With a decimal diameter of 0.2010 inches, 6 spiral flutes with right-hand spiral direction, and a straight-cylindrical shank, this reamer is built for use in drill presses, lathes, and CNC machining centers. The 3-5\/8-inch overall length and 1-1\/4-inch flute length make it well suited for shallow-to-medium depth reaming passes where tight hole tolerances are required. Machinists and tool-and-die professionals use this style of reamer as a finishing tool after drilling to achieve accurate diameters and smooth bore finishes.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for production and maintenance machining environments where wire-gauge-sized holes in the 0.2000 to 0.2499 decimal inch range are required. It is a standard fitment for general metalworking applications including jig and fixture work, precision hole sizing in ferrous and non-ferrous materials, and component repair. The straight-cylindrical shank allows direct chucking in standard drill chucks or collet holders without adapters, streamlining setup time on both manual and CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 7 reamer diameter — 0.2010 inches decimal for precision hole finishing\u003c\/li\u003e\n\u003cli\u003eHSS construction provides durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e6 right-hand spiral flutes for smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003e3-5\/8 inches overall length with 1-1\/4 inch flute length for controlled depth passes\u003c\/li\u003e\n\u003cli\u003eNot an over\/under size reamer — ground to standard wire gauge 7 nominal diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer replacement for wire size 7 applications in general metalworking, drill press, lathe, and CNC machining setups requiring a straight-cylindrical shank HSS reamer in the 0.2000 to 0.2499 decimal inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists and toolroom technicians in machine tool spindles using a drill chuck or collet holder matched to the shank diameter. Always ensure the workpiece and machine spindle are properly secured before beginning a reaming pass. Run reamers at lower RPM than drilling operations and use appropriate cutting fluid to extend tool life and improve finish quality. Inspect the flutes and cutting edges for wear or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 inches\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: 72294077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748564435250,"sku":"72294077","price":56.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c26009126499e218bbcd7aa61ac64bab_bdf1e45b-df61-4f38-90fa-811826a95820.jpg?v=1788895251","url":"https:\/\/voomisupply.com\/products\/hertel-72294077-chucking-reamer-wire-size-7-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
