REVERSE CIRCULATION DRILLING MACHINE A drilling rig is a machine that creates holes in the earth's surface. There are many different types of drilling rigs, but the most common is the reverse circulation drilling machine. This type of machine uses a rotating drill bit to create a hole in the earth's surface. The drill bit is attached to a long pipe, which is used to pump the drilling fluid into the hole. The drilling fluid helps to cool the drill bit and carries the cuttings back to the surface.
