The principle of this type of drilling involves the use of hollow drill bits through which a drilling fluid, consisting of refined clays in a mixture of water, is circulated. It is called a hollow drill rig because hollow drill bits are used and drilling fluid is circulated through them.

What is the role of a water well driller?
