Built from high-speed steel with a bright, uncoated finish, this tool produces accurate tapered bores at a 1:48 taper rate. It features four spiral flutes with a left-hand spiral direction and right-hand cutting action, which helps pull chips away from the cutting edge during operation. The small end diameter measures 0.0497 inches and the large end measures 0.0666 inches, making it sized for No. 7\/0 taper pins. Machinists and tool-and-die technicians use this reamer in manual or machine operations requiring precise hole geometry.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for general-purpose hole finishing work in machine shops, maintenance environments, and production settings where taper pin connections are used to secure hubs, collars, and similar components to shafts. The 5\/64-inch square shank is compatible with standard tap wrench drives and appropriate machine tool holders. The compact overall length of 1-13\/16 inches and 13\/16-inch flute length make it practical for close-quarter work on small assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for No. 7\/0 taper pins with a 1:48 taper rate\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for general-purpose cutting performance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flutes with right-hand cutting direction to aid chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour flutes for consistent surface finish and accurate hole geometry\u003c\/li\u003e\n  \u003cli\u003eSquare shank for positive drive in tap wrenches or machine holders\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for No. 7\/0 taper pin applications in manual and machine reaming operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is typically used by machinists and maintenance technicians. Secure the workpiece firmly before reaming and ensure proper alignment to avoid bell-mouthing the hole. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the reamer for wear or chipping before each use and do not force the tool through the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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: Square\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 Application\u003c\/strong\u003e: Hole Enlarging, Hole Finishing, Hole Shaping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72401946\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752028930354,"sku":"72401946","price":106.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96c9b14c41fb3efa5b017be4db8e202a_203b3d31-19cc-442b-91cf-fbdc4ec63d02.jpg?v=1788925338","url":"https:\/\/voomisupply.com\/products\/hertel-72401946-taper-pin-reamer-size-7-0-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
