Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate hole finishing in close-tolerance machining applications. The straight-cylindrical shank is designed for secure chuck mounting in drill presses, CNC machining centers, and manual lathes. With four right-hand cutting flutes and a 7\/8-inch flute length across a 2-3\/8-inch overall length, this reamer is suited for precision finishing of small-diameter through-holes where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in machine shops, maintenance facilities, and production environments where wire-gauge hole sizes must be held to tight tolerances. It is appropriate for finishing pre-drilled holes in ferrous and non-ferrous metals, plastics, and other machinable materials. The compact overall length and small diameter make it particularly well suited for precision work on small components, instrument parts, and fine mechanical assemblies requiring controlled bore sizing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 39 reamer diameter of 0.0995 inches for precise small-bore finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of machinable materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for clean cutting without coating buildup in fine tolerances\u003c\/li\u003e\n\u003cli\u003e4 straight flutes with right-hand cutting direction for smooth, controlled stock removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for reliable chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eCompact 2-3\/8-inch overall length suits short-reach and small-component applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill press chucks, collet holders, and CNC tool holders accepting a straight-cylindrical shank at wire size 39 diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of chucking reamers is performed by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation, and ensure the workpiece is rigidly fixtured to prevent movement during reaming. Always pre-drill the hole to the appropriate undersize before reaming, and apply cutting fluid suited to the workpiece material to extend tool life and improve surface finish. Do not use this reamer as a drill or attempt to use it freehand.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 (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\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 72290398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744581583154,"sku":"72290398","price":52.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fde7dad717d2d818e16cebf163b35705_525dbaf3-e04a-4e4d-aa58-9bb135fabc87.jpg?v=1788858585","url":"https:\/\/voomisupply.com\/products\/hertel-72290398-chucking-reamer-wire-size-39-0-0995-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
