● The R tolerance range within 6 μm (our measured ratio) / shank diameter, tolerance h5 standard, has been adopted. The high quality tools with minimal quality variation
are suitable for high-precision 3-dimensional machining.
● It is designed to have a blade shape with an emphasis on rigidity thanks to the radius (R) model negative blade. It is suitable for machining heat-treated steel / high hardness steel.
● The seamless shape (blade mounted in one step from the peripheral blade to the rounded center) has a flat and smooth blade runout surface.
● The TS coating consisting of a nitride-based composite film with a fully crystalline structure means that it has a high oxidation resistance temperature and high hardness. It is ideal for high speed machining and dry machining of heat-treated / high hardness steel.
