The arbor serves as the mechanical interface between the chuck body and the machine, transmitting torque and maintaining concentricity during drilling operations. It is a precision-fit component used in drill presses, milling machines, and lathes equipped with a 2MT spindle bore. Installation requires no special tooling beyond a standard drift and mallet for seating and removal. Machinists, tool and die technicians, and maintenance mechanics are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for both light-duty and general-purpose drilling applications in shop and production environments. The JT33 mount accepts standard JT33-tang chucks commonly found on benchtop and floor-standing drill presses. The 2MT shank seats directly into any spindle or tailstock bored to the No. 2 Morse Taper standard, making it a common replacement or spare in facilities running multiple machines with that spindle size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJT33 mount taper interfaces with standard Jacobs Taper 33 drill chucks\u003c\/li\u003e\n  \u003cli\u003eNo. 2 Morse Taper shank fits machines with a 2MT spindle bore\u003c\/li\u003e\n  \u003cli\u003eHardened taper surfaces provide positive self-locking seating under load\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.3125 pounds for easy handling and tool changes\u003c\/li\u003e\n  \u003cli\u003eCompatible with drill presses, lathes, and milling machine tailstocks using 2MT spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement arbor for drill press and machine tool setups using a JT33 chuck mount and a No. 2 Morse Taper spindle or tailstock bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance personnel. Clean both the spindle bore and the arbor shank thoroughly before seating to ensure full taper contact and prevent fretting. Drive the arbor firmly into the spindle using a soft-face mallet or arbor press; never use steel hammers directly on the taper. To remove, use the appropriate Morse Taper drift in the spindle drift slot and strike firmly to break the self-locking seat before lowering the chuck assembly.\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: JT33 (Jacobs Taper 33)\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: 2MT (No. 2 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3125 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: 7312N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67910289522994,"sku":"7312N","price":49.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45d0486195cc9a02f5dfce7957f91ed8.jpg?v=1791197199","url":"https:\/\/voomisupply.com\/products\/jacobs-7312n-drill-chuck-arbor-jt33-2mt-morse-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
