With a cutting diameter of 0.4990 inches and a 2-inch flute length, this reamer removes minimal stock while delivering tight dimensional tolerances and a clean bore surface finish. The 8-inch overall length and straight-cylindrical shank make it compatible with standard drill chucks and collet holders on lathes, drill presses, and machining centers. The bright, uncoated HSS construction is well suited to general-purpose reaming in a range of workpiece materials. This tool is installed and operated by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis reamer is used for finishing operations where hole diameter accuracy is critical, such as fitting dowel pins, close-tolerance bushings, or precision-fit shaft bores. The right-hand cutting direction is standard for conventional machine reaming. The 6-flute configuration distributes cutting forces evenly around the bore, reducing chatter and improving surface finish in both ferrous and non-ferrous materials. Typical applications include general machining in light manufacturing, maintenance repair, and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4990-inch cutting diameter for close-tolerance hole finishing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of materials\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes for even load distribution and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction — standard for machine reaming\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eOver\/under size reamer — confirmed as an undersized variant for controlled stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with drill chucks or collet holders accepting a straight-cylindrical shank of 0.4990-inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed by machinists in a drill chuck or collet holder; ensure the shank is fully seated and the tool runs true before engaging the workpiece. Always apply a suitable cutting fluid appropriate to the workpiece material to extend tool life and improve bore finish. Reaming removes a small amount of material and should follow a pre-drilled or bored hole that is already close to final diameter. Do not use a reamer to open up an undersized hole significantly, as this will overload the flutes and damage the cutting edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4990 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 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\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 (High-Speed Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches length x 0.5 inches width x 0.5 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 2557494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755754651954,"sku":"2557494","price":97.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27f7c4490510e6f20e880c37731f0b81_2b8de19c-2683-4403-86ac-7e3308166e78.jpg?v=1788959207","url":"https:\/\/voomisupply.com\/products\/hertel-2557494-chucking-reamer-0-4990-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
