It cuts in the right-hand direction with six straight flutes and features a straight cylindrical shank for secure chuck mounting. The reamer diameter is 0.2720 inches, falling within the Letter I size range, and holds a tight diameter tolerance of 0.0000 to 0.0003 inches. Overall length is 3.25 inches with a flute length of 1.125 inches. The bright, uncoated carbide construction makes it well suited for demanding hole-finishing operations where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in machine shop and production environments where pre-drilled or bored holes must be brought to a precise finished diameter. Typical applications include reaming holes in steel, cast iron, aluminum, and similar machinable materials. It is intended for use in drill presses, lathes, CNC machining centers, and manual milling machines equipped with a standard chuck. The straight flute geometry is particularly effective in through-hole applications and softer materials where chip evacuation is straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision reaming operations\u003c\/li\u003e\n  \u003cli\u003eLetter I diameter of 0.2720 inches with a tolerance of 0.0000 to 0.0003 inches for accurate finished bores\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes provide stable cutting action and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with a wide range of cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for reliable chuck or collet holding\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 3.25 inches with a 1.125-inch flute length for use in confined setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, or floating holders on drill presses, lathes, and machining centers that accept straight-shank tooling in the applicable diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed and operated by machinists following standard machine tool setup procedures. Always power down and lock out the machine before changing tooling. Ensure the shank is fully seated and securely clamped in the chuck or collet before starting the spindle. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole finish quality, and feed at a rate consistent with carbide tooling recommendations for the material being reamed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Letter)\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2500 to 0.2999 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 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: 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\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: 0.1 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: 79891065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733480079666,"sku":"79891065","price":119.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/113a9099c6e45f2cc2e6ea0a75903f4c.jpg?v=1788755772","url":"https:\/\/voomisupply.com\/products\/hertel-79891065-solid-carbide-chucking-reamer-letter-i","provider":"Voomi Supply","version":"1.0","type":"link"}
