Yamawa Z-PRO premium thread mill PRML 8.0U20

[Features]
This is a threading tool that uses the "Helkari feed" function. If the pitch is the same with a single thread, it is possible to process female threads with different diameters.
By adopting an oil hole for internal oil supply, it is possible to achieve stable female threads even with blind holes.
A unique blade shape that reduces cutting resistance enables excellent internal threads to be processed.
