The arbor features a 5\/8-inch straight shank and a JT3 tapered mount, providing a secure mechanical interface between the chuck and the spindle. Weighing 0.4 pounds, this compact arbor is suited for use in drill presses, milling machines, and similar rotating equipment. Machinists, tool-and-die workers, and maintenance technicians install this type of arbor when mounting or replacing drill chucks on equipment with compatible spindle bores.\u003c\/p\u003e\u003cp\u003eThis arbor is used in machine shop and industrial maintenance environments where a JT3 chuck mount is required. It is appropriate for light to medium drilling operations on drill presses or vertical mills equipped with a straight-shank spindle accepting a 5\/8-inch arbor. The JT3 taper mount is a widely used standard in drilling equipment, making this arbor a common replacement or spare component in shops running multiple machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eJT3 (Jacobs Taper No. 3) mount for direct chuck installation\u003c\/li\u003e\n\u003cli\u003e5\/8-inch straight shank diameter for spindle compatibility\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight design at 0.4 pounds\u003c\/li\u003e\n\u003cli\u003eTapered mount provides secure, self-locking chuck seating\u003c\/li\u003e\n\u003cli\u003eSingle-piece arbor construction for reliable torque transfer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with JT3 drill chucks on machines equipped with a 5\/8-inch straight-shank spindle bore.

Power down and lock out the machine before installing or removing the arbor. Press the JT3 taper firmly and evenly into the chuck to ensure full seating before mounting the assembly in the spindle. Inspect both mating tapered surfaces for burrs or debris prior to assembly, as surface contamination can prevent proper seating and cause runout.\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: JT3 (Jacobs Taper No. 3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: ECIL583000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727141306674,"sku":"ECIL583000MSC","price":29.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7540204fb765d160f6579e7ccf733595.jpg?v=1788673937","url":"https:\/\/voomisupply.com\/products\/accupro-ecil583000msc-taper-drill-chuck-arbor-jt3","provider":"Voomi Supply","version":"1.0","type":"link"}
