Difference between Drilling and Boring

Construction is one of the biggest industries in the world and there is no point in time when someone somewhere is not indulging in this activity. Generally the idea is to construct structures and that are functional and aesthetically pleasing. However, there are times when there is a need to deconstruct or alter them for the greater good. Depending on the size of the project, it is sometimes better to just modify the current structure. It is certainly not uncommon and happens all the time.

This can be done by demolishing them altogether or simply making alterations for the purpose of making needed changes. Drilling and boring are two concepts that you often come across in this regard. The two are different from each other and are used for various purposes.

Drilling is a process in which a hole is created in a solid structure. Boring is the internal cutting of a structure where there is already a hole. The job is to make it bigger.

Drilling can be done on a number of scales from a simple tiny hole in the wall to much larger ones such as oil wells. Boring is done on a large scale only due to its inherent nature.

    The process of drilling involves machinery that will power the drilling equipment. It can vary in power and size depending on the purpose for which it is being used. To make the hole, a drill bit is used which is made from very tough materials. Its face is quite sharp to do the job.

    Drill bits can be made of metals in some cases. More advanced drilling requires better drills and in some cases, drill bits made of diamonds are often used.

    Drilling can be done for as little as fractions of an inch to miles into the earth, once again, depending on the purpose of the job.

    The general purpose of boring is to make a hole or well in the surface of the earth. It is also used in order to make tunnels. Boring is used in various fields including geology, oil and gas industry, civil engineering and hydrology among others.

    The deepest boring thus far on record was done by the former USSR which is 12000 meters. The purpose was to get samples of the core but the nature of the rocks in the lower layers of earth made it impossible to continue the journey.
