Built from high-speed steel (HSS) with a bright, uncoated finish, it holds a nominal diameter of 0.3160 inches, which falls within the Letter O size range. The reamer features 6 flutes in a straight configuration with a right-hand cut, delivering consistent, accurate bore geometry in drilling and boring operations. Overall length is 6 inches with a flute length of 1.5 inches. It is installed and operated by machinists and tool-and-die professionals using a lathe, drill press, or CNC machine with a standard chuck.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for finishing holes in steel, cast iron, aluminum, and similar machinable materials where tight tolerances and smooth surface finish are required. The straight shank allows direct mounting in a chuck or collet on standard machine tools. Typical applications include production machining, job shop work, and maintenance operations where Letter O bore sizing is specified. The HSS construction provides reliable performance across a broad range of ferrous and non-ferrous workpiece materials at conventional cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter O nominal diameter, 0.3160 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes with right-hand cut for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight shank for direct chuck or collet mounting\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 1.5-inch flute length for controlled reaming depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style machine reamer for use in lathes, drill presses, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-shank tool in the Letter O diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or qualified tooling technician. Secure the straight shank firmly in a calibrated chuck or collet before operation, and verify runout with a dial indicator to maintain bore accuracy. Power down and de-energize the machine spindle completely before changing or seating the reamer. Apply an appropriate cutting fluid for the workpiece material to extend tool life and achieve the target surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Letter)\u003c\/strong\u003e: O\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.3160 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3000 to 0.3499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C25669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694575124786,"sku":"C25669","price":75.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78c3132add9f353c3dc7dd5b52079e6e.jpg?v=1788325687","url":"https:\/\/voomisupply.com\/products\/cleveland-c25669-chucking-reamer-letter-o-hss-6-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
