Micro 100 TM-312-24X Carbide UN Thread Mill - High Performance Helical Thread Milling Tool for Precision Machining | Ideal for CNC, Metalworking & Industrial Applications

These helical-flute thread mills have an AlTiN coating that provides better resistance to abrasion and high heat than a TiAlN coating. AlTiN-coated thread mills are used for milling hard and abrasive materials. Carbide thread mills offer excellent wear resistance, heat resistance, and hardness. Helical-flute thread mills have spiral flutes that distribute the chip load as the thread mill removes material to cut threads into an existing hole or onto the external surface of a part. They provide a smoother cut than straight-flute or single-profile thread mills and are used to create threads on tough or thin-walled materials. Helical-flute thread mills can create internal 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.
