Manufactured from high speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry with a right-hand cutting direction and left-hand spiral for smooth chip evacuation. The small end diameter measures 0.0719 inches and the large end measures 0.0966 inches, conforming to the standard 1:48 taper rate. Machinists and tool-room technicians use this reamer when fitting precision taper pin connections in shafts, hubs, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis taper pin reamer is suited for general-purpose hole finishing in small-diameter applications, particularly where taper pins are used to secure components on shafts or to align mating parts. The compact overall length of 2.1875 inches and 1.1875-inch flute length make it appropriate for close-tolerance work in light industrial and tool-room environments. The square shank at 0.1094 inches provides positive drive in a standard tap wrench or similar hand-holding tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, left-hand spiral geometry promotes smooth chip removal during reaming\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard forward-rotation use\u003c\/li\u003e\n  \u003cli\u003e1:48 taper rate matches the standard taper pin specification for 5\/0 pins\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eSquare shank for positive drive in a tap wrench or brace\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reamer for producing and finishing holes to accept standard 5\/0 taper pins per accepted taper pin sizing conventions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTaper pin reamers are typically used by machinists working in manual or hand-reaming operations. Secure the workpiece firmly before reaming and apply cutting fluid to extend tool life and improve finish quality. Use consistent, steady pressure and rotate the reamer without reversing direction under load, as reversing can damage the cutting edges. Always verify the finished hole with the appropriate taper pin before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 5\/0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.0719 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.0966 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 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: 1.1875 inches (1-3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1875 inches (2-3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1094 inches (7\/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\u003eSeries\u003c\/strong\u003e: 557U\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: 557u5\/0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696549429554,"sku":"557u5\/0","price":100.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcfaada33a55a6706196451629640dbf.jpg?v=1788343837","url":"https:\/\/voomisupply.com\/products\/value-collection-557u5-0-taper-pin-reamer-5-0-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
