With a 10 mm (0.3937 inch) reamer diameter and a bright, uncoated finish, it delivers tight diameter tolerances of +0.0001 to +0.0005 inches, making it suitable for work requiring close fits and smooth bore finishes. The six-flute, straight-flute geometry provides stable cutting action and good chip evacuation. At 89 mm overall length with a 32 mm flute length, the 300-3937 fits standard drill chucks and collet holders with a straight cylindrical shank. This tool is installed and operated by machinists and tool-room professionals in CNC and manual machining environments.\u003c\/p\u003e\u003cp\u003eThe OSG 300-3937 is intended for general machining applications where precise bore sizing is required. It is well suited for reaming pre-drilled holes in metals and similar materials in both production and job-shop settings. The straight flute design performs reliably in through-hole and shallow blind-hole applications. The solid carbide construction provides rigidity and wear resistance compared to high-speed steel alternatives, making it a practical choice for shops running higher spindle speeds or harder workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in general machining\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0005 inches for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eSix straight flutes for stable cutting action and consistent 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 for compatibility with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for general machining use; fits standard straight-shank tool holders and drill chucks accepting a 10 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and the tool holder is secure before mounting or removing the reamer. Select appropriate spindle speed and feed rate for the workpiece material per standard machining practice. Inspect the reamer for chipping or wear before each use, as solid carbide tools are brittle and should not be subjected to interrupted cuts or excessive side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 89.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 32.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 300-3937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735225368882,"sku":"300-3937","price":114.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_add0dbbd-6fdd-4414-bfbe-58a9148505e5.jpg?v=1788770545","url":"https:\/\/voomisupply.com\/products\/osg-300-3937-chucking-reamer-10mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
