Abstract: Described herein is a cutting apparatus (100) for allowing visual inspection of a core sample in an inner tube at a drilling site after the inner tube has been removed from a coring tube and prior to it being transported to a laboratory. The cutting apparatus (100) comprises a support track (110, 112, 114, 116)) on which is mounted a tube support member (120), a cutter wagon (130, 132, 138) and a drive arrangement (140, 142, 144, 146). The apparatus (100) provides relative movement between an inner tube (150) and the cutter wagon (130, 132, 138) to allow a section of the inner tube (150) to be removed along its entire length for visual inspection. The drive arrangement (140, 142, 144, 146) provides the relative movement between the inner tube (150) and the cutter wagon (130, 132, 138).
