Core drill rig is a specialized equipment for geological exploration, mainly used to obtain complete samples of underground rocks (i.e. cores) for further geological analysis. Diamond drill bit is a crucial component in core drilling machines, with extremely high hardness and wear resistance, capable of effectively cutting various hard rocks.

The working principle of diamond drill bits is to use small diamond particles embedded on their surface to cut rocks. These diamond particles are fixed on the surface of the drill bit through a special process. When the drill bit rotates, the diamond particles can efficiently break the rock and form core samples.
