Built to Series 300D standards, it produces accurate, smooth bores with a tight diameter tolerance of +0.0001 to +0.0005 inches. The reamer measures 0.5000 inches in diameter with a 4-inch overall length and a 1-1\/2-inch flute length. Its six straight flutes and right-hand cutting direction make it well suited for CNC machining centers, drill presses, and manual lathes where consistent bore quality is required. The bright, uncoated finish preserves the carbide edge geometry without added coating variables.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for machine-tool use in production and job-shop environments. The straight cylindrical shank seats directly in collet chucks or drill chucks without modification. It is appropriate for finishing pre-drilled holes in ferrous and non-ferrous materials where dimensional accuracy and surface finish are critical. The part is sold individually and is suited for both production runs and single-part work where a standard carbide reamer meets tolerance requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0005 inches for tight, repeatable bore sizing\u003c\/li\u003e\n\u003cli\u003eSix straight flutes for smooth chip evacuation and consistent finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct mounting in collet or drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style chucking reamer for general machining applications requiring a 0.5000-inch finished bore diameter in machine-tool setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Secure the straight shank firmly in a collet chuck or drill chuck before use, and verify runout with a dial indicator before cutting. Power down and lock out the machine spindle before changing or adjusting the reamer. Do not use this tool as a drill to remove stock; ream only pre-drilled or bored holes that are already within recommended pre-ream allowance for carbide reamers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\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: 300-5000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734008365362,"sku":"300-5000","price":214.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_02e01ce5-a4f7-4875-8d38-bac3c9c127ab.jpg?v=1788760454","url":"https:\/\/voomisupply.com\/products\/osg-300-5000-chucking-reamer-1-2-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
