With a 12 mm (0.4724 inch) reamer diameter and a total overall length of 102 mm, this tool delivers tight diameter tolerances of +0.0001 to +0.0005 inches, making it well-suited for applications where bore accuracy and surface finish are critical. The six-flute straight geometry and right-hand cutting direction provide clean, consistent material removal in a variety of workpiece materials. Machinists and tool-room professionals install this reamer in standard chucks or collets on CNC machining centers, knee mills, and drill presses.\u003c\/p\u003e\u003cp\u003eThe 300-4724 is intended for general machining environments where a reliable, uncoated solid carbide reamer is needed for sizing holes to close tolerance. The 38 mm flute length provides adequate chip clearance for through-hole and blind-hole finishing operations. The straight cylindrical shank allows direct mounting in a wide range of standard toolholders without adapters. This reamer ships individually and is appropriate for both production runs and low-volume toolroom work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining cycles\u003c\/li\u003e\n\u003cli\u003eSix straight flutes with right-hand cut for smooth, accurate hole finishing\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0005 inches for precise bore sizing\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003ePart of the OSG 300D series for general machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide chucking reamer for standard machining operations requiring a 12 mm finished bore diameter.

Secure the straight shank firmly in a precision collet or drill chuck before use, and verify runout with a dial indicator before taking a finishing pass. Always power down the spindle completely before changing or adjusting the tool. Do not exceed the recommended feed and speed parameters for solid carbide tooling in the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 102.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 38.00 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 300-4724\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736273125682,"sku":"300-4724","price":187.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_042ac9a5-7bcd-4bd5-9fd8-bfd740474a6a.jpg?v=1788776910","url":"https:\/\/voomisupply.com\/products\/osg-300-4724-chucking-reamer-12mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
