RobbJack Diamond PCD Composite Finishing Tool. Polycrystalline Diamond (PCD) is one of the hardest known substances. Its extreme wear duration and hardness makes it an ideal material to use when cutting difficult to machine materials. These solid carbide bodied tools have been tipped with PCD profiles, and are ideal when cutting materials such as composites, plastics, fiberglass, and some non-ferrous metals.
