Coating Series: Ni Coating(chemical & electroplated), Ti Coating, Cu Coating, other coated
 diamonds are available.
Characteristics: Coated metal can improve heat dissipation and reduce heat damage thus protect the diamond
 (decrease diamond carbonization when sintering at ultrahigh temperature).
             Roughen the diamond particle surface to enhance the mechanical retention between diamond and bonds.
             Thus, prolong diamond tool life finally.
