Radius Endmill for Exotic Alloys SSEH Type Series
I
SSEH Type Radius ■ Features and Applications ● Steep helix (45° helix) improves sharpness
● Combination of unique flute design and semi-mirrored rake face improves chip evacuation and adhesion resistance. ● Ultra-smooth coating with improved hardness and thermal resistance combined with tough carbide substrate improves tool life when working with heat-resistant alloys. ● Unique, smooth radius shape mitigates cutting impact and improves fracture resistance. ● Both coated and uncoated types are in stock to meet various conditions.
■ Application Examples
● Inconel 718 (Side Milling)
● Inconel 713 (Side Milling)

In Sumitomo Electric Hardmetal tests, the special coating with excellent adhesion
resistance provided less cutting edge adhesion than the competitor ’ s product and enabled fracture-free machining. The competitor ’ s product suffered from edge adhesion leading to breakage.
