Built to Series HS specifications, it features a 3\/4-inch diameter, a 1-inch length of cut, and five flutes with a 38-degree helix angle. The AlTiCrN coating provides heat and wear resistance at elevated cutting temperatures, making this tool well-suited for hard materials and aggressive feed rates. Variable index flute spacing reduces chatter and improves surface finish. The single-end design and right-hand cutting direction are standard for general milling operations on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for professional machinists working on production and job-shop applications. It handles ferrous and hardened materials where thermal resistance and edge retention are priorities. The extended reach configuration, with a 3.375-inch reach length and 6-inch overall length on a 3\/4-inch shank, allows access to deeper pockets and shoulders without requiring specialty toolholders. Micrograin carbide construction supports tight tolerances and consistent performance across high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e5-flute design with variable index for reduced vibration and improved surface finish\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle optimized for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eExtended reach at 3.375 inches for deep pocket and shoulder milling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge stability and precision\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for Series HS solid carbide square end mills with a 3\/4-inch shank diameter.
