Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing of drilled or bored holes to a final diameter of 27\/64 inch (0.4219 inch decimal). The 6-flute, left-hand spiral geometry with right-hand cutting action reduces chatter and improves surface finish in through-hole and blind-hole applications. Overall length is 7 inches with a 1-3\/4 inch flute length. This reamer is installed by machinists and tool-and-die professionals using standard drill press, CNC, or lathe setups.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for ferrous and non-ferrous materials in general-purpose machining operations. It is commonly used in job shops, maintenance and repair facilities, and production lines where repeatable hole geometry is required. The straight-cylindrical shank is compatible with standard collet chucks, drill chucks, and machine tool holders, making it easy to integrate into existing setups without special tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64 inch (0.4219 inch) finished hole diameter for precise sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e6-flute, left-hand spiral design reduces chatter and promotes smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard machine rotation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating to interfere with close-tolerance fits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, lathes, CNC machining centers, and similar machine tools equipped with straight-shank toolholders or collet chucks accepting a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers should be installed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a correctly sized collet or drill chuck to secure the straight shank with minimal runout, as excessive runout will degrade hole accuracy and tool life. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface 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: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 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: Left 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 (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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 2410272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728748020018,"sku":"2410272","price":91.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f7a653dd5f1f69a3d8674c9fe07b9e4_00b2dd63-1ca2-4999-bc92-f7f22d9a131a.jpg?v=1788695778","url":"https:\/\/voomisupply.com\/products\/hertel-2410272-chucking-reamer-27-64-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
