As shown in the figure, the diamonds are scattered throughout the matrix, and the action relies on the matrix to slowly wear during the drilling process, so as to expose more diamonds. The bit is mounted onto a core barrel which is attached to the drill string, which is connected to a rotary drill rig.
The diamonds are dispersed throughout the matrix, and the action depends on the matrix wearing down gradually during drilling to expose more diamonds. The drill bit is attached to a core barrel that is connected to a drill string, which is then linked to a rotary drill rig.
