The arbor features a 0.75-inch straight shank diameter and a shank length of 2.5 inches, providing a rigid, concentric interface between the chuck and the machine spindle. Weighing 0.18 pounds, this compact adapter is suited for precision drilling setups where a secure, repeatable chuck mount is required. Machinists and tool-room technicians rely on this type of arbor to mount and swap drill chucks quickly without sacrificing runout performance.\u003c\/p\u003e\u003cp\u003eThis arbor is used in drilling and light milling applications on bench drill presses, radial arm drills, and similar machine tools that accept a straight-shank tool holder. It is appropriate for both production shop and maintenance environments where JT1-mount drill chucks are in regular use. The straight shank design allows direct clamping in a standard collet, end-mill holder, or drill-press chuck of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eJT1 Jacobs Taper mount provides a positive, self-locking chuck interface\u003c\/li\u003e\n\u003cli\u003eStraight shank type for direct clamping in compatible tool holders\u003c\/li\u003e\n\u003cli\u003e0.75-inch shank diameter fits standard drill press and machining center holders\u003c\/li\u003e\n\u003cli\u003e2.5-inch shank length offers adequate reach for most bench and floor drill press setups\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.18 pounds, minimizing added spindle load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade arbor for drill chucks with a JT1 Jacobs Taper mount bore, used on drill presses and machine tools that accept a straight-shank tool holder of the appropriate diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or tool-room technicians. Power down and de-energize the machine before mounting or removing any chuck arbor. Press or drive the arbor into the chuck taper with a dedicated arbor press rather than striking the chuck body directly to avoid damage to the taper seat. Verify shank clamp force with the machine manufacturer's specifications before resuming operation.\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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: ECIL121000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754223075634,"sku":"ECIL121000MSC","price":26.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37a928b6eef28d28a49ffa6986f1057a.jpg?v=1788943967","url":"https:\/\/voomisupply.com\/products\/accupro-ecil121000msc-taper-drill-chuck-arbor-jt1","provider":"Voomi Supply","version":"1.0","type":"link"}
