The core-drilling bit is hollow at its center, just as the drill rods are. The outer rim of the drill bit consists of a cutting material, typically industrial-grade diamonds, embedded in a matrix. Variations in the hardness of the cutting material and matrix allow drilling crews to adapt their drill stem to the unique drilling condition of their site.
Drill crews can extract this sample from drill stem by retracting the complete drill string from the bore hole. But removing the sample that way brings drilling to a halt as the drilling crew raises the drill string to the surface.
