The arbor serves as the mechanical interface between the chuck and the machine spindle, transmitting rotational force while maintaining concentricity during drilling operations. It is a standard shop consumable used on milling machines and drill presses equipped with an R8 spindle taper. Machinists, tool and die workers, and general machine shop technicians install this component when mounting or replacing drill chucks on compatible equipment. Weighing 0.9 pounds, it is a compact, solid arbor built for repeated installation and removal cycles.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for benchtop and knee-style milling machines with R8 spindle tapers, which are common in small to mid-size machine shops and vocational training environments. The JT2 mount accommodates a wide range of standard drill chucks with a matching Jacobs Taper 2 socket. It is typically used in drilling, reaming, and light boring operations where a secure, repeatable chuck mount is required. One arbor ships per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJT2 Jacobs Taper mount accepts standard JT2 drill chucks\u003c\/li\u003e\n  \u003cli\u003eR8 shank taper fits R8 spindle machines without adapters\u003c\/li\u003e\n  \u003cli\u003eTapered shank and mount provide self-centering alignment for concentricity\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.9 pounds for easy bench handling\u003c\/li\u003e\n  \u003cli\u003eSingle-piece arbor construction for rigid chuck retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit arbor for milling machines and drill presses with an R8 spindle taper, paired with drill chucks that use a JT2 Jacobs Taper socket interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or machine tool technician. Power down and lock out the machine spindle before seating or removing the arbor. The R8 shank is secured by the machine drawbar; ensure the drawbar is fully tightened before operating the spindle. Never strike the chuck or arbor directly with a steel hammer when removing — use a soft mallet or the machine drawbar release mechanism to avoid damage to the taper surfaces.\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: JT2 (Jacobs Taper 2)\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: R8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 222-772\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698944672050,"sku":"222-772","price":30.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a03400ab7c3e8bcacc09478a5eed136.jpg?v=1788370185","url":"https:\/\/voomisupply.com\/products\/value-collection-222-772-taper-drill-chuck-arbor-jt2-r8","provider":"Voomi Supply","version":"1.0","type":"link"}
