Polycrystalline Diamond (PCD) is considerably harder and wear resistant than tungsten carbide enabling tremendous longer tool life. However, due to the brittleness of the PCD, the cutting edge geometry of a PCD saw blades is less aggressive compared to a that of a Tungsten Carbide Tipped saw blade. In result, the cut quality is inferior to that of a T.C.T. saw blade.
 
We have developed a V-shaped rake side tooth geometry for PCD tipped saw blades, which cuts aggressive like a T.C.T. saw blade. In result the tool life is 30 to 40 times longer and the saw blades cuts tear out free laminated particleboard or MDF.

In order to manufacture such a tooth shape, it was necessary to invent a technology that allows fusing single PCD elements together. After years of research, we have successfully developed this technology. The first product available with two single pieces of PCD fused into a V-shaped tip is the V-tech PCD saw blade.
