Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 0.4870 inches in diameter with an 8-inch overall length and a 2-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With 6 flutes cutting in a right-hand direction, it delivers smooth material removal and accurate hole sizing in ferrous and non-ferrous materials. Machinists, tool-and-die makers, and maintenance technicians rely on this style of reamer for close-tolerance finishing passes on drilled or bored holes.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for use in drill presses, lathes, and machining centers where a standard straight-shank mounting is appropriate. It is used in general-purpose machine shop environments, maintenance and repair operations, and production settings where holes in the 0.4870-inch range require a clean, finished bore. The right-hand cutting direction is compatible with conventional spindle rotation, making setup straightforward. No special toolholding beyond a standard chuck or collet is required for typical applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4870-inch reaming diameter for close-tolerance hole finishing\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes provide smooth cutting action and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction offers durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction matches conventional spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose chucking reamer for use in any machine tool accepting a straight-cylindrical shank, including drill presses, engine lathes, turret lathes, and vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer is installed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the chuck or collet is clean and properly tightened before mounting the tool. A reaming allowance of 0.005 to 0.015 inches of material removal is standard practice for chucking reamers; the specific allowance should be determined by the machinist based on workpiece material and required tolerance. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4870 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\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: 72034879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67988504019250,"sku":"72034879","price":82.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27f7c4490510e6f20e880c37731f0b81_3b0749ad-4ce2-456b-ab69-79b383863199.jpg?v=1792297757","url":"https:\/\/voomisupply.com\/products\/hertel-72034879-chucking-reamer-0-4870-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
