Built from micrograin solid carbide and finished with a ZrN (zirconium nitride) PVD coating, this tool delivers consistent cutting performance in aluminum, brass, copper, and similar workpiece materials. The 1\/2-inch mill diameter pairs with a 1-inch length of cut and a 0.030-inch corner radius, producing a controlled edge break that reduces chipping at part corners. A variable helix flute geometry minimizes chatter and vibration during roughing passes. This tool is installed by machinists and CNC programmers working in job shops, production facilities, and aerospace or automotive contract manufacturing environments.\u003c\/p\u003e\u003cp\u003eThe US362052 is suited for roughing operations on non-ferrous metal workpieces where a corner radius profile is required to meet part geometry or reduce stress concentrations at shoulder transitions. The short-length flute design provides rigidity in standard depth-of-cut applications. The straight cylindrical shank measures 1\/4 inch in diameter and seats directly into a compatible toolholder. The coarse pitch and three-flute configuration support aggressive chip evacuation without recutting, which is critical when working aluminum or other gummy non-ferrous alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eZrN PVD coating optimized for non-ferrous metal cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix geometry reduces harmonic vibration during roughing\u003c\/li\u003e\n\u003cli\u003e0.030-inch corner radius with a tolerance of -0.0010 to +0.0010 inches\u003c\/li\u003e\n\u003cli\u003eCentercutting capable  -  supports plunge entries\u003c\/li\u003e\n\u003cli\u003eCoarse pitch, three-flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 1\/4-inch shank diameter.
