It features a 0.3125-inch cutting diameter and a 0.078-inch cutting width, making it suited for precise, narrow slot work. The straight-tooth configuration provides clean, controlled cuts in a wide range of workpiece materials. An AlTiN (aluminum titanium nitride) coating improves heat and wear resistance, extending tool life in demanding milling applications. With a 5\/16-inch shank diameter and a 2.5-inch overall length, the cutter mounts directly into standard milling machine collets or tool holders. This tool is used by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\n\u003cp\u003eThe 69740-C3 is suited for keyseat milling in both ferrous and non-ferrous metals where tight dimensional tolerances are required. Typical applications include shaft keyway machining in job shops, maintenance and repair operations, and production milling environments. The 6-tooth straight configuration is well matched to conventional milling passes on knee mills and CNC machining centers. The AlTiN finish supports dry or minimal-coolant cutting strategies in harder workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.3125-inch cutting diameter for precise keyseat and slot milling\u003c\/li\u003e\n  \u003cli\u003e0.078-inch cutting width for narrow, accurate slot profiles\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances heat resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003e6 straight teeth for controlled chip formation and clean slot walls\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount keyseat cutter for use in standard milling machine collets and tool holders accepting a 5\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Secure the shank fully in a clean, appropriate-sized collet or end mill holder and verify runout before cutting. Ensure the machine spindle is fully stopped before installing or removing the cutter. Follow your machine manufacturer guidelines for speed and feed settings appropriate to the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Configuration\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69740-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51753806856498,"sku":"69740-C3","price":158.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f89b291ee5f8fd0b5931f6eac09276a_f21e014a-e0ba-45c8-91d9-9146b1faf1ef.jpg?v=1788940861","url":"https:\/\/voomisupply.com\/products\/harvey-tool-69740-c3-woodruff-keyseat-cutter-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
