It cuts in the right-hand direction with a straight flute geometry, producing accurate, smooth bores in a wide range of materials. The reamer measures 0.2280 inches in diameter with a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance work where hole size consistency is critical. Overall length is 3.0 inches with a 1-inch flute length. The bright, uncoated finish is standard for this carbide grade and works well across common ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in drill presses, CNC machining centers, lathes, and manual milling machines where a straight-shank tool is held in a chuck or collet. The 0.2280-inch diameter corresponds to wire gauge size No. 1, making it a practical choice for reaming holes to specific pin, dowel, or clearance fits in production and maintenance machining environments. It is suited for machinists, tool and die makers, and maintenance technicians working with metal components requiring reamed bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2280-inch diameter with +0.0001 to +0.0004-inch tolerance for close-fit bore finishing\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eStraight flute, right-hand cut geometry for stable, accurate reaming\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for use in standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — OSG Series 300D standard carbide reamer\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip clearance and surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for general machining applications requiring a 0.2280-inch finished bore diameter with a straight-shank, straight-flute configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with proper reaming technique. Secure the straight-cylindrical shank in a precision chuck or collet before operation and ensure the machine spindle is properly aligned with the pre-drilled pilot hole to prevent tool deflection or breakage. Carbide tooling is brittle — avoid interrupted cuts, side loading, or hand-feeding with excessive pressure. Follow standard shop safety practices and machine guarding requirements during use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: No. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 0.25 inches W x 0.25 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-2280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755302322482,"sku":"300-2280","price":74.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_b6f1c59e-abda-4e76-b7f0-83943fbb8082.jpg?v=1788953329","url":"https:\/\/voomisupply.com\/products\/osg-300-2280-chucking-reamer-0-2280-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
