The invention shall look on HingtieflochheMBtr, especially for performing core drilling in rock, old Rin a _t drill bit, a core tube and Onea Kernfsngrlnf ·

To carry out core drilling »ι · Β · for soil and Geoteinauntorauohungen, who it was so far usual and necessary, Diaiaant drill bits see below · Bas drilling had to be done with high * external pressure and old high rotation speed. For flushing you can « only Nasser has been used, so that for a sufficient amount of time Water supplies must be provided. Furthermore, who it is inevitable, the entire drill pipe sur recovery of core pieces each after relatively short drilling distances (about 1.5 b) out of the way.
