Drilling holes in the casing of the construction site s electrical distribution box
Casing drilling systems employ a specialized casing drill bit which is located in front of a DTH hammer, which drills into the ground while simultaneously placing a casing in the hole. In the electric welding processes, flat sheet stock is cut and formed, and the two edges are welded together, without the addition of extraneous metal, to form the desired tube. This is not a drill in the common sense, because it is not. 'Down hole' Casing advance drilling systems (CAS) are a critical part of modern drilling operations, revolutionizing how construction foundations, water wells and Geothermal energy wells are drilled.
