Helical Flute Thread Mill: 3/8-32, Internal, 4 Flute, 5/16" Shank Dia, Solid Carbide MPN:TMI285-32H

The Helical Flute Thread Mill: 3/8-32, Internal, 4 Flute, 5/16 Shank Dia, Solid Carbide is a scientific cutting tool designed for precise internal threading applications in metals, plastics, and composites. Made from durable solid carbide, it offers exceptional resistance to wear, vibration, and heat while maintaining its sharpness over prolonged usage. Its unique helical flute design produces smoother surfaces, reduced chatter marks, and increased chip evacuation compared to conventional end mills. The four flutes enhance thread quality by providing clearance in the corner radii and minimizing load on the cutting edge. It is ideal for applications requiring exacting tolerances such as gears, fasteners, and other components used in aerospace, automotive, medical devices, and hardware manufacturing industries.
