Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing in a wide range of metals and materials. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. With 6 flutes and right-hand cutting action, it produces clean, consistent hole walls in both through-hole and blind-hole applications. Overall length is 7 inches, and the flute length is 1.75 inches, making it well-suited for moderate-depth reaming tasks.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in machine shops, maintenance facilities, and production environments where tight hole tolerances are required. It is classified as an over\/under size reamer, meaning it is ground to a specific diameter outside the nominal standard, allowing machinists to hit precise fit classes. Typical applications include reaming holes for pins, bushings, and precision fasteners in ferrous and non-ferrous workpieces. Installation is performed on drill presses, lathes, CNC machining centers, or manual milling machines using a floating reamer holder or rigid chuck setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.3760-inch finished hole diameter with over\/under size designation for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes with right-hand cutting direction for smooth, consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eHSS construction provides good wear resistance and toughness across a broad material range\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length with 1.75-inch flute length for controlled depth reaming\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a machine chucking reamer for use in standard drill chucks, collet holders, and floating reamer holders on drill presses, lathes, and machining centers.

A floating holder is recommended to allow the reamer to self-align with the existing hole and prevent bell-mouthing. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Ensure the machine spindle is at the correct RPM for the material and reamer diameter before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.3760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3500 to 0.3999 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eOver\/Under Size Reamer\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\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: 2557387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732986167602,"sku":"2557387","price":64.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_d5ff3146-ebbb-4f50-aec6-b6b9336226e6.jpg?v=1788750032","url":"https:\/\/voomisupply.com\/products\/hertel-2557387-chucking-reamer-0-376-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
