It is designed for precision hole finishing in metalworking and machining applications. The four-flute straight configuration and bright uncoated carbide construction deliver consistent sizing and smooth finish on through-holes and blind bores. With an overall length of 1.5 inches and a flute length of 0.25 inches, this is a compact tool built for small-diameter reaming where tight tolerances are required. It features a straight cylindrical shank for use in standard chucks and collets on drill presses, lathes, and CNC machining centers. Diameter tolerance is held to 0.0000 to 0.0002 inches, making it suitable for close-fit bore work.\u003c\/p\u003e\n\u003cp\u003eThis reamer is used in precision machining environments where wire gauge sized holes must be brought to final dimension with repeatable accuracy. It is a right-hand cutting tool appropriate for ferrous and non-ferrous materials where solid carbide tooling is preferred over high-speed steel for wear resistance and edge retention. Typical applications include fixture work, instrument manufacturing, and component production requiring controlled bore diameters in the sub-0.05-inch range. Machinists and tool-and-die professionals will find this tool suitable for both production and maintenance machining work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eWire gauge size 61 with 0.0390 inch decimal diameter\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes for smooth cutting and consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0000 to 0.0002 inches for precision bore sizing\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and machine spindles accepting straight cylindrical shanks in the appropriate diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists on drill presses, lathes, or CNC machining centers. Secure the shank firmly in a collet or drill chuck before use and verify runout is within acceptable limits for the required bore tolerance. Ensure the workpiece is securely clamped and the hole has been pre-drilled to the appropriate undersize before reaming. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: 61\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.25 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 79890943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734050406706,"sku":"79890943","price":54.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204bbc54ec3e71c9cc49025b8cb50413.jpg?v=1788760677","url":"https:\/\/voomisupply.com\/products\/hertel-79890943-chucking-reamer-wire-61-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
