Built from high speed steel with a bright, uncoated finish, this reamer maintains edge integrity across general-purpose metalworking applications. The tool features a 0.3971-inch small end diameter and a 0.5050-inch large end diameter, producing the taper required for size 8 taper pins. With a 5.1875-inch flute length and a 7.1875-inch overall length, it provides adequate reach for typical benchtop and machine-shop setups. The square shank measures 0.4375 inches and is suited for standard drill press or lathe chuck mounting.\u003c\/p\u003e\n\u003cp\u003eThis taper pin reamer is used in machine shops, maintenance facilities, and manufacturing environments where taper pins are used to lock components such as gears, collars, and levers onto shafts. The right-hand cutting direction and straight flute geometry make it appropriate for hand reaming or slow-speed machine reaming in ferrous and non-ferrous materials. It is sized for size 8 taper pins following the standard 1:48 taper rate, which is common in general mechanical assembly and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general-purpose reaming tasks\u003c\/li\u003e\n  \u003cli\u003eSize 8 taper pin geometry with a 1:48 taper rate for standard taper pin fitment\u003c\/li\u003e\n  \u003cli\u003eStraight flute design suited for hand reaming and low-speed machine reaming\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard drill press and lathe setups\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no additional coating to affect dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003eSquare shank at 0.4375 inches for secure chuck engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production reamer for size 8 taper pin applications following the standard 1:48 taper rate used in mechanical assembly and repair.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTaper pin reamers are typically used by machinists and maintenance technicians. Power down and lock out any machinery before reaming holes in installed components. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Advance the reamer slowly and back it out periodically to clear chips and prevent tool chatter or taper distortion.\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: 0.5050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 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: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Rate\u003c\/strong\u003e: 1:48\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\u003eSeries\u003c\/strong\u003e: 556U\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: 556u 8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699058082098,"sku":"556u 8","price":195.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdb6efe956c641d77b2ff6cd57c99a45.jpg?v=1788371790","url":"https:\/\/voomisupply.com\/products\/value-collection-556u-8-taper-pin-reamer-size-8-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
