Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy when enlarging and finishing drilled or bored holes to a final diameter of 0.2745 inches. The straight-cylindrical shank makes it compatible with standard drill chucks and collet holders. With a 6-inch overall length and a 1.5-inch flute length, this reamer suits moderate-depth finishing passes in a range of workpiece materials. Right-hand cutting direction is standard for conventional CNC and manual machining setups.\u003c\/p\u003e\u003cp\u003eThis reamer is used in machine shops, maintenance facilities, and production environments where close-tolerance hole finishing is required. It is suited for use in drill presses, lathes, CNC machining centers, and manual milling machines. Typical applications include fitting close-tolerance pins, bushings, and dowels in metal components. Machinists and tool-and-die technicians are the primary installers and operators of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2745-inch finished diameter in the 0.2500 to 0.2999-inch range for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e6-flute straight configuration provides smooth cutting action and a good surface finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction offers durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish with no additional coating — ready for immediate use\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank with a 0.2745-inch reaming diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and tool-and-die technicians in a machine tool setup. Always ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck or collet. Use an appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed and speed ranges for HSS tooling in your specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2745 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.2500 to 0.2999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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: High-Speed Steel (HSS)\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: 0.15 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: 72027451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732477772082,"sku":"72027451","price":72.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_72f4cb99-eec2-45a1-80ec-aaae188680e1.jpg?v=1788743351","url":"https:\/\/voomisupply.com\/products\/hertel-72027451-chucking-reamer-0-2745-in-hss-straight","provider":"Voomi Supply","version":"1.0","type":"link"}
