It features a 0.25-inch mill diameter, a 0.312-inch length of cut, and a 2-flute straight-flute geometry brazed with a polycrystalline diamond (PCD) coating applied via PVD process. The 0 degree helix angle and stub-length profile make this tool well-suited for applications where rigidity and surface finish are priorities. At 0.06 pounds, it is a compact, precision-ground carbide tool intended for use by machinists and tooling professionals working in CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is built for stub-length, extended-reach applications in CNC machining centers handling non-ferrous workpieces. The 0.75-inch reach length and 0.438-inch neck length allow access to stepped or recessed features without sacrificing rigidity. It is appropriate for both roughing and finishing passes on materials including aluminum, brass, copper, plastic, graphite, and carbon fiber composite. Right-hand cutting and right-hand flute direction are standard. It is not designed for ferrous metal cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolycrystalline diamond (PCD) coating via PVD process for extended tool life on abrasive non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0 degree helix angle with straight flute geometry for controlled chip evacuation in graphite and composite applications\u003c\/li\u003e\n  \u003cli\u003e0.75-inch reach length with extended-reach geometry for accessing recessed features\u003c\/li\u003e\n  \u003cli\u003eSingle-end ball nose profile with 0.125-inch nose radius for accurate radius profiling and contouring\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.25 inches for standard ER collet or end mill holder compatibility\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 use on non-ferrous metals, plastics, graphite, and carbon fiber in CNC milling applications.
