Diamond core bits are used extensively for exploration purpose. The key technology in this kind of drilling is the bit itself. The cutting surface of these bits is made up of industrial diamonds scattered throughout a metallic matrix.
In this kind of drilling the diamond encrusted bit is mounted onto a drill stem, which is connected to a rotary drill. As the drilling progresses the gradual wear of the matrix causes more diamonds to get exposed. Diamonds are the hardest substance known to mankind. They are able to drill through hard rock with ease.
The drilling process produces a 'core' which once retrieved is used to examine the subsurface rock and soil conditions. The core is used for studying the conditions at depths where future drilling activities are likely to be conducted.
The purpose of the reaming shells is two-fold:
