With a 5 mm (0.1969 inch) reamer diameter and a tight tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable bore sizing in production and maintenance environments. The straight, four-flute geometry and bright uncoated finish make it well suited for controlled finishing passes in a wide range of workpiece materials. At 3 inches overall length with a 1 inch flute length, it fits standard chucking setups on CNC machining centers, drill presses, and manual lathes. Licensed machinists, tool and die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis reamer is used in precision machining operations where drilled or bored holes require a tight dimensional finish. The straight cylindrical shank allows secure seating in standard collet chucks or drill chucks. It is appropriate for through-holes and blind holes in ferrous and non-ferrous metals where consistent 5 mm bore sizing is required. The right-hand cutting direction is the standard for conventional feed-in operation. With a 1 inch flute length, it is best suited for shallow to moderate hole depths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 mm reamer diameter with a tolerance of 0.0000 to 0.0002 inches for precise bore sizing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eFour straight flutes for smooth, consistent cutting action\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids in general machining\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for compatibility with standard collet and drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction — standard for conventional chucking reamer operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production chucking reamer for use in any machine tool equipped with a standard straight-shank collet or drill chuck capable of holding a 5 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists in CNC or manual machine tool setups. Ensure the machine spindle and workpiece are fully stopped before inserting or removing the tool from the chuck. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use a reamer to remove excessive stock — pre-drill or bore the hole to near-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: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 79891271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728712335666,"sku":"79891271","price":92.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/180e7840ef0bd74431836ec70e54d0b9.jpg?v=1788695371","url":"https:\/\/voomisupply.com\/products\/hertel-79891271-chucking-reamer-5mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
