It features a 1\/2 inch cutting diameter, a 0.015 inch corner radius, and four flutes arranged in a right-hand spiral with a medium helix for efficient chip evacuation. The CVD diamond coating provides exceptional hardness and wear resistance, making it well suited for abrasive workpiece materials that would rapidly wear uncoated carbide. At 6 inches overall length with a 1\/2 inch straight-cylindrical shank, this single-end, centercutting tool handles both roughing and finishing operations in one setup. Licensed machinists and CNC operators install this tool in compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for use in applications involving non-ferrous metals such as aluminum, copper, and brass, as well as graphite and composite materials. The extended reach design, with a 1.5 inch reach length and 0.475 inch neck diameter, allows access to deeper features or stepped pockets while maintaining rigidity. Its stub-length flute geometry at 1\/2 inch length of cut keeps deflection low during aggressive cuts. It is suited for CNC milling centers running right-hand cutting operations with standard toolholder setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD diamond coating for superior wear resistance in abrasive and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentrations and extends tool life at part edges\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1.5 inch reach length and reduced 0.475 inch neck diameter for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle operation\u003c\/li\u003e\n  \u003cli\u003eHandles both roughing and finishing material removal types in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard CNC milling toolholders accepting a 1\/2 inch straight-cylindrical shank.
