It features a 0.375 inch cutter diameter with a 0.04 inch cutting width and mounts on a 3\/8 inch straight shank. Eight straight teeth provide clean, repeatable cuts in a single radial pass. The AlTiN coating increases surface hardness and heat resistance, extending tool life in demanding cutting conditions. With a 2.5 inch overall length and a 0.125 inch neck diameter, the tool provides the clearance needed to reach keyseat depths without interference from the shank body. This cutter is sized for the No. 204 Woodruff key standard.\u003c\/p\u003e\n\u003cp\u003eThis keyseat cutter is suited for manual mills, CNC machining centers, and knee mills where shaft keyways must be cut to close tolerances. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary applications extend to non-ferrous metals, superalloys, titanium, and hard materials. Machinists and toolroom operators will find this tool appropriate for production and prototype work requiring consistent keyseat geometry across multiple parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.375 inch cutter diameter with 0.04 inch cutting width for No. 204 Woodruff key profile\u003c\/li\u003e\n  \u003cli\u003eEight straight teeth deliver smooth, stable radial cutting action\u003c\/li\u003e\n  \u003cli\u003e0.125 inch neck diameter provides clearance for deep or close-tolerance keyseat applications\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch straight shank compatible with standard collet systems and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard addition for machining setups requiring a No. 204 Woodruff keyseat profile. Compatible with any milling machine spindle accepting a 3\/8 inch straight shank via collet or end mill holder.

Ensure the spindle and workpiece are fully secured and the machine is at a complete stop before tool changes. Run at manufacturer-recommended surface footage for carbide tooling in the target workpiece material, and avoid climb milling on manual machines without backlash compensation. Inspect the cutting edges before each use — carbide is brittle and chipped teeth will produce out-of-tolerance keyseats.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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\u003eNeck Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.187 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\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: 0.14 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: 71115-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730019615026,"sku":"71115-C3","price":165.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f8260aff7fcbf035c65a387295d7d88_c4115816-3544-4f2f-8a79-65260da50214.jpg?v=1788710303","url":"https:\/\/voomisupply.com\/products\/harvey-tool-71115-c3-woodruff-keyseat-cutter-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
