Built on GWS Series 2213, this single-end tool features a 1.25-inch mill diameter, a 1.5-inch length of cut, and 5 flutes with a 38-degree helix angle for efficient chip evacuation. The AlCrO-MAX coating provides excellent wear resistance and thermal stability, making it well-suited for extended production runs. Submicron carbide grade construction delivers the rigidity needed to maintain dimensional accuracy in aggressive cutting conditions. A licensed machinist or CNC tooling specialist typically selects and installs this end mill.\u003c\/p\u003e\n\u003cp\u003eThe GWS 312487 is suited for milling ferrous alloys, cast iron, stainless steel, non-ferrous metals, heat-resistant superalloys, and plastics, corresponding to ISO workpiece material codes H, K, M, N, P, and S. The chipbreaker geometry helps manage chip load when machining at higher feed rates. The 5-inch overall length and right-hand cutting direction make this a standard fit for vertical and horizontal CNC machining centers as well as manual knee mills requiring a 1.25-inch shank tool in the spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrO-MAX coating for superior heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e5-flute, 38-degree variable-free helix for smooth chip flow and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry to control chip load at elevated feed rates\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling entry\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 1.25-inch shank diameter with h6 shank tolerance.
