The plane density of diamond on the working layer of the tool head matrix is related to the strength of thediamond segments cuspate top turbo shape of drill bits,matrix encapsulating diamond, the size and concentration of the diamond selected by the tool head. The higher the concentration of diamond selected by the tool head, the higher the average density of diamond on the working surface of the tool head matrix, the higher the wear resistance of the tool head, and the longer the service life of the tool head.
The higher the longitudinal density of diamond in the working layer, the more layers of diamond in the working layer, the more layers of diamond in the working layer, anddiamond segments of small diameter drill bitsthe longer the service life of the tool.
The diamond longitudinal density of the working layer on the matrix of the tool head is related to the size and concentration of the diamond selected by the tool head. The higher the concentration of diamond, the higher the longitudinal density of diamond in the working layer of the tool head matrix and the more diamond layers in the tool head matrix.
