Built from high-speed steel with a bright, uncoated finish, this reamer produces accurate, smooth bores at a nominal diameter of 0.3750 inches (3\/8 inch). It features six flutes with a right-hand cutting direction, providing clean material removal and consistent surface finish. The straight shank is compatible with standard drill chucks and collet systems. With an overall length of 7 inches and a flute length of 1-3\/4 inches, it suits a broad range of through-hole and blind-hole reaming operations performed by machinists and tool-room professionals.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for production and job-shop environments where controlled hole sizing is required after drilling. It is used in machine shop applications involving ferrous and non-ferrous metals, where close-tolerance bore finish is needed. The straight-flute geometry is particularly effective in materials that produce short, broken chips. It is typically run in CNC machining centers, knee mills, drill presses, and manual lathes with chuck mounting. The right-hand cut and six-flute configuration support consistent stock removal at standard reaming speeds and feeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes with right-hand cut for smooth, controlled material removal\u003c\/li\u003e\n  \u003cli\u003eNominal diameter of 0.3750 inches for precise 3\/8 inch bore sizing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids in standard reaming operations\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with drill chucks and standard collet holders\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7 inches with a 1-3\/4 inch flute length for versatile reach in common workpiece depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in drill chucks, end mill holders, and collet systems accepting a straight shank at the 3\/8 inch diameter class in standard machine tool setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eReamer installation and operation should be performed by qualified machinists familiar with cutting tool safety. Secure the straight shank firmly in a chuck or collet, ensuring minimal runout before beginning the cut. Always apply appropriate cutting fluid and operate at recommended reaming speeds — typically lower than drilling speeds for the same material — to achieve proper bore finish and tool life. Inspect the reamer for wear or chipping before each use and do not force the tool through undersized or improperly prepared holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches (177.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches (44.45 mm)\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\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  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3500 - 0.3999 inches\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: C25807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697541939506,"sku":"C25807","price":83.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfeb91b41ddfb6bfe600295245ea2d30.jpg?v=1788352638","url":"https:\/\/voomisupply.com\/products\/cleveland-c25807-chucking-reamer-3-8-in-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
