It features a 0.75 inch mill diameter, a 2.25 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN coating provides high surface hardness and reduced friction, making this tool well-suited for cutting ferrous and non-ferrous alloys. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting action. Machinists and toolroom professionals are the primary users of this tool in CNC vertical and horizontal milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for long-reach roughing and finishing passes where a standard-length tool cannot reach. The 5 inch overall length and 0.75 inch shank diameter support rigid setups in deep-cavity milling, die and mold work, and profile machining. The micrograin carbide substrate maintains edge integrity at elevated spindle speeds and feeds. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03 inch corner radius reduces edge chipping and stress on workpiece corners\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for increased surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for consistent edge retention\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cutting with long-length classification for deep-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC milling machines and machining centers accepting a 0.75 inch round shank.
