It serves as the mechanical interface between the chuck and the spindle, transmitting torque and maintaining concentricity during drilling operations. The arbor features a tapered shank that seats directly into a 1MT spindle bore and a JT1 mount taper at the opposite end for chuck installation. At an overall length of approximately 3.31 inches (84 mm) and a weight of 0.13 pounds, it is a compact, lightweight component suited for benchtop drill presses and light machining equipment.\u003c\/p\u003e\u003cp\u003eThis arbor is appropriate for use in machine shop, maintenance, and light production environments where a JT1 chuck must be mounted to a 1MT spindle. Typical applications include benchtop and floor-standing drill presses, milling machine quills fitted with 1MT bores, and similar light-duty metal or woodworking equipment. Machinists and maintenance technicians install this arbor when setting up or replacing drill chuck assemblies on compatible machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eJT1 Jacobs Taper mount accepts standard JT1 drill chucks\u003c\/li\u003e\n\u003cli\u003eNo. 1 Morse Taper (1MT) shank seats into 1MT spindle bores\u003c\/li\u003e\n\u003cli\u003eOverall length of 3.31 inches (84 mm) for compact fitment\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.13 pounds for easy handling during chuck installation\u003c\/li\u003e\n\u003cli\u003eSingle-piece taper arbor construction for direct chuck-to-spindle connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit taper drill chuck arbor for machines equipped with a No. 1 Morse Taper spindle bore and drill chucks with a JT1 Jacobs Taper mount interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Power down and lock out the machine before seating or removing the arbor. The taper shank should be clean and free of burrs or oil before seating into the spindle bore to ensure proper engagement. Use a drawbar or drift key as appropriate for the spindle design when securing or ejecting the arbor.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: JT1 (Jacobs Taper 1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Size\u003c\/strong\u003e: 1MT (No. 1 Morse Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.31 inches (84 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: EJ01100000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754546921778,"sku":"EJ01100000MSC","price":30.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ab43c83ac302e8196df20a441c237f6.jpg?v=1788946496","url":"https:\/\/voomisupply.com\/products\/accupro-ej01100000msc-taper-drill-chuck-arbor-jt1-1mt","provider":"Voomi Supply","version":"1.0","type":"link"}
