With a reamer diameter of 6.1 mm (0.2402 inches) and a tight diameter tolerance of +0.0001 to +0.0004 inches, this tool produces accurate, smooth bores in a wide range of workpiece materials. The straight flute geometry and right-hand cutting direction suit most standard drilling and reaming operations. At 76 mm overall length with a 25 mm flute length, it fits conventional drill chucks and collet holders. Machinists, toolmakers, and CNC operators working in job shop or production environments will find this reamer well suited to tight-tolerance hole sizing.\u003c\/p\u003e\u003cp\u003eThe 300-2402 fits general machining applications where a precise finish bore is required. The straight shank allows mounting in standard drill chucks, collet chucks, or reamer holders on lathes, drill presses, and machining centers. The bright, uncoated carbide surface is appropriate for a variety of ferrous and non-ferrous materials when coolant is applied externally. It is not configured for coolant-through delivery. This tool is part of OSG Series 300D, intended for standard carbide reaming in both low-volume job shop and higher-volume production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision reaming\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0004 inches for tight hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight flute, right-hand cut geometry suitable for most general-purpose reaming\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with external coolant application\u003c\/li\u003e\n\u003cli\u003e4-flute design for balanced cutting and smooth bore finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style chucking reamer in the OSG Series 300D, suitable for standard straight-shank reamer holders on lathes, drill presses, and machining centers requiring a 6.1 mm bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with rotating cutting tool safety. Secure the straight shank firmly in a properly sized collet or drill chuck before operation, and confirm runout is within acceptable limits for the tolerance class required. Always bring the spindle to a full stop before measuring the bore or adjusting workholding. Follow shop-specific feeds, speeds, and coolant procedures appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 6.10 mm (0.2402 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25 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 Quantity\u003c\/strong\u003e: 1\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: 300-2402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51745207877938,"sku":"300-2402","price":79.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_c63a4628-0852-4077-8bc3-9b961413bcf1.jpg?v=1788863397","url":"https:\/\/voomisupply.com\/products\/osg-300-2402-chucking-reamer-6-1-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
