The TiAlN coating on these straight-flute thread mills withstands high temperatures and protects the thread mills from wear when milling hard materials. The TiAlN coating allows the thread mills to be used at faster speeds than thread mills with a bright finish. 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.
