Hence, Diamond is the hardest material on the earth. Polycrystalline Diamond (PCD) tools are manufactured at a high-temperature and high-pressure laboratory that fuse diamond particles onto a carbide substrate which allows the diamond to be brazed onto a tool’s body.

If you’re looking for the ultimate in tooling you’ve found it! As a matter of fact, PCD-tipped 60-degree engraving V-grooving and chamfering CNC router bits will groove a wide variety of tough abrasive materials including composites particleboard MDF (both raw or with melamine) veneer, and hardwoods. While this is true, the cutting edges last much longer than carbide for an extremely long life.
