Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent material removal and accurate sizing in metalworking and machining applications. The straight-cylindrical shank seats securely in standard chucks and collets. With six flutes and right-hand cutting action, it produces smooth, round, and dimensionally accurate holes suitable for close-tolerance fits. Overall length is 6 inches with a flute length of 1.5 inches.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for machine shop and production environments where hole finishing to a tight tolerance is required. It is used in drill presses, lathes, CNC machining centers, and manual milling machines. The 0.2820-inch diameter falls within the 0.2500 to 0.2999 inch reamer diameter range, making it appropriate for finish-reaming operations in steel, cast iron, aluminum, and similar machinable materials. Machinists, tool-and-die makers, and production machine operators are the primary installers and users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2820-inch finished reaming diameter for close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a broad range of machinable metals\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes with right-hand cutting direction for smooth, chatter-resistant operation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 1.5-inch flute length for access in typical machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for use in any machine tool equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.2820-inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed and operated by machinists using drill presses, lathes, or machining centers — ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to prevent runout, which directly affects hole quality and tool life. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the best surface finish. Pre-drill or bore the hole to within the recommended stock allowance before reaming to avoid overloading the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2820 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 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: 0.15 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: 72028202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753758458162,"sku":"72028202","price":66.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_05a0dce0-c218-4a5d-be90-33f3c6f508b5.jpg?v=1788940362","url":"https:\/\/voomisupply.com\/products\/hertel-72028202-chucking-reamer-0-2820-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
