With a reamer diameter of 0.2055 inches (wire size #5) and a diameter tolerance of +0.0001 to +0.0004 inches, this tool holds tight tolerances required for close-fit bores. The bright, uncoated finish suits a wide range of workpiece materials. Four straight flutes and a straight cylindrical shank make it compatible with standard drill chucks and collet holders. Overall length is 3.0 inches with a 1-inch flute length. This reamer is part of the OSG 300D series and is intended for use by machinists and tool-and-die professionals on manual and CNC equipment.\u003c\/p\u003e\u003cp\u003eThe 300-2055 is suited for reaming through-holes and blind holes in general machining environments, including job shops and production floors. Right-hand cutting direction and straight flute geometry make it appropriate for materials where chip evacuation is manageable without spiral geometry. Coolant-through capability is not featured on this tool, so conventional flood coolant or cutting oil applied externally is the standard approach. It is not an over\/under size reamer and is not configured as a dowel pin reamer, making it a standard-dimension general-purpose tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReamer diameter of 0.2055 inches with tolerance of +0.0001 to +0.0004 inches for precision bore finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in general machining\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003ePart of the OSG 300D series for standard carbide reaming applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style solid carbide chucking reamer for standard hole-finishing operations on CNC and manual machining equipment that accept straight cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with cutting tool setup. Secure the straight shank firmly in a drill chuck or precision collet holder, verifying runout before cutting. Ensure the workpiece is properly fixtured and the machine is at a complete stop before loading or unloading the tool. Apply appropriate external cutting fluid or flood coolant during use, as this tool 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: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: #5\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\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\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\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: 300-2055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747899769138,"sku":"300-2055","price":71.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_8f434cd5-0303-4017-ba2e-f37f3fce1c36.jpg?v=1788886834","url":"https:\/\/voomisupply.com\/products\/osg-300-2055-chucking-reamer-0-2055-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
