K-GRAPHITE END MILLS

COGO셲 Own Coating Method (CVD Diamond Coating) High resistance and performance when to cut graphite multiple product Line.

DIAMOND Coated End Mills for Graphite CVD diamond is a binderless-pure crystal, delivering identical properties of single diamond crystal.
COGO is applying the lastest CVD coating technology which has no residual Stress at the interface for extending tool life.
