This group of products is used to cut cylindrical samples of geological formations.

The core bit is part of an overall drilling system that includes a reaming shell, a core retrieval device (core barrel assembly), the drill string (rods) and the drill rig itself.

Depending on the range of application, the cutting media on the core bit may take the form of synthetic diamond on the impregnated type, natural drill diamond on the surface-set type, synthetic geotechnical type shapes or tungsten-carbide particles or elements.
