The tool features a 0.25-inch cutting diameter, a 0.0100-inch corner radius, and three right-hand spiral flutes with a 40-degree high helix angle. The single-end, centercutting design allows plunge entry and controlled material removal. At 2.5 inches overall length with a 0.3125-inch length of cut, this is a stub-length tool built for rigidity and accuracy in close-tolerance work. It is installed by machinists and CNC tooling technicians operating vertical or horizontal milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on non-ferrous metal workpieces including aluminum, brass, copper, and similar materials. The AN340 series stub configuration provides extended reach via a 0.75-inch reach length and a reduced 0.24-inch neck diameter, allowing access to recessed features without sacrificing tool stiffness. The bright, uncoated finish is well-suited for non-ferrous applications where coating buildup or thermal considerations are a concern. It mounts in standard straight-bore toolholders accepting a 0.25-inch shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous milling\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius with tolerance of plus 0.00100 to minus 0.00100 inches\u003c\/li\u003e\n  \u003cli\u003eThree right-hand flutes with 40-degree high helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.24 inches enables access to recessed or undercut features\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish optimized for non-ferrous metal applications\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, stub-length geometry suited for both roughing and finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 0.25-inch cylindrical shank.
