Built from solid carbide with a micrograin grade substrate, it carries an AlTiN finish that extends tool life in high-heat cutting environments. The cutter measures 7\/16 inches in diameter with a 7\/8 inch length of cut, mounted on a 1\/2 inch shank, and runs an overall length of 4 inches. Two spiral flutes at a 40-degree helix angle promote efficient chip evacuation and reduce cutting forces. This tool is centercutting, allowing plunge entry without a pre-drilled hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations in job shops, tool rooms, and production machining environments handling ferrous and non-ferrous materials. The AlTiN coating makes it a strong choice for dry or semi-dry cutting of hardened steels and stainless alloys where heat resistance is critical. The double-end configuration provides two usable cutting ends, extending the service interval before replacement. It is sized for use in standard milling machines, machining centers, and CNC routers accepting a 1\/2 inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature and hard-material cutting performance\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e40-degree helix spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production-grade cutting tool for milling machines and CNC machining centers equipped with a 1\/2 inch collet, ER chuck, or end mill holder accepting a 1\/2 inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator.
