With a 0.5-inch cutter diameter and a 0.156-inch cutting width, this tool machines precise Woodruff key seats used in shaft-to-hub assemblies across a wide range of machining applications. The straight-tooth configuration and AlTiN coating provide thermal resistance and edge durability at elevated cutting speeds. With 8 teeth and a 0.5-inch shank diameter, the cutter fits standard toolholders and delivers consistent results in production and job-shop environments. A licensed machinist or CNC operator is the typical end user.\u003c\/p\u003e\n\u003cp\u003eThis cutter is suited for milling keyseat slots in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its 0.75-inch neck length provides clearance for slotting operations where the cutter must reach below a shoulder or step on a workpart. The 3-inch overall length accommodates standard spindle setups on vertical machining centers and manual knee mills. It is a solid choice for automotive, aerospace, and general precision machining applications where tight keyseat tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life when cutting steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e0.156-inch cutting width produces accurate Woodruff keyseat slots to standard key dimensions\u003c\/li\u003e\n  \u003cli\u003e8 straight teeth for consistent chip formation and smooth slot finish\u003c\/li\u003e\n  \u003cli\u003e0.25-inch neck diameter with 0.75-inch neck length provides clearance for deep or recessed slot entry\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius reduces stress concentration at slot corners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch shank toolholders on vertical machining centers, knee mills, and similar milling equipment.

Secure the shank fully in a collet or endmill holder to the recommended gauge line before operation — avoid excessive tool overhang beyond what the neck geometry requires. Verify spindle speed and feed rate against the manufacturer cutting data for the specific workpiece material before engaging the cut. Do not use this cutter for plunge milling; it is designed for peripheral keyseat slotting only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\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: 0.015 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\u003eConnection Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\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 and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: 990365-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51750519079218,"sku":"990365-C3","price":234.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b38f801891c5254d9a60aee7b5261ebc_6a23c47e-c700-4844-8946-10d7fe43c5a2.jpg?v=1788916118","url":"https:\/\/voomisupply.com\/products\/harvey-tool-990365-c3-woodruff-keyseat-cutter-0-5in-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
