1 Pilot Drilling
DRILLING SYSTEMS FOR HARD GROUND It is the working system which requires big efforts for the drill top, as it gives more power to the drill rods end. This power is transmitted through the drilling fluid, which gives rotating power to the head, by starting a hydraulic motor. The Drill Head - bit - is special for each rock type, drilling the ground progressively, and avoiding the hammering. |
