It features a 5\/16-inch cutting diameter, a 1\/2-inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides the hardness and edge retention needed for demanding applications. An AlTiN coating adds thermal resistance and surface hardness, extending tool life in ferrous and high-temperature alloy cuts. This tool is installed and used by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\n\u003cp\u003eThe SGS 31186 is suited for milling operations across a broad spectrum of workpiece materials, including cast iron, non-ferrous metals, stainless steel, titanium alloys, carbon steel, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. Its stub length classification makes it a preferred choice when rigidity and reduced deflection are priorities, such as in close-tolerance slotting, profiling, and peripheral milling. The double-end design extends usable tool life by providing two cutting ends per tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated thermal resistance and extended tool life in ferrous and exotic alloy cuts\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports plunge and ramp entry cuts\u003c\/li\u003e\n  \u003cli\u003eStub length classification maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC and manual milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-bore milling chucks, collet holders, and shrink-fit toolholders accepting a 5\/16-inch straight-cylindrical shank.
