It features a 0.8125-inch (13\/16 inch) ball nose diameter and is manufactured from M7 high speed steel, offering solid toughness and wear resistance in general-purpose machining environments. The 2-flute spiral configuration supports effective chip evacuation, and the 30-degree right-hand helix angle balances cutting efficiency with surface finish quality. This tool is intended for machinists and toolroom professionals working on manual or CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits a wide range of shop applications including die and mold work, pocket profiling, and contour milling on steel, aluminum, and similar materials. With a 2-inch length of cut and a 4.25-inch overall length paired with a 0.75-inch shank diameter, the GG99914213 fits standard ER or side-lock toolholders common in both manual bridgeport-style mills and CNC machining centers. It is appropriate for job shops, toolrooms, and maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.8125-inch ball nose diameter for accurate contouring and profiling cuts\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness in interrupted cuts and general-purpose use\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design promotes chip clearance in slotting and profiling operations\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix angle balances cutting forces and surface finish\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with standard cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 0.75-inch shank fits common toolholder styles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock ball end mill for milling machines accepting a 0.75-inch straight shank.
