Why PCD?

As innovation continues to improve materials and manufacturing processes, it is necessary to also upgrade the tools used in today’s high-tech machines.  Polycrystalline Diamond (PCD) tools have exceptional wear resistance, high thermal conductivity, and an extremely low coefficient of friction. These tools can out perform carbide tools 50-100 times, reduce machine downtime, and increase the quality of your products.


PCD is therefore quickly replacing carbide as the premier non-ferrous cutting tool material.  When properly manufactured to the right specifications, by the right company, PCD tools are the most cost-effective choice. GenHam Diamond Tooling is dedicated to manufacturing  PCD and PCBN tools, whether new, retipped or resharpened. This allows us to provide you with the best product and service possible.
