Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, it handles aggressive cuts in hardened steels, stainless, and superalloys. The 0.5-inch mill diameter is paired with a 1.625-inch length of cut and a 4-inch overall length. A 38-degree helix angle and five-flute configuration improve chip evacuation and surface finish. Variable index flute spacing reduces chatter during high-speed operations. Center cutting geometry allows direct plunge entry without a pre-drilled hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production milling, die and mold work, and finish profiling where tight tolerances and surface quality are required. The 0.030-inch corner radius reduces stress concentration at the cutting edge and extends tool life when machining inside radii and pockets. Right-hand flute direction and right-hand cutting orientation make it compatible with standard CNC machining center setups. It is a single-quantity item appropriate for toolroom, job shop, and production floor applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating extends tool life in high-heat cutting conditions\u003c\/li\u003e\n\u003cli\u003eFive flutes with variable index reduce vibration and improve finish quality\u003c\/li\u003e\n\u003cli\u003e0.030-inch corner radius reduces edge chipping and stress concentration\u003c\/li\u003e\n\u003cli\u003eCenter cutting design enables direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for CNC machining centers and milling machines accepting a 0.5-inch straight shank tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Secure the 0.5-inch shank in a collet chuck or end mill holder rated for the intended spindle speed and cutting load. Verify runout with a dial indicator before production use.
