Built to Series I4S specifications, it features a 1\/2 inch cutting diameter, 1 inch length of cut, and a 4-flute right-hand helical geometry with a 30-degree helix angle. The TiAlN coating provides thermal resistance and extended tool life when cutting at elevated speeds. With a 3 inch overall length and a 1\/2 inch straight-cylindrical shank, it mounts directly into standard end mill holders or collet chucks. This tool is center-cutting, allowing direct plunging into workpieces where the operation requires it.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials in both roughing and finishing passes. It is a single-end, regular-length tool appropriate for vertical machining centers, horizontal mills, and manual knee mills where rigidity and runout control are maintained. Machinists and CNC operators working in job shops, aerospace, and general metalworking will find it applicable across a broad range of ISO material groups including P, M, K, N, S, and H classifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for thermal protection and extended tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical design with a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/2 inch shank for compatibility with standard toolholders\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series I4S OEM-style solid carbide square end mill suitable for standard 1\/2 inch end mill holders and ER collet chucks used in CNC and manual milling applications across ISO material groups P, M, K, N, S, and H.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set screw is torqued according to the toolholder manufacturer specifications.
