Exploration diamond drilling differs from other geological drilling (such as ) in that a solid core is extracted from depth, for examination on the surface. The key technology of the diamond drill is the actual diamond bit itself. It is composed of industrial diamonds set into a soft metallic matrix. As shown in the figure, the diamonds are scattered throughout the mat.
[pdf] Rotary bits drill the formation using primarily two principles: 1. Rock removal by exceeding its shear strength and 2. Removal by exceeding the compressive strength. The broken rock is removed by rotary s.
