As a core , a cylindrical body is referred to, with the aid of a core drilling of rock , building materials or structures is removed. In this way, either round openings can be created or test specimens can be obtained. In particular when monitoring the quality of concrete and asphalt , drill cores are often produced in order to be able to assess the quality of the building material. For example, in addition to the layer thickness, the binder content, the grain distribution and the void content can also be determined on the asphalt core.

In the climate research are ice cores used for the analysis of past climatological conditions.
