It features a 0.5-inch cut diameter, a 0.047-inch cut width, and an AlTiN coating that extends tool life in ferrous and hard materials. The straight-tooth configuration delivers clean, accurate slot geometry. With an overall length of 3 inches and a 0.5-inch shank diameter, it mounts directly in standard end mill holders or collet chucks. This cutter is sized for precision work and is typically installed by machinists and tool-and-die professionals running CNC or manual mills.\u003c\/p\u003e\u003cp\u003eThis cutter is suited for keyseat operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The AlTiN finish makes it a practical choice for high-heat applications where HSS tooling would wear prematurely. The 0.25-inch neck diameter and 0.75-inch neck length provide clearance for reach into deeper slot locations without sacrificing rigidity. Typical applications include shaft keyway milling in mechanical assemblies, power transmission components, and precision machined parts where tight dimensional tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e0.047-inch cut width produces accurate keyseat slots per Woodruff key standards\u003c\/li\u003e\n\u003cli\u003e8 straight teeth deliver clean slot geometry and consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.25-inch neck diameter with 0.75-inch neck length provides reach clearance\u003c\/li\u003e\n\u003cli\u003e0.01-inch corner radius reduces stress concentration at slot corners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2-inch shank end mill holders or collet chucks on CNC machining centers and manual knee mills.

Secure the shank fully in the holder to the recommended gauge-line depth before cutting. Ensure the machine spindle is fully stopped and the machine is powered down before changing or inspecting the cutter. Carbide tooling is brittle — avoid impact loading or dropping, and confirm feed and speed parameters are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Width\u003c\/strong\u003e: 0.047 inches (1.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: 987720-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727479111986,"sku":"987720-C3","price":229.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b38f801891c5254d9a60aee7b5261ebc.jpg?v=1788678369","url":"https:\/\/voomisupply.com\/products\/harvey-tool-987720-c3-woodruff-keyseat-cutter-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
