The compound neck shape with results proven by the Epoch Deep Series is used. Breakage resistance is improved even for endmills with long below-neck lengths, so that stable deep machining can be performed.

The flute cross-section is the oval shape with results proven by Epoch Turbo Mills.
It suppresses vibrations, particularly when machining corner areas, so that stable high-efficient cutting can be performed.

The corner R flute shape is the same chipping-resistant, high-rigidity flute type that is used the the Epoch Turbo Mills. Machining with high per-flute feed amounts is possible and increases machining efficiency.

• A newly developed nanocomposite coating material is able to withstand high cutting temperatures.
  Through the use of a new structure made up of nanocrystal material, a higher hardness of coating is achieved.
• Enables high-quality machining with long life of hardened steel
  (45 to 65HRC), pre-hardened steel, etc.
