Sintered beads are made by mixing diamond powder and metal powder, and then sintering on the bead base. The structure of this bead has a relatively uniform diamond distribution, and both upper and lower layers can be cut. Therefore, the product has a long life and strong cutting ability. This kind of high wear resistance, can cut granite and other stones, but brazing and electroplating products are expensive due to excessive consumption and short life. At present, they are mostly used for marble mining.
