Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth surface finish in production and job-shop environments. The reamer measures 0.4450 inches in diameter with a 7-inch overall length and a 1.75-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks and collet holders. Six right-hand cutting flutes distribute cutting load evenly and help control chip evacuation during through-hole and blind-hole finishing operations.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for machine-shop and maintenance applications where bore tolerances require a final finishing pass after drilling. Typical use cases include CNC lathes, drill presses, and milling-machine setups where a 0.4450-inch finished bore is required. It is appropriate for ferrous metals, non-ferrous alloys, and similar machinable materials. Licensed machinists and toolroom technicians are the primary users. The straight-flute geometry makes it a reliable choice for through-holes and interrupted cuts where flute direction is less critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4450-inch diameter for precision bore finishing within the 0.4000-0.4999 inch range\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides durability across a broad range of machinable materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ready to use out of the package with no coating to chip or flake\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes with right-hand cutting direction for smooth, consistent material removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length with 1.75-inch flute length suited for typical depth-of-cut requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a drill chuck or collet holder sized for a straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout before cutting. Always ream at appropriate speeds and feeds for the workpiece material — reaming RPM is typically lower than drilling RPM for the same diameter. Do not use this reamer as a primary drilling tool; always pre-drill or bore the hole to within a few thousandths of the finished diameter before reaming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4450 inches\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: 1.75 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: Straight\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\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: 72034457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749268947250,"sku":"72034457","price":75.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_38a9b2cb-478c-4326-8c4e-68c58d5a060c.jpg?v=1788903827","url":"https:\/\/voomisupply.com\/products\/hertel-72034457-chucking-reamer-0-445-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
