Part of the OSG Series 300D, it produces accurate, smooth bores to a reamer diameter of 0.1850 inches (wire gauge size 13) with a tight tolerance of +0.0001 to +0.0004 inches. The 4-flute, straight-flute geometry with right-hand cutting direction delivers clean, consistent material removal in both manual and CNC machine tool setups. The bright, uncoated finish suits a wide range of workpiece materials where coating is not required. Machinists, toolroom technicians, and CNC operators install this reamer to bring drilled or bored holes to final dimensional specification.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for light to medium production work and toolroom operations requiring precise hole sizing in the 0.1500 to 0.1999 inch diameter range. The straight-cylindrical shank with a 0.1719 inch (11\/64 inch) shank diameter seats securely in standard drill chucks and collet holders. At 2.75 inches overall length with a 0.875 inch flute length, it fits typical short-reach applications on mills, drill presses, and lathes. It is not configured for coolant-through delivery and is not designated as a dowel pin or over\/under size reamer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in general machining\u003c\/li\u003e\n\u003cli\u003e0.1850 inch reamer diameter, wire gauge size 13, with tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e4-flute straight geometry with right-hand cutting direction for consistent finish\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.1719 inches for compatibility with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eSeries 300D standard carbide reamer for general machining use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style solid carbide chucking reamer for general machining applications in the 0.1500 to 0.1999 inch diameter range.

Secure the reamer in a properly sized drill chuck or collet holder, ensuring runout is minimized before engaging the workpiece. Power down the machine spindle completely before inserting or removing the reamer. Do not use this reamer as a drill to remove stock; pre-drill or bore the hole to within recommended allowance before reaming to final size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1850 inches (Wire Gauge 13)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1500 to 0.1999 inches\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\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\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1719 inches (11\/64 inch)\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: 300-1850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752087322930,"sku":"300-1850","price":64.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_409bf360-5402-4914-b6ba-00894966884f.jpg?v=1788925751","url":"https:\/\/voomisupply.com\/products\/osg-300-1850-chucking-reamer-0-1850-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
