Manufactured from high-speed steel (HSS) with a bright\/uncoated finish, this reamer features three helical flutes with a right-hand cutting direction. The small end diameter is 0.1813 inches and the large end diameter is 0.2294 inches, producing a 1:48 taper rate consistent with standard taper pin specifications. Machinists, toolroom technicians, and maintenance professionals use this tool in manual or machine-powered reaming applications.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for general-purpose metalworking tasks where a No. 3 taper pin fit is required. Typical applications include finishing tapered bores in shafts, hubs, and mechanical assemblies that will be secured with a standard No. 3 taper pin. The straight shank measures 15\/64 inches (0.2344 inches decimal) in diameter, making it compatible with standard drill chucks and collet holders. The helical flute geometry promotes smooth chip evacuation and consistent surface finish in both ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 3 taper pin size with a 1:48 taper rate for standard taper pin fitment\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003eThree helical flutes with right-hand cutting direction for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight shank at 15\/64 inches for compatibility with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eOverall length of 3-11\/16 inches with a 2-5\/16 inch flute length for reach and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose No. 3 taper pin reamer for use in standard taper pin reaming applications across metalworking and maintenance environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer should be used by qualified machinists or maintenance technicians familiar with reaming operations. Secure the straight shank firmly in a drill chuck or collet before use, and ensure the workpiece is properly fixtured to prevent movement. Apply a suitable cutting fluid to extend tool life and improve surface finish. Never exceed the recommended feed rate for the material being reamed, and inspect the cutting edges before each use for signs of wear or chipping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.1813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.2294 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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inches (0.2344 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/16 inches (2.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-11\/16 inches (3.6875 inches)\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 72403033\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730429346098,"sku":"72403033","price":80.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90603273b53f4a451de965caab6aab0e_2e336ea7-d3a7-4aa1-8ddb-85d8ffa6dacf.jpg?v=1788717312","url":"https:\/\/voomisupply.com\/products\/hertel-72403033-taper-pin-reamer-no-3-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
