Built from high-speed steel (HSS) with a bright uncoated finish, it delivers accurate sizing and smooth bore surfaces in steel, aluminum, brass, and similar machinable materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. With an overall length of 2.5 inches and a 0.5 inch flute length, this reamer is sized for close-tolerance finish work on small-diameter holes where dimensional accuracy is critical. Machinists and tool-and-die professionals reach for this style of reamer when a drilled hole needs to be brought to a precise final size.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for machine shop, production, and maintenance applications where small-diameter holes must meet tight tolerances. It is used in drill presses, lathes, and milling machines. Typical applications include finishing pilot holes, pin holes, and bearing bores in both prototype and production environments. It is appropriate for use on ferrous and non-ferrous metals as well as some plastics where a clean, dimensionally accurate bore is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0640 inch reaming diameter for small-bore precision finishing\u003c\/li\u003e\n\u003cli\u003e4 straight flutes provide clean cutting action and easy chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction offers good hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose use across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional machine operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, lathes, and milling machines equipped with standard drill chucks or collet holders sized to accept a straight-cylindrical shank in the 0.0500 to 0.0999 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA qualified machinist should install and operate this reamer. Always secure the workpiece and ensure the spindle is fully stopped before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed recommended feed rates for the material being reamed, as excessive force can cause tool deflection or breakage in small-diameter reamers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0640 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 72006406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67909664506162,"sku":"72006406","price":40.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_9ec6728f-61d2-40f8-98af-fe8603e52353.jpg?v=1791189651","url":"https:\/\/voomisupply.com\/products\/hertel-72006406-chucking-reamer-0-0640-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
