With a reamer diameter of 0.8 mm (0.0315 inches) and a diameter tolerance of +0.0001 to +0.0004 inches, this tool delivers consistent, tight-tolerance bores in a single pass. The straight flute geometry and right-hand cutting direction make it well-suited for through-hole and blind-hole reaming in a wide range of workpiece materials. It ships uncoated (bright finish), which keeps regrinding straightforward. The overall length is 38 mm with a 10 mm flute length, and the straight cylindrical shank mounts directly in a standard collet or drill chuck. Tool material is solid carbide throughout, providing rigidity at this small diameter.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for use in CNC machining centers, manual mills, drill presses, and precision lathes where accurate bore sizing is required. It falls within the OSG 300D series, positioned for general machining work across job shops, production facilities, and toolrooms. The 0.8 mm diameter makes it appropriate for small-bore finishing operations common in medical device manufacturing, electronics, instrumentation, and precision mechanical assemblies. Installation is performed by machinists or toolroom technicians working with micro-diameter cutting tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance at 0.8 mm diameter\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0004 inches for tight, repeatable bore sizing\u003c\/li\u003e\n\u003cli\u003eStraight flute design with right-hand cut suitable for general through-hole and blind-hole reaming\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish facilitates easy regrinding and visual inspection\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup in standard machining environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement chucking reamer for general machining applications requiring a 0.8 mm finished bore diameter in CNC or manual machine tool setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and toolroom professionals familiar with small-diameter carbide tooling. Always secure the straight shank in a properly sized, clean collet or drill chuck before operation, and verify runout with a dial indicator when tolerances are critical. Carbide is brittle at this diameter — avoid side loading, interrupted cuts, or using the reamer to remove more stock than the tool specification allows. Follow the machine tool manufacturer guidelines for spindle speed and feed rate for micro-diameter carbide reamers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.8 mm (0.0315 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\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10 mm\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\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 0.25 inches W x 0.25 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: 300-0315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752935784754,"sku":"300-0315","price":44.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_7be5f000-5a08-4892-92c4-d2c1c997298d.jpg?v=1788931292","url":"https:\/\/voomisupply.com\/products\/osg-300-0315-chucking-reamer-0-8mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
