The arbor accepts tooling at a 1.25-inch diameter and measures 196 millimeters (7.717 inches) overall length. The stub style keeps the cutting tool close to the spindle nose, reducing overhang and improving rigidity during milling operations. Machinists and tool and die technicians install this arbor when mounting shell end mills, facing cutters, or similar tooling on R8-compatible machines. Weighing 3.18 pounds, this is a solid, production-grade arbor suitable for job shop and light manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis arbor is intended for use with vertical knee mills, bed mills, and similar machine tools that accept an R8 taper spindle. The stub configuration is the preferred choice when minimal tool stick-out is needed for face milling, slotting, or peripheral milling operations. The 2-inch shoulder-to-nut length accommodates standard arbor spacers and collars. This part is suited for manual and CNC-converted knee mills commonly found in machine shops, maintenance departments, and vocational training facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStub arbor style minimizes overhang for improved rigidity and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eR8 taper shank for direct mounting in R8-spindle vertical mills\u003c\/li\u003e\n  \u003cli\u003e1.25-inch arbor diameter accommodates a wide range of shell end mills and facing cutters\u003c\/li\u003e\n  \u003cli\u003e196 mm (7.717 inches) overall length provides compact profile\u003c\/li\u003e\n  \u003cli\u003e2-inch shoulder-to-nut length for use with standard arbor spacer sets\u003c\/li\u003e\n  \u003cli\u003e0.95-inch shank diameter sized to R8 collet bore specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit arbor for vertical milling machines equipped with an R8 taper spindle bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or qualified toolroom technician. Power down and lock out the machine before inserting or removing the arbor from the spindle. The R8 taper should be clean and free of chips or burrs before seating; use a clean shop cloth to wipe both the arbor taper and spindle bore. Tighten the drawbar to the machine manufacturer's specification and confirm the arbor is fully seated before initiating any cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Milling Machine Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Style\u003c\/strong\u003e: Stub\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: R8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Diameter\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.95 inches (24.12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.717 inches (196 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder to Nut Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.18 pounds\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: 210-2118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706422755634,"sku":"210-2118","price":77.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a475067e36302169b0b52ef918b6fb8.jpg?v=1788434314","url":"https:\/\/voomisupply.com\/products\/value-collection-210-2118-milling-machine-arbor-r8-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
