SCIENTIFIC CUTTING TOOLS, Carbide, Bright (Uncoated), Thread Mill - 4PEV8|TM280-27NPTF - Grainger

These straight-flute thread mills have a bright finish that provides a smooth, polished surface. They are suitable for general purpose applications at slower speeds in nonferrous materials. Carbide thread mills offer excellent wear resistance, heat resistance, and hardness. Straight-flute thread mills are suitable for general purpose thread-milling applications. They provide good strength but require a rigid machine setup. Straight-flute thread mills create threads of the same pitch in a range of hole diameters, eliminating the need to change tools when threading multiple holes of different sizes. Thread mills are only usable in CNC machines that have helical interpolation capability. This listing is for each.
