    Drill StructureRotary and Wire Line Diamond DrillingCORE ExtractionApplicationsMajor Diamond CORE Drilling LocationsHealth and SafetyCompanies Involved in Diamond CORE DrillingSources and Further ReadingThe term diamond core drilling comes from the ‘diamond bit’ drill used during this process. This drill bit is made up of a group of small, industrial grade diamonds set into a metallic, soft matrix. As the ground is drilled this matrix will wear away and expose more diamonds. The diamond bit is then attached to a drill rod which measures to about 10 feet in length. More sections of pipe can be attached to the top of the drill rod, allowing greater depthSee more on azomining
