With a 0.25-inch diameter and a 2.0-inch length of cut, it handles both roughing and finishing passes in a single setup. The 40-degree helix angle promotes aggressive chip evacuation, while the Zplus PVD coating protects the cutting edge and reduces built-up edge when machining soft, gummy materials. A 0.125-inch nose radius defines the ball profile. This tool is intended for use by machinists and CNC operators working in job shop, production, or aerospace environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for 3-axis and multi-axis CNC machining centers running aluminum, brass, copper, and other non-ferrous metals. The long-reach geometry, with a 2.0-inch reach length on a 4.0-inch overall length tool, allows access to deeper pockets and cavities without sacrificing rigidity. The straight cylindrical shank fits standard collet and end mill holders. It is cataloged in the Helical Solutions 3 Flute Ball 40 Degree Helix Variable Pitch series, which is engineered specifically for non-ferrous material removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute variable pitch geometry reduces harmonic vibration during cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating extends tool life and reduces friction against non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBall nose profile with 0.125-inch nose radius enables 3D contouring and finishing passes\u003c\/li\u003e\n  \u003cli\u003eLong-reach configuration with 2.0-inch LOC on a 4.0-inch overall length\u003c\/li\u003e\n  \u003cli\u003eSuitable for both roughing and finishing operations in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining aluminum alloys and non-ferrous metals.
