With a reamer diameter of 5.10 mm (0.2008 inch) and a tight tolerance of +0.0001 to +0.0004 inches, this tool delivers accurate, repeatable bore sizing in production and job-shop environments. The 4-flute straight geometry provides smooth cutting action and consistent surface finish. At 76 mm overall length with a 25 mm flute length, it fits standard drill chucks and collet holders. The bright, uncoated solid carbide construction handles a broad range of workpiece materials including steel, cast iron, aluminum, and non-ferrous alloys.\u003c\/p\u003e\n\u003cp\u003eThe OSG 300-2008 is suited for CNC machining centers, manual mills, and drill presses where precise hole sizing to 5.10 mm is required. It is appropriate for through-hole and blind-hole finishing in general metalworking, tool-and-die, and production machining. The straight shank accepts standard ER collets and drill chuck toolholders. It is not configured for coolant-through applications and is not an over- or under-size reamer. Machinists and tool crib managers sourcing a standard OEM-style carbide reamer for light-to-medium production work will find this a direct fit for the Series 300D lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in general machining\u003c\/li\u003e\n  \u003cli\u003eReamer diameter: 5.10 mm (0.2008 inch) with tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e4-flute straight geometry for smooth, consistent bore finish\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, standard configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style chucking reamer for general machining applications requiring a 5.10 mm finished bore diameter; fits standard straight-shank toolholders and ER collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and the tool is securely clamped in a properly sized collet or drill chuck before operation. Follow the machine tool manufacturer and applicable shop safety guidelines when setting speeds and feeds for carbide reamers. Inspect the cutting edges for chips or wear before each use and replace the tool if damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 5.10 mm (0.2008 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 5.00 - 6.00 mm (0.2000 - 0.2499 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 76 mm (approximately 2.99 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25 mm (approximately 0.98 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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: 3.5 inches length x 0.5 inches width x 0.5 inches height\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: 300-2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727081210162,"sku":"300-2008","price":71.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f.jpg?v=1788672997","url":"https:\/\/voomisupply.com\/products\/osg-300-2008-chucking-reamer-5-1mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
