Metric Multitooth 30° Helical
Optimized for strength and stability, our Metric Multitooth 30° Helical Thread Mills feature a helical flute design that reduces side cutting pressure for smoother, more controlled internal threading. Crafted from premium submicron grade carbide, these tools are built for precision and longevity. The AlTiN⁺ coating enhances heat resistance and extends tool life, making them ideal for high-performance applications. Designed exclusively for internal threads, these thread mills deliver reliable, repeatable results across a wide range of materials.
