■ Features and Applications ● Two different types of flute shapes are available. SSDC Type (Right-hand Helix Type) Achieving both better sharpness and longer tool life through

optimizing the rake and relief angles, along with a small helix angle.

I

SSDCRL Type (Right/Left-hand Helix Type) Right/left-hand helix prevents delamination on top and bottom surfaces. Cutting force is dispersed even with unstable clamping, improving surface quality.
