WF Coring

The WF series is a range of components which produces 76,92 and 112mm cores suitable for soft to medium hard geology.

It comprises of a core barrel head, inner and outer tubes, extension tube, core lifter, reaming shell and core bit. Different types of lifters, reaming shells and core bits need to be selected according to the application and geology.

It uses a thin wall double tube core barrel used in combination with metric casing and is easily converted to a triplex system with the addition of a
coreliner for increased core recovery.



  • Geotechnical investigation
