It features 6 straight flutes with a right-hand cut and a bright\/uncoated finish. The reamer has a small end diameter of 0.3971 inches and a large end diameter of 0.505 inches, with a taper rate of 1:48. The 7\/16-inch square shank provides positive drive in standard reamer holders. Machinists and toolroom technicians use this tool for precision sizing and finishing of taper pin holes in metal components requiring tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis taper pin reamer is suited for general-purpose machining applications in job shops, maintenance facilities, and production environments. It is designed to ream holes to accept standard Size 8 taper pins in assemblies where secure, removable pin connections are required. Typical applications include mechanical assemblies, tooling fixtures, and component alignment work across a range of ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 8 taper pin geometry with 1:48 taper rate for standard taper pin fitment\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes for consistent chip evacuation and smooth hole finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for use with conventional drill press and lathe setups\u003c\/li\u003e\n  \u003cli\u003eSquare shank provides positive engagement in standard holders and tap wrenches\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Size 8 taper pin reamer compatible with holders and chucks accepting a 7\/16-inch square shank; intended for use wherever Size 8 taper pin holes are required per standard taper pin specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist using appropriate cutting fluid for the workpiece material. Secure the workpiece firmly before reaming and ensure the reamer is aligned with the pilot hole to prevent deflection and tool damage. Apply consistent feed pressure and avoid reversing the reamer under load, as this can damage the cutting edges. Follow applicable shop safety procedures including eye protection and secure guarding when operating rotary tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.3971 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.505 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Rate\u003c\/strong\u003e: 1:48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.1875 inches (7-3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.1875 inches (5-3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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  \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: 72401086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747493544242,"sku":"72401086","price":135.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cf0a0a86cbad1757448c2bbbcb23041_00e76a01-a8cc-4731-a9ee-6247ada769a5.jpg?v=1788881310","url":"https:\/\/voomisupply.com\/products\/hertel-72401086-taper-pin-reamer-size-8-hss-6-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
