Manufactured in the USA, this solid carbide end mill is designed for high-performance milling operations where heat resistance, tool life, and surface finish quality are priorities. The AlTiN coating extends cutting life in ferrous and hard materials by reducing friction and improving thermal stability at the cutting edge. It is a standard single-end geometry suited for profiling, slotting, and contouring operations on CNC and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in machine shops, tool rooms, and production environments handling ferrous metals, stainless steels, cast iron, and hardened materials. The 4-flute configuration supports smoother finishes and faster feed rates compared to 2-flute designs, making it a practical choice for finishing passes and side milling. It is typically installed and used by machinists, CNC operators, and toolmakers working in aerospace, automotive, medical, and general precision machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch cutting diameter with matching 3\/16 inch shank for direct collet or end mill holder fitment\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry for improved surface finish and higher feed rate capability\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides elevated heat and oxidation resistance for extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eCenter cutting design allows plunge milling in addition to peripheral and slot milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under aggressive cutting conditions\u003c\/li\u003e\n  \u003cli\u003eMade in the USA to consistent manufacturing tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end carbide end mill for use in ER collet chucks, end mill holders, and similar toolholding systems accepting a 3\/16 inch straight shank on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the full recommended insertion depth in the collet or holder and torque the retention nut per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use and verify runout with a dial indicator when tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Aluminum Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Center Cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.42 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TDD50-4012S-ALT-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51234023407922,"sku":"TDD50-4012S-ALT-D","price":24.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307624841.png?v=1780115360","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-tdd50-4012s-alt-d-4-flute-altin-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
