Built to Series 300D standards, it produces close-tolerance bores with a reamer diameter of 0.3438 inches (11\/32 inches) and holds a diameter tolerance of +0.0001 to +0.0005 inches. The straight flute geometry and right-hand cutting direction make it well suited for through-holes and short blind-hole finishing where chip evacuation is straightforward. With an overall length of 3.5 inches and a 1.25-inch flute length, this reamer is compact enough for typical CNC machining center setups. The bright, uncoated carbide surface is appropriate for use on aluminum, brass, and other non-ferrous materials as well as some steels.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for use in machine tool spindles, including CNC machining centers, knee mills, and drill presses equipped with a collet chuck or drill chuck. Its straight-cylindrical shank allows secure clamping in standard ER collets and Jacobs-style chucks. The 6-flute configuration improves surface finish quality compared to lower-flute-count reamers, making it a practical choice for production environments where consistent bore quality is required. It is sold individually and suited for tool crib stock in job shops and production facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance for consistent sizing over high cycle counts\u003c\/li\u003e\n\u003cli\u003e6-flute straight design delivers improved surface finish in through-hole reaming operations\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0005 inches suits close-fit dowel pin and bearing bore applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating adhesion concerns when working with aluminum or brass\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank is compatible with standard ER collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eCompact 3.5-inch overall length fits short-reach setups without excessive overhang\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 applications requiring a 0.3438-inch finished bore diameter in a straight-shank, straight-flute configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer should be installed and operated by a qualified machinist or CNC operator. Secure the straight shank in a properly sized collet or chuck and verify runout before cutting to avoid bell-mouthing the bore. Power down the machine spindle completely before tool changes. Do not use this reamer as a drill — always pre-drill or bore the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\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\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 Dimensions\u003c\/strong\u003e: 4 inches L x 0.5 inches W x 0.5 inches H\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: 300-3438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753030353202,"sku":"300-3438","price":93.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_fbf9f6c1-bbff-429e-a1a5-2103bcb3f672.jpg?v=1788932262","url":"https:\/\/voomisupply.com\/products\/osg-300-3438-chucking-reamer-11-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
