Built from micrograin solid carbide with an AlTiN coating, it delivers extended tool life and heat resistance during demanding cutting operations. The cutter measures 0.25 inches in diameter with a cutting width of 5\/64 inches (0.0781 inches) and runs on a 1\/4-inch shank. Its straight tooth configuration and 6-tooth design produce clean, accurate keyseat profiles. Machinists and toolroom professionals working in job shops, maintenance facilities, and production environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis keyseat cutter is suited for use on CNC machining centers and manual milling machines where precise keyseat slots are required. It is intended for cutting into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The compact neck diameter of 0.07 inches and neck length of 0.125 inches allow access to close-tolerance keyseat locations. Overall tool length is 2.5 inches, providing adequate reach for most standard shaft and bore configurations encountered in production and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal protection and extends tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eStraight tooth configuration for consistent keyseat profile accuracy\u003c\/li\u003e\n  \u003cli\u003e6-flute design balances chip clearance with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e0.07-inch neck diameter enables access to tight keyseat locations\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-inch shank toolholders on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is powered down before loading or removing the cutter from the toolholder. Verify shank seating and toolholder runout before cutting, as excess runout accelerates wear on carbide tools. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting speeds, feeds, and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.0781 inches (5\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.125 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: 6\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, Micrograin Grade\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: INTERNAL TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57-1040-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67910724452658,"sku":"57-1040-C","price":96.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f57728f2ff580247baaf6e8d21624533.jpg?v=1791199921","url":"https:\/\/voomisupply.com\/products\/internal-tool-57-1040-c-woodruff-keyseat-cutter-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
