Constructed from high-speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry with right-hand cutting action and left-hand spiral direction, which helps pull chips away from the cutting zone during operation. The small end diameter measures 0.1813 inches and the large end measures 0.2294 inches, with a taper rate of 1:48. The straight shank measures 0.2344 inches in diameter. This tool is suited for machinists, tool-and-die workers, and maintenance technicians working in metalworking and general fabrication environments.\u003c\/p\u003e\u003cp\u003eThis reamer is used in applications requiring precision tapered hole finishing where a taper pin will be driven or pressed to create a secure mechanical connection. Typical uses include shaft-to-hub connections, linkage assemblies, and fixture work in both production and maintenance settings. The general-purpose performance rating makes it appropriate for a wide range of ferrous and non-ferrous workpiece materials at moderate cutting speeds.\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 standardized fitment\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with left-hand spiral promotes chip evacuation during right-hand cutting\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight shank at 0.2344 inches diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eFlute length of 2.3125 inches provides ample cutting depth for typical taper pin bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or stock reamer for No. 3 standard taper pin applications per ASME taper pin sizing conventions.

Secure the workpiece firmly before reaming to prevent movement. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never force the reamer; advance with steady, controlled pressure to avoid tool breakage or out-of-tolerance hole geometry.\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\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.6875 inches (3-11\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inches (15\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241617\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SM25N03\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697431347506,"sku":"SM25N03","price":23.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18aafb31b860a1eedd6500f0337a2f5f.jpg?v=1788351591","url":"https:\/\/voomisupply.com\/products\/value-collection-sm25n03-taper-pin-reamer-no-3-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
