It features a 0.625-inch cut diameter, a 0.25-inch cut width, and a straight-tooth configuration with 8 teeth for clean, accurate cuts. The cutter carries an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in demanding cutting conditions. With a 5\/8-inch shank diameter and a 3.5-inch overall length, it mounts directly in standard end mill holders or collet chucks. Machinists and tool-and-die professionals use this cutter on CNC mills and manual vertical mills when cutting keyways to Woodruff key standards.\u003c\/p\u003e\u003cp\u003eThis keyseat cutter is suited for keyseat operations in ferrous and non-ferrous metals as well as hardened materials where the AlTiN finish provides a thermal barrier. Typical applications include shaft keyseating on precision mechanical assemblies, drive components, and power transmission parts. The straight-tooth geometry produces a smooth bottom and sidewall finish in the keyseat pocket, making it appropriate for close-tolerance fits between keys and bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.625-inch cut diameter with 0.25-inch cut width for Woodruff keyseat geometry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for improved thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e8 straight teeth for consistent chip load and clean pocket finish\u003c\/li\u003e\n\u003cli\u003e5\/8-inch shank diameter fits standard collet chucks and end mill holders\u003c\/li\u003e\n\u003cli\u003e3.5-inch overall length provides reach for typical shaft keyseat depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount keyseat cutter for use in CNC machining centers and manual vertical mills with standard 5\/8-inch collet or end mill holder tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom professional. Secure the shank fully in the collet or end mill holder and verify runout before cutting. Confirm the machine spindle is fully stopped and the axis is locked before changing or inspecting the cutter. Follow shop-standard feeds and speeds for solid carbide tooling and the workpiece material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 8\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: 0.56 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 70980-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730100650290,"sku":"70980-C3","price":301.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f0243c0242b8aafbb6b0dc4c13c15b9_3d8540a6-59c3-4600-890e-f98e4d9f5373.jpg?v=1788711767","url":"https:\/\/voomisupply.com\/products\/harvey-tool-70980-c3-woodruff-keyseat-cutter-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
