It accepts shell reamers with a bore compatibility range of 21\/32 inches to 25\/32 inches and features a straight shank with a 1\/2 inch shank diameter for secure chucking in a drill press, lathe, or milling machine. The overall length measures 9 inches, providing adequate reach for standard reaming setups. This arbor is used by machinists and toolroom technicians to precisely finish bored holes to specified tolerances when working with interchangeable shell reamer heads.\u003c\/p\u003e\n\u003cp\u003eThe 331-2002 arbor is suited for use in machine shops, toolrooms, and production environments where shell reamers are rotated to achieve precise hole sizing and smooth bore finishes. The No. 4 arbor designation corresponds to the standard shell reamer sizing system, making it a direct fit for appropriately sized reamer heads. It is appropriate for use in both manual and CNC machine setups where a straight-shank tool holder is the required interface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 4 arbor number matches standard shell reamer sizing for reliable tool engagement\u003c\/li\u003e\n  \u003cli\u003eCompatible with shell reamers ranging from 21\/32 inches to 25\/32 inches bore diameter\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight shank diameter for chucking in standard tool holders\u003c\/li\u003e\n  \u003cli\u003e9 inch overall length provides extended reach for deep or obstructed setups\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction supports accurate, chatter-resistant reaming\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept No. 4 shell reamers with a bore diameter compatibility range of 21\/32 inches to 25\/32 inches.

Secure the straight shank firmly in the machine chuck or tool holder before operation and verify that the shell reamer is properly seated and locked onto the arbor drive. Power down and de-energize the machine before mounting or removing the arbor. Inspect the arbor and reamer mating surfaces for wear or damage prior to each use to maintain bore accuracy and operator safety.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Number\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Shell Reamer Diameter Compatibility\u003c\/strong\u003e: 21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Shell Reamer Diameter Compatibility\u003c\/strong\u003e: 25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 pounds\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: 331-2002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707852489010,"sku":"331-2002","price":54.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbb41e641a4bc45b7c2b1b4597a56fb3.jpg?v=1788442518","url":"https:\/\/voomisupply.com\/products\/value-collection-331-2002-shell-reamer-arbor-no-4","provider":"Voomi Supply","version":"1.0","type":"link"}
