The reamer features a spiral flute geometry with a left-hand spiral direction and right-hand cutting direction, which helps pull chips away from the work and reduces chatter during the cut. The small end diameter measures 0.706 inches and the large end measures 0.878 inches, with a taper rate of 1:48. The bright, uncoated finish suits general-purpose reaming in a wide range of workpiece materials. Machinists and tool-and-die technicians are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis taper pin reamer is used in machine shops, maintenance facilities, and manufacturing environments where taper pin holes must be accurately sized or refurbished. It is suited for both production and repair applications involving tapered hole finishing in ferrous and non-ferrous materials. The 8.25-inch flute length provides adequate engagement depth for through-hole and blind-hole reaming operations on larger workpieces. The straight shank measures 0.75 inches in diameter and seats directly in a compatible drill press chuck, lathe tailstock, or manual tap wrench setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 11 taper pin size with a 1:48 taper rate for precise pin-hole alignment\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across general-purpose cutting applications\u003c\/li\u003e\n\u003cli\u003eSpiral flute with left-hand helix and right-hand cut reduces chatter and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e8.25-inch flute length accommodates deeper reaming passes on larger stock\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight 0.75-inch shank fits standard drill press chucks and lathe tailstocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose taper pin reamer for No. 11 taper pin holes following standard taper pin sizing conventions. Suitable for use in drill presses, lathes, and manual reaming operations where a straight-shank tool is accepted.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is typically used by machinists and maintenance technicians in shop environments. Secure the workpiece firmly before reaming, and ensure the reamer is properly aligned with the existing pilot hole to avoid deflection. Apply appropriate cutting fluid to extend tool life and improve hole finish. Never force the reamer; feed with steady, controlled pressure to prevent tool breakage or hole distortion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.706 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.878 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: 8.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 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\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: SM25N11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689027731762,"sku":"SM25N11","price":145.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e094272ad91ffe16b40853e99c43edd8.jpg?v=1788254050","url":"https:\/\/voomisupply.com\/products\/value-collection-sm25n11-taper-pin-reamer-no-11-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
