Description
Drilling tool used in soils where there are rock stratifications.
The material used for the cylinder is characterized by a particular metal alloy with the ability to resist abrasion on the cone. At the base we place a crown of greater thickness than the cylinder to house the supports of the spikes.
The thickness of the cylinder, the size of the peaks and their inclination are factors that vary according to the power of the drill and the consistency of the soil.
