The turning bit often gets hot, so water or mud is used to keep the drilling bits cool. Rock is carried to the surface as the bit turns. The most common types are long cable bits or interlocking steel bits – both which rotate in a clockwise direction to bore into the earth and loosen the soil. A rotary drill rig uses an assortment of bits. Drilling rigs are either rotary drillers, which bore down into the earth using a circular motion or a “pounder,” which raises and lower a heavy weight in a technique known as 'cable drilling' to punch holes. Watching a well-drilling rig in action can be pretty impressive here’s how it works.Ī well drilling rig is a large piece of equipment that must be brought to a site by truck and put into place on the site where the well is to be dug. Although many homeowners in New Hampshire and Massachusetts draw their water from a private well, chances are they didn’t have to hire a well contractor themselves and were not there when the well was drilled.
In the nearly 40 years Skillings & Sons has been in the well drilling business, we’ve found that people often don’t think about the work and technology that goes into having a reliable source of clean, great-tasting drinking water.
