Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as stone and ceramics. Diamond saw blade mainly consists of two parts: matrix and cutter head. The matrix is the main supporting part of the bonded cutter head, while the cutter head is the cutting part during use. The cutter head will be consumed continuously during use, while the matrix will not, the reason why the cutter head can play the role of cutting is that it contains Diamond. As the hardest material at present, Diamond friction cuts the processed object in the cutter head. While diamond particles are wrapped inside the cutter head by metal.
