Primarily used in mining, oil and gas exploration and geotechnical engineering. Conventional Core Barrels are used to extract cylinder samples of rock sediment from a formation.

During the Drilling process the core barrel is lowered into the borehole and rotation is applied to the entire assembly. As the core bit or cutting shoe penetrates the subsurface, it cuts a cylindrical selection of rock or sediment. The core sample enters the inner tube and is collected within it.

Conventional core barrels are typically used in shallow to medium depth drilling applications and their design may vary depending on the specific requirement of the project.
