The TiAlN coating on these single-profile 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. Single-profile thread mills create very low side-cutting pressure and provide more control over the pitch diameter and cut length during thread-milling tasks than helical-flute or straight-flute thread mills. They are used to cut threads into an existing hole or onto the external surface of a part in applications with unfavorable length-to-diameter ratios. Single-profile thread mills can create internal threads with a variety of pitch ranges, lengths, and diameters. This eliminates 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.
