Built to accept standard milling cutters, this arbor transmits torque from the machine spindle to the cutter through a precision-ground shank. The overall length runs 37.38 inches, and the shank diameter measures 2.75 inches, making it suitable for heavy-duty material removal on large-format vertical and horizontal knee mills and bed mills. It ships complete with arbor spacers and two running bushings, reducing the need to source additional components separately.\u003c\/p\u003e\n\u003cp\u003eThis arbor is intended for use in machine shop environments where NMTB50 spindle tooling is standard. It fits knee mills and horizontal milling machines equipped with NMTB50 spindle tapers. The shoulder-to-nut length of 30 inches accommodates wide cutter stacks, and the included 2-3\/4-inch diameter bushings at 4-1\/4-inch length help support the arbor outboard for stable, chatter-free cutting. Typical installers are machinists and tool-and-die professionals working in job shops, production facilities, and maintenance departments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStyle B arbor design with NMTB50 taper shank for positive spindle engagement\u003c\/li\u003e\n  \u003cli\u003e1.5-inch arbor diameter accommodates a wide range of standard milling cutters\u003c\/li\u003e\n  \u003cli\u003eOverall length of 37.38 inches with a 30-inch shoulder-to-nut working length\u003c\/li\u003e\n  \u003cli\u003eIncludes arbor spacers and two running bushings (2-3\/4-inch diameter, 4-1\/4-inch length)\u003c\/li\u003e\n  \u003cli\u003eDrawbar thread size 1-8 for secure spindle retention\u003c\/li\u003e\n  \u003cli\u003e2.75-inch shank diameter for rigid taper-to-spindle interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with milling machines equipped with an NMTB50 taper spindle and a 1-8 drawbar thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine fully powered down and the spindle locked before seating or removing the arbor. The drawbar must be tightened to secure the taper shank before any cutting operation begins. Inspect the taper bore and arbor shank for debris or damage prior to each installation. Outboard support via the included running bushings and the machine overarm should be set up before running the spindle under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Style\u003c\/strong\u003e: Style B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: NMTB50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 37.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder to Nut Length\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrawbar Thread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Diameter\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Length\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Bushings\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Arbor Spacer, Running Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 75 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 219-9556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702996238642,"sku":"219-9556","price":947.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/395c4dc93a381de62d2b1ef3733766a9_540497e8-a8ba-4b78-824e-32181f4f72c1.jpg?v=1788414246","url":"https:\/\/voomisupply.com\/products\/value-collection-219-9556-milling-machine-arbor-style-b","provider":"Voomi Supply","version":"1.0","type":"link"}
