Constructed from high-speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry and a right-hand cutting direction. The small end diameter measures 1.009 inches and the large end measures 1.259 inches, with a taper rate of 1:48. The 12-inch flute length and 16-inch overall length make it suited for deep-reach applications in heavy fabrication and machine shop environments. A licensed machinist or tool and die professional typically performs this work.\u003c\/p\u003e\u003cp\u003eThis reamer is used when a tapered hole must be precisely sized to receive a standard taper pin for shaft-to-hub or component-to-component locking applications. It is appropriate for general-purpose use in metalworking, maintenance, and fabrication settings. The straight shank measures 1.25 inches in diameter, making it compatible with standard large-bore drill presses, milling machine spindles, and manual boring setups where a matching chuck or collet is available. The spiral flute promotes smooth chip evacuation during cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel construction for durability in general-purpose metalworking\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with left-hand spiral for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with 1:48 taper rate matching standard taper pin geometry\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluid\u003c\/li\u003e\n\u003cli\u003e12-inch flute length supports deep-hole finishing operations\u003c\/li\u003e\n\u003cli\u003eStraight shank at 1.25 inches diameter fits standard large-bore chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard No. 13 taper pin applications requiring a 1:48 taper rate in metalworking, fabrication, and maintenance operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed and operated by machinists or tooling professionals using a drill press, milling machine, or manual boring setup. Always secure the workpiece fully before reaming and apply an appropriate cutting fluid to extend tool life and improve finish quality. Do not force the reamer through the bore; feed at a controlled rate to avoid chatter or tool deflection. Follow applicable shop safety procedures when handling high-speed steel cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1.009 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 1.259 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: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 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\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: SM25N13\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709451174194,"sku":"SM25N13","price":342.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13f9b93c35fffa926a377dcb9cb7255f.jpg?v=1788456560","url":"https:\/\/voomisupply.com\/products\/value-collection-sm25n13-taper-pin-reamer-no-13-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
