As we all know, diamond is the hardest materials in the world. And it can be formed various types, such as SCD Diamond, CVD Diamond and PCD Tools. The difference between single diamond tools, cvd diamond tools and pcd tools are as following tables:

From above tablet, we can see that PCD Tools are the most suitable materials for machining aluminum alloy, other metals (such as copper, Brass, Bronze) and some other composites with high abrasive resistance, such as graphite, CFRP, Polyurethane, ect.
SCD Diamond Tools are mostly used for some high precision process, which can help obtain high size precision and surface roughness. CVD Diamond Tools and PCD Tools can be used for many similar field, however PCD Tools are better for roughing process and some high requirements situations . CVD Diamond Tools are better for finish, semi-finishing process, because it has excellent abrasive resistance and high hardness.
