Constructed from high speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry with right-hand cutting action and left-hand spiral direction. The small end diameter is 0.0497 inches and the large end diameter is 0.0666 inches, conforming to the 1:48 taper rate standard for taper pin applications. Machinists, tool-and-die technicians, and general machine shop personnel use this tool for precision hole preparation in metalworking operations.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for general-purpose metalworking where a No. 7\/0 taper pin fit is required. Typical applications include fitting taper pins in shafts, collars, levers, and mechanical assemblies where a secure, removable locating pin connection is needed. The compact overall length of 1.8125 inches and 5\/64-inch straight shank make it compatible with standard drill press chucks and hand-held pin vise holders used in bench-level precision work. It is appropriate for use in both production and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 7\/0 taper pin size with a 1:48 taper rate for standard taper pin hole conformance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across general-purpose ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes chip evacuation during reaming operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard machine and hand rotation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eCompact 1.8125-inch overall length fits confined workpiece access areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose tool for machines and assemblies requiring a No. 7\/0 standard taper pin hole, with a straight shank that fits standard drill chucks and pin vise holders accepting a 0.0781-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or skilled technicians using a drill press, tapping fixture, or hand-held pin vise. Secure the workpiece firmly before reaming to prevent movement and maintain hole alignment. Apply a suitable cutting fluid to extend tool life and improve surface finish. Do not force the reamer through material; feed with light, consistent pressure to avoid tool deflection or breakage on this small-diameter tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 7\/0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.0497 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.0666 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Rate\u003c\/strong\u003e: 1:48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.8125 inches (1-13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0781 inches (5\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: ATR2581\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721535062322,"sku":"ATR2581","price":30.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a16b93cccaff9d1ab3faaedeab250dac.jpg?v=1788578611","url":"https:\/\/voomisupply.com\/products\/value-collection-atr2581-taper-pin-reamer-no-7-0-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
