91 inches (150 millimeters) suits common drill press and lathe tailstock clearances\u003c\/li\u003e\n  \u003cli\u003eTapered shank provides self-holding fit in the spindle bore\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction maintains chuck-to-spindle alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement arbor for drill presses, lathe tailstocks, and milling machine quills equipped with a No. 3 Morse Taper spindle socket and a JT5 Jacobs Taper chuck mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified tool room personnel. Before mounting or removing the arbor, ensure the machine is fully powered down and the spindle is locked. Clean the 3MT spindle socket and the arbor shank of any chips, oil, or debris before seating to ensure proper self-holding contact. Use a drift key and a soft mallet to drive the arbor free from the spindle socket during removal — do not pry against the chuck body.\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: JT5 (Jacobs Taper 5)\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: 3MT (No. 3 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.91 inches (150 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.57 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EJ03500000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735176642866,"sku":"EJ03500000MSC","price":39.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/befaedbd941d1129a95333a3e034031c.jpg?v=1788770063","url":"https:\/\/voomisupply.com\/products\/accupro-ej03500000msc-taper-drill-chuck-arbor-jt5-3mt","provider":"Voomi Supply","version":"1.0","type":"link"}
