It features a 1\/2 inch cutting diameter, a 0.03 inch corner radius, and 7 flutes with a right-hand spiral and right-hand cutting direction. The nACRo coating provides enhanced wear resistance and thermal stability, making it well-suited for harder workpiece materials. At 6 inches overall length with an extended reach design, this single-end, centercutting tool handles both plunge and lateral cutting operations. The micrograin carbide substrate delivers the edge retention needed for tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where a corner radius profile is required to reduce stress concentrations at part corners or produce blended fillets. The extended reach and reduced neck diameter of 0.47 inches allow access to deep pockets and stepped features. It is typically installed and operated by machinists and tool-and-die professionals working in job shop, aerospace, mold-and-die, or precision manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003enACRo coating for improved wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e7-flute geometry increases feed rate capability and improves surface finish\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eExtended reach with 3-1\/8 inch reach length for deep pocket and cavity work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment corner radius end mill for CNC machining centers and manual milling machines accepting a 1\/2 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists using an appropriate collet or end mill holder rated for the 1\/2 inch shank diameter.
