It features a 0.375 inch cutting diameter, a 0.125 inch cutting width, and a 3\/8 inch shank diameter. The staggered tooth configuration — 8 teeth total — reduces cutting forces and improves chip evacuation compared to straight-tooth designs. An AlTiN (aluminum titanium nitride) coating extends tool life at elevated cutting temperatures. Overall length is 2.5 inches. This tool is installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 915860-C3 is suited for keyseat work in steel, stainless steel, and cast iron as primary workpiece materials. It also handles non-ferrous metals, superalloys, titanium, and hard materials as secondary applications. The neck diameter of 0.188 inches and neck length of 0.563 inches provide clearance for slot entry without interference from the shank. Typical applications include shaft keyway production in power transmission components, gearboxes, and precision mechanical assemblies where tight slot 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 ferrous and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high heat resistance and extended tool life in dry or minimal-coolant operations\u003c\/li\u003e\n  \u003cli\u003eStaggered tooth geometry with 8 teeth reduces cutting forces and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e0.188 inch neck diameter and 0.563 inch neck length deliver slot-entry clearance on deep or offset keyseats\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter for standard collet or end mill holder compatibility\u003c\/li\u003e\n  \u003cli\u003eNo Weldon flat — compatible with standard precision collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Secure the 3\/8 inch shank in a clean, properly sized collet or end mill holder and verify runout before cutting. Confirm workpiece is rigidly fixtured before engaging the cutter to prevent chatter and tool deflection. Follow shop-specific speeds and feeds for the workpiece material and coating type; consult the manufacturer cutting data for AlTiN-coated carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.563 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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Configuration\u003c\/strong\u003e: Staggered\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, 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: 915860-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737146491186,"sku":"915860-C3","price":205.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0cf4a71bc2b0784d27b46ab74eb1d85.jpg?v=1788784919","url":"https:\/\/voomisupply.com\/products\/harvey-tool-915860-c3-woodruff-keyseat-cutter-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
