  • Characteristics and Applications
  • Characteristics and Applications
  • High helix (45° helix) improves sharpness.
  • New anti-vibration type added to the SSEH type endmill for exotic alloys.
  • Combination of unique flute design and semi-mirrored surface

Builds on the same features of existing endmills by adding an irregular lead for exceptionally good anti-vibration performance.

improves chip evacuation and adhesion resistance. Compatible with wide range of milling for exotic alloys including SUS, Inconel, and Titanium.

  • Ultra-smooth coating with improved hardness and

Reduces chattering for high-speed, high-feed cutting.

heat resistance combined with tough carbide substrate

Both coated and uncoated types are available in stock to meet various conditions. improves tool life when working with heat resistant alloys.

  • Unique, smooth radius shape mitigates cutting impact and +

Irregular Pitch Irregular Lead improves fracture resistance.

  • Both coated and uncoated types are available in stock to meet various conditions.
