Abstract
The method is for penetrating a casting through sensible overburden or sensible structures. It uses a drill operated by compressed air with its lower part guided through exhaust channels (14,142). This directs the major part of the compressed air upwards to lead it away between the casing (2) and the drill stem together with the cuttings. A minor part of the compressed air is directed towards the drill bit (13) which is then sucked upwards along the side walls of the drill bit by jet action from the major part. Compressed airflow in the channels is controlled to regulate the minor flow intensity. The major part is directed through the exhaust channels which have adjustable passage area and are exchangeable.
