The arbor serves as the mechanical interface between the drill chuck and the spindle, transmitting rotational force and maintaining accurate chuck alignment during drilling operations. Weighing 1.375 pounds, it is a solid, direct-fit component used by machinists and toolroom technicians working on drill presses, lathes, and milling machines equipped with a 4MT spindle bore.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for industrial and shop environments where a JT33 chuck must be mounted to a 4MT spindle. Common applications include drill press setups, tailstock chuck installations on metalworking lathes, and similar machine tool configurations requiring a reliable taper-to-taper connection. It is a standard component in toolroom maintenance and machine setup work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJT33 (Jacobs Taper No. 33) mount end accepts compatible JT33 drill chucks\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse Taper (4MT) shank fits machine spindles with a 4MT bore\u003c\/li\u003e\n  \u003cli\u003eTaper-to-taper design provides secure, self-holding chuck and spindle connection\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece arbor construction for rigid chuck-to-spindle alignment\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 27112800 for streamlined procurement classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit arbor for drill chucks with a JT33 mount, used in machine spindles or tailstocks with a No. 4 Morse Taper (4MT) bore.

Power down and lock out the machine before seating or removing the arbor. Clean both the spindle bore and the arbor shank thoroughly before insertion to ensure full taper contact and prevent fretting. Use a drift and mallet only through the spindle drift slot to remove the arbor  -  never apply side force to the chuck body during removal.\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 No. 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: 4MT (No. 4 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.375 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: 7325DN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67906031092018,"sku":"7325DN","price":94.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1ffd4e2657e01719b4db071a62acad7.jpg?v=1791163279","url":"https:\/\/voomisupply.com\/products\/jacobs-7325dn-drill-chuck-arbor-jt33-mount-4mt-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
