It features a 2.1 mm diameter with a diameter tolerance of +0.0001 to +0.0004 inches, ensuring tight, repeatable fits in finished bores. The 4-flute straight configuration and right-hand cutting direction deliver smooth material removal in a wide range of workpiece materials. With a 50 mm overall length and a 12 mm flute length, this reamer is well-suited for shallow to moderate-depth holes where dimensional accuracy is critical. It is part of the OSG 300D series and ships uncoated for out-of-the-box use.\u003c\/p\u003e\u003cp\u003eThis reamer is used in CNC machining centers, manual mills, and drill presses where close-tolerance hole sizing is required. It is intended for general machining applications across ferrous and non-ferrous materials. The straight cylindrical shank seats directly into standard collet chucks or drill chucks commonly found in machine shops and production environments. Machinists and tool-and-die tradespeople working on precision components, fixtures, or assemblies will find this reamer appropriate for reaming pre-drilled pilot holes to final specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.1 mm reamer diameter with tolerance of +0.0001 to +0.0004 inches for precision bore sizing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining operations\u003c\/li\u003e\n\u003cli\u003e4-flute straight configuration for efficient chip evacuation in through and blind holes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with straight cylindrical shank for easy chuck mounting\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for immediate use without additional prep\u003c\/li\u003e\n\u003cli\u003ePart of the OSG 300D series, designed for standard general machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose chucking reamer compatible with standard collet chucks and drill chucks accepting a straight cylindrical shank in the 2.1 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck. Verify the shank is fully seated and the collet or chuck is properly tightened before operation. Always use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and bore quality, noting that this reamer does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 2.1 mm (0.0827 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12 mm\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\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 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 300-0827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751483474226,"sku":"300-0827","price":44.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_65cdaa16-100c-4f0d-8449-47d3e6085cb9.jpg?v=1788923583","url":"https:\/\/voomisupply.com\/products\/osg-300-0827-chucking-reamer-2-1mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
