With a reamer diameter of 0.069 inches and a tight tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable results in close-tolerance bores. The straight flute geometry and right-hand cutting direction make it well-suited for through-hole reaming in a wide range of materials. At 1.75 inches overall length with a 0.5-inch flute length, this compact reamer is built for small-diameter work where precision is critical. It is installed and operated by machinists and tool-room professionals.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in drill presses, CNC machining centers, lathes, and other machine tool setups requiring fine bore finishing. Its straight-cylindrical shank allows direct chucking in standard collets or drill chucks. The 0.069-inch diameter puts it in the micro-reamer range, making it appropriate for precision instrument components, small fastener clearance holes, and fine mechanical assemblies where hole quality and dimensional accuracy are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter reaming\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0000 to 0.0002 inches for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design for smooth, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard machine spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct chucking without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard chucking reamer for machine tool setups requiring a 0.069-inch diameter straight-shank reamer with a straight-cylindrical shank profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer should be installed by a qualified machinist in a rigid machine tool setup to maintain concentricity and prevent tool deflection. Always secure the straight shank firmly in a precision collet or drill chuck rated for the spindle speed being used. Ensure the workpiece and machine spindle are properly aligned before reaming to avoid oversizing or bell-mouthing the bore. Apply appropriate cutting fluid for the workpiece material and never use a reamer to remove excessive stock — pre-drill or bore to within a few thousandths of the finish diameter before reaming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.069 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 79889028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747644145970,"sku":"79889028","price":59.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcf99b009dbdc728eff097e071977c5c.jpg?v=1788883984","url":"https:\/\/voomisupply.com\/products\/hertel-79889028-chucking-reamer-0-069-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
