Drilling a bore hole is often combined with sampling and describing a profile. If both these activities are not necessary during the drilling procedure then drilling can be executed fast and efficient applying the so-called lost cone drilling method. Eijkelkamp Agrisearch Equipment developed a manually controlled set using an electrical percussion hammer to hammer the lost cone and the accompanying casing into the soil.

Applications
The lost cone drilling method is successfully applied when placing monitoring well pipes with a small diameter, for environmental research. After drilling the lost-cone is left in the soil. This does not cause any environmental problems as the material used is present in the soil by nature.
