Diamond Blades at a glance.
Diamond blades are made of diamond crystals, usually synthetic, a bonding system, usually a sintered metal powder, a segment, and a metal core.
Varying the type, quality, size and concentration of diamonds with a bonding matrix that is designed to provide, in addition to a medium to support the diamonds, a specific wear rate matched to the material being cut gives rise to an enormous selection of diamond blades for specific applications.
The bonding material is designed to wear away at a rate matched to the material being cut so as to expose more diamonds to grind that material away. Therefore, when cutting a dense hard material like porcelain tile, it is best to design a blade with a "soft" bond to wear quickly to expose more diamond. Conversely, when cutting soft abrasive material like asphalt one would design a "hard" bond to give the diamonds time to work.
These two opposing factors directly affect the two most important criteria in diamond blade quality, speed of cut vs. life of the diamond blade. First impressions of quality by users are the ease of and speed of cut. If this was the only consideration, manufacturers might just design "soft" bonded blades, however, the life of the blade will be greatly compromised. As a result manufacturers have responded by offering various quality levels of blades for the specific material being cut. Generally speaking the higher quality blade with provide a significantly longer working life when used in the proper application.
