The tool features a 6-flute spiral configuration with right-hand cutting and right-hand spiral direction, delivering a clean, accurate bore finish in a single pass. At 5.5 inches overall length with a 1.75-inch flute length, it is sized for general-purpose machine reaming operations. The bright, uncoated finish suits standard shop conditions where supplemental coatings are not required. This reamer is designed for use in a drill press, milling machine, CNC machining center, or lathe with a chuck or collet holder.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in metalworking and machining environments where bore-to-size accuracy is required. It is cataloged as an over\/under size reamer, meaning it is ground to a non-standard diameter for applications requiring a specific fit or allowance beyond a nominal size. The straight-cylindrical shank allows it to be held securely in a standard drill chuck or collet. Typical users include machinists, tool-and-die makers, and maintenance technicians in production and job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4385 inch finished reaming diameter for precise bore sizing\u003c\/li\u003e\n  \u003cli\u003e6-flute spiral design for smooth cutting action and improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand spiral direction\u003c\/li\u003e\n  \u003cli\u003eHSS construction provides good toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — ready for use as supplied\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eOver\/under size designation for applications requiring non-nominal bore fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any machine tool equipped with a chuck or collet capable of holding a straight-cylindrical shank reamer, including drill presses, milling machines, lathes, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the reamer securely in a drill chuck or collet before powering the machine. Always ream at the correct spindle speed and feed rate for the workpiece material — consult published HSS reaming data for the specific material being machined. Never attempt to chuck or remove the reamer while the spindle is in motion. Use appropriate cutting fluid to extend tool life and maintain bore finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4385 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Right Hand\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: HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: Yes\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: 72296726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753493627186,"sku":"72296726","price":86.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61b2d3eb40550056a09a0666151d5fae_53bbadef-b194-41a8-b9bf-21db05914941.jpg?v=1788937387","url":"https:\/\/voomisupply.com\/products\/hertel-72296726-chucking-reamer-0-4385-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
