Designed for precision hole finishing, this reamer holds a diameter tolerance of 0.0000 to 0.0003 inches, making it suitable for close-tolerance bore work in metal fabrication, machining, and toolroom applications. The bright, uncoated solid carbide construction delivers excellent rigidity and cutting-edge retention in abrasive or hard-material applications. With 6 flutes and a right-hand cutting direction, it produces a clean, consistent finish in through-holes and blind bores. Machinists and tool-and-die professionals use this style of reamer in CNC machining centers, manual mills, and drill presses.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production and maintenance machining environments where hole diameter accuracy is critical. The straight flute geometry works well in short-chipping materials such as cast iron, brass, and some aluminum alloys. The straight cylindrical shank allows it to be held in standard collets, drill chucks, or floating reamer holders. At 3.25 inches overall length with a 1.125-inch flute length, it fits standard toolholding setups on both benchtop and full-size machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter L diameter (0.2900 inches) with a tight tolerance of 0.0000 to 0.0003 inches for precision bore finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e6-flute straight flute design produces a smooth surface finish in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — ready to use as-supplied or suitable for recoating\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits collets, drill chucks, and floating holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in CNC machining centers, knee mills, and drill presses where a straight cylindrical shank and Letter L diameter are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Use a properly sized collet or floating reamer holder to minimize runout and prevent bell-mouthing of the finished bore. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Letter)\u003c\/strong\u003e: L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2900 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\u003eDiameter 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.02 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: 79891099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732578664754,"sku":"79891099","price":119.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b523be7b8b5644c9d2a06d2f7d7e5cb2.jpg?v=1788744617","url":"https:\/\/voomisupply.com\/products\/hertel-79891099-chucking-reamer-letter-l-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
