It features a 0.625 inch diameter cutting profile with a 1.625 inch length of cut and a 3.5 inch overall length. Constructed from micrograin solid carbide and coated with zirconium nitride (ZrN), it delivers hard, wear-resistant cutting performance suitable for ferrous and non-ferrous materials. The 3-flute, right-hand spiral geometry combined with a 37-degree helix angle promotes efficient chip evacuation and smooth surface finishes. This tool is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and contouring applications where a ball nose geometry is required to produce contoured or radiused surfaces. The ZrN coating extends tool life in abrasive materials and reduces built-up edge. The 5\/8 inch shank diameter fits standard collet chucks and end mill holders common to vertical machining centers and CNC knee mills. It is a solid choice for medium-depth passes in steel, stainless, aluminum, and similar workpiece materials where a single-end carbide tool is appropriate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN (zirconium nitride) coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003e37-degree right-hand helix promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3-flute configuration balances chip clearance and surface finish\u003c\/li\u003e\n  \u003cli\u003eBall nose geometry for contouring and radiused surface milling\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill for 5\/8 inch collet chucks and end mill holders on standard vertical machining centers and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists using a compatible collet chuck or end mill holder sized for a 5\/8 inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating the tool in the holder.
