2132426 9321418 PCTABS00027 Use of a pressurized medium in a drilling apparatus for drilling a hole in the ground. The drilling apparatus comprises a drilling device (1), such as a down-the-hole drill or the like, the first end thereof having a drilling means, such as a drill bit (2), and the second end thereof being at least connectable by joining means (3) with one or more separate drill rods (4) for increasing the drilling depth of the drilling device in the direction of the longitudinal axis (k); scavenging means (8) for removing drilling waste generated by the effect of the drilling means (2); and a support frame (9) at least indirectly supported by the ground. The drilling device (1) is arranged to be driven by a feeding movement in the direction of its longitudinal axis (k) and by a to-and-fro or corresponding percussion movement as well as by a rotational movement or the like in relation to its longitudinal axis (k). The percussion means (6) of the drilling apparatus for providing the percussion movement of the drilling device (1) are arranged to be hydraulically operated by an organic, oil-based pressurized medium (m) derived from a natural biological metabolism, such as a vegetable oil, an animal oil, or the like.
