Manufactured from high-speed steel with a bright, uncoated finish, this reamer delivers consistent material removal in general-purpose machining applications. It features 6 straight flutes with a right-hand cut and a taper rate of 1:48, matching the standard taper pin geometry. The small end diameter measures 0.2773 inches and the large end measures 0.354 inches. Overall length is 5.4375 inches with a flute length of 3.6875 inches. The square shank measures 0.3594 inches (23\/64 inches) in diameter. This tool is used by machinists and tool-and-die professionals working with precision assemblies that require taper pin fastening.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for use in manual machine shops, maintenance environments, and production facilities where taper pin holes must be sized or finished to close tolerances. Common applications include shaft-to-hub assemblies, gear and collar pinning, and precision fixture work. The No. 6 taper size targets mid-range pin diameters and fits applications calling for standard ASME taper pin dimensions. General-purpose tool performance makes it appropriate for mild steel, aluminum, brass, and similar machinable materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 6 taper pin size with 1:48 taper rate for standard pin fitment\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for general-purpose hole finishing\u003c\/li\u003e\n\u003cli\u003e6 straight flutes with right-hand cut for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eSquare shank at 0.3594 inches for positive drive in standard tap wrenches or machine holders\u003c\/li\u003e\n\u003cli\u003e3.6875-inch flute length provides sufficient cutting depth for typical taper pin depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard No. 6 taper pin reamer conforming to ASME taper pin geometry, suitable for use wherever a No. 6 taper pin hole must be sized or finished to specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed and operated by qualified machinists using a tap wrench, hand brace, or low-speed drill press. Always secure the workpiece firmly before reaming and apply an appropriate cutting fluid to extend tool life and improve finish quality. Feed pressure should be steady and consistent; avoid forcing the reamer or reversing rotation under load, as this can chip flutes. Inspect the reamer for wear before use and ensure the shank is fully seated in the driver.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Rate\u003c\/strong\u003e: 1:48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.2773 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.354 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.4375 inches (5-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.6875 inches (3-11\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches (23\/64 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\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: 72401060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727401189682,"sku":"72401060","price":96.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cf0a0a86cbad1757448c2bbbcb23041.jpg?v=1788677411","url":"https:\/\/voomisupply.com\/products\/hertel-72401060-taper-pin-reamer-size-6-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
