It features a No. 4 Morse Taper (4MT) shank for secure, self-holding engagement in compatible machine spindles and tailstocks. With an overall length of 13 inches, the arbor provides reach and rigidity for precision reaming operations. It accepts shell reamers ranging from 2-1\/16 inches to 2-1\/2 inches in diameter, covering a practical range for production and job-shop bore finishing work. This arbor is installed and used by machinists, tool-and-die makers, and skilled trade professionals working on manual or CNC-capable lathes and boring machines.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for use in ferrous and non-ferrous metal boring and finishing operations where a shell reamer must be driven from a Morse taper spindle. Typical applications include bore sizing and finishing on lathes, drill presses, and machining centers equipped with a No. 4 Morse taper socket. The 2-1\/16 to 2-1\/2 inch diameter range makes it appropriate for medium-to-large bore work in manufacturing, maintenance, and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 4 Morse Taper (4MT) shank for self-holding fit in compatible machine spindles\u003c\/li\u003e\n  \u003cli\u003eAccepts shell reamers from 2-1\/16 inches to 2-1\/2 inches in diameter\u003c\/li\u003e\n  \u003cli\u003e13-inch overall length provides reach for deeper bore operations\u003c\/li\u003e\n  \u003cli\u003eDesigned for precision bore finishing in production and maintenance machining\u003c\/li\u003e\n  \u003cli\u003eSingle-piece arbor construction for rigidity during reaming cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with shell reamers ranging from 2-1\/16 inches to 2-1\/2 inches in diameter and machines equipped with a No. 4 Morse Taper spindle socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Before mounting, confirm the machine spindle is a No. 4 Morse Taper and that both the taper shank and socket are clean and free of chips or burrs, as contamination will prevent full seating and can cause runout. Power down and de-energize the machine before inserting or removing the arbor. Use a proper drift and dead-blow mallet for removal to avoid spindle damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (No. 4 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Shell Reamer Diameter Compatibility\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Shell Reamer Diameter Compatibility\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 13 inches\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: 331-2309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717086282034,"sku":"331-2309","price":101.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7988cd0f99ab253dc99d6f54cd653c9.jpg?v=1788535491","url":"https:\/\/voomisupply.com\/products\/value-collection-331-2309-shell-reamer-arbor-4mt","provider":"Voomi Supply","version":"1.0","type":"link"}
