Drilling machinery is equipment used to drill holes in the ground for such activities as prospecting, well sinking and scientific explorations. Drilling holes in rock to receive blasting charges is an operation in tunneling, mining, and other excavating.
Most modern drilling machines are either percussive or rotary. Percussive drilling machines chip away the rock or grind intermittently while rotary use a cutting or grinding action. A combined rotary-percussive drill uses both types of action when the hardness of the rock needs it.
The earth auger is the simplest rotary drill, which is hand-operated and looks very much like a wood auger used in carpentry. This auger is used primarily for drilling holes in the soft earth.
Rotary drilling is also used for underground mining. There are three kinds of rotary drill bits:
drag bits, which cut the rock with two, three, or four wings, sometimes tipped with tungsten carbide, and are used mostly in soft rock; roller bits, which operate with a crushing action by means of wedge-shaped teeth and are used for harder rock
and diamond bits, which grind away the rock.
Percussive drilling is much slower than rotary drilling and has other uses, such as for shallow holes. In percussive drilling, blows are applied successively to a tool attached to rods or a cable, and the tool is rotated so that a new portion of the face is attacked at each blow.
