Straight Flute Thread Mill: 3/8-18, Internal, 4 Flutes, Solid Carbide MPN:GF173111.5766

The straight flute thread mill is an innovative tool designed for producing accurate and precision threads of 3/8 - 18 UNC internal profiles with superior surface finishes. Made from premium solid carbide, this mil offers exceptional durability and resilience against high cutting pressures for extended tool life. Its four flutes design promote efficient chip evacuation and reduce heat buildup, preventing damage to workpieces or material deformation during machining. The right-hand cut configuration ensures smooth, stable threads by allowing optimal thread depth engagement with even feed rates while minimizing vibration and chatter marks. Perfect for aerospace, automotive, medical, general manufacturing sectors where precision-fit internal threads are required in high quantity runs, reducing costs on multiple operations like reaming or tap drilling.
