Endmills for CFRP SUMIDIA Coated SSDC Series For CFRP ■ Characteristics and Applications ● Two different types of flute shapes are available. SSDC Type (Right-hand Helix Type) Achieves both higher cutting performance and longer tool life through optimisation of rake angle and relief angle. SSDCRL Type (Righ/Left-hand Helix Type) I139 Right/left-hand helix prevents delamination on top and bottom surfaces. ■ Series Cutting resistance is dispersed even with unstable clamping, improving Type No. of Flutes Shape Diameter (mm) surface quality.
