The hydraulic, bi-directional auger allows a precise and quick work. Its strength offers high performances. The 3 pin options allow to use the auger in soils of different consistencies. The Standard bit is suited to low-medium consistency soils. The Medium bit drills the mixed grounds of medium-high consistency. The Rock bit works in the most difficult and hard ground conditions, where rocks are encountered in a high percentage. With a standard length of 1000 mm, the extension boom increases the drilling depth. It is also possible to realize extensions of different sizes following different drilling depth needs.
