It features a 3\/8-inch mill diameter, a 0.09-inch corner radius, and a 3-flute, single-end configuration with a variable-pitch, high-helix geometry. Applied with a Zplus PVD coating, this tool is optimized for aluminum and non-ferrous metals as its primary workpiece materials, while also handling steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The centercutting design and right-hand flute direction make it suitable for plunge and conventional milling operations. It is installed and used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for both roughing and finishing passes, making it a versatile choice on CNC machining centers. The extended-reach design, with a 2.125-inch reach length, allows access in deeper cavities without sacrificing rigidity. The straight-cylindrical shank fits standard high-precision toolholders. Its medium-length flute classification and helical flute type support efficient chip evacuation, which is especially critical when cutting aluminum and other gummy non-ferrous materials at elevated feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with Zplus PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eVariable-pitch design reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.09-inch corner radius with a tight tolerance of -0.002 to 0.002 inches for consistent part geometry\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 2.125 inches supports deep-cavity and difficult-access milling\u003c\/li\u003e\n  \u003cli\u003eCompatible with high-precision toolholders; maximum TIR of 0.0003 inches ensures runout control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the H40ALV-RN-3 series.
