Abstract (en)
[origin: EP1519000A1] An earth drill has a helical thread and shank that widens (32) to a larger diameter section (30) that terminates in a detachable cutting tip (46). After drilling to the required depth, the shank is detached from the cutting tip and withdrawn, thereby displacing the loose soil.
