Diamond saw is a cutting disc, widely used in the machining of hard and brittle materials such as stone, ceramic. Diamond saw blade is mainly composed of two parts,  the base body and the head. The substrate is the main support portion of the bonding tip, while the tip is in the use of the process from the cutting portion abrasive tools, the tip will be in use constantly consumed, while the matrix is ​​not, the tip is able to from cutting is the role of as the hardest substance because it contains the diamond, diamond cutting the object to be processed, it is the tip friction. The diamond particles by metal wrapped inside the tip. During use, the metal carcass and diamond consumption generally more desirable situation is that the consumption of metal carcass faster than adamantyl, both to ensure the sharpness of the tip and can ensure that the tip has a longer life.
