The Koller Core Saw is used to cut the inner tube with drill core into 900 – 1,000 mm sections. The conical drums of the connected lay down frame feeds the inner tube to the saw, where an air-powered diamond or corundum saw blade cuts it into the sections described above.
The inner tubes can be made of aluminum alloy, fibreglass or heat-treatable steel. In most cases, aluminum tubes are used, so the equipment is optimised to effectively cut filled-core aluminium tubes.
The core saw is suitable for offshore and onshore applications.
