Built from high-speed steel (HSS), this reamer delivers consistent cutting performance across a range of ferrous and non-ferrous materials. The spiral flute geometry with left-hand spiral direction promotes smooth chip evacuation while the right-hand cutting direction provides controlled material removal. With a small end diameter of 0.5799 inches and a large end diameter of 0.7216 inches, this tool conforms to the No. 10 taper pin standard at a 1:48 taper rate. It is a general-purpose tool suited for machine shops, maintenance facilities, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis taper pin reamer is used wherever tapered holes must be precisely sized to seat taper pins in mechanical assemblies — including shafts, hubs, linkages, and structural connections. The 6.8125-inch flute length provides ample cutting surface for deep-hole applications, while the 5\/8-inch square shank allows secure chuck or holder engagement. Machinists, toolmakers, and maintenance technicians install this reamer using a standard drill press, milling machine, or hand brace setup depending on the application and material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 10 taper pin size with 1:48 taper rate for precise taper pin fitment\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across general-purpose cutting applications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flute geometry promotes efficient chip evacuation during right-hand cutting\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on most common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSquare shank design provides positive drive and prevents slippage in chuck or holder\u003c\/li\u003e\n  \u003cli\u003e6.8125-inch flute length accommodates deeper hole finishing requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement and production taper pin reamer for No. 10 taper pin applications conforming to the 1:48 standard taper rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer is installed and operated by machinists or maintenance technicians using a drill press, milling machine, or compatible hand tool with a chuck or collet holder sized for the 5\/8-inch square shank. Power down all equipment and secure the workpiece before mounting the reamer. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and achieve a clean finish. Avoid excessive feed pressure, which can deflect the tool and result in an oversized or out-of-round hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.5799 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.7216 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 Length\u003c\/strong\u003e: 6.8125 inches (6-13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.3125 inches (9-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Square\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\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\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: 557u 10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713305739570,"sku":"557u 10","price":275.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06095118e952ad91c4a4fcb8cd27fedd.jpg?v=1788492697","url":"https:\/\/voomisupply.com\/products\/value-collection-557u-10-taper-pin-reamer-no-10-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
