Core Drilling Explained

Core Drilling Explained

Concrete drilling is the process of cutting a cylindrical hole in concrete, granite and a variety of other hard materials with the help of a special drill. It is widely used in the construction industry, geotechnical engineering and various other industries. While the primary use of core drilling is to cut a hole, sometimes it is also used to extract the material to be studied.

While there are separable applications of concrete coring, here’s a list of some of the most common applications:

  • Utility holes
  • Reinforcements
  • Plumbing pipes
  • HVAC ducts
  • Sprinkler systems
  • Electrical conduits

Sometimes, it may also be needed if a new window or door has to be cut out of an existing concrete wall.

How Does Concrete Core Drilling Work?

For proper concrete core drilling, a specific drill bit is required along with some accessories. The cutting edge of the drill bit is made of industrial diamonds just like blades used for other types of concrete cutting.

The drill used in the process is extremely powerful and heavy and there are a number of different types of drills used for the process. 

If the diameter of the hole to be cut is less than 3 inches, a hand-held drill is generally preferred but if the hole diameter is bigger than 3 inches, a drill with a standard attachment is used to keep the equipment in place.

Wet Vs Dry Core Drilling

Just like other types of concrete cutting, it could also be performed in wet or dry conditions. Wet core drilling is typically more efficient as the core tends to move faster compared to dry cutting. Wet core drilling also typically leaves a more finished surface as the dust generation is kept to a minimum during the process.

Wet core drilling is preferred for cutting a hole through reinforced concrete, soft or hard brick as well as concrete. In most cases, it is used for cutting into floors, walls or ceilings as well as for plumbing work or for the installation of electrical conduits.

The dry core drilling process is similar to wet drilling with the only difference being the absence of water for lubrication. Dry core drilling is used in cases where water can’t be used. For instance, if there are electrical wires nearby, you obviously can’t use water.

Benefits of Core Drilling

Core drilling offers a number of advantages compared to other cutting methods. Some of these advantages include:

1). It produces much less vibration and noise compared to other types of drilling methods such as using a hammer drill which makes it ideal for use in places where noise can be a problem such as schools, offices or hospitals.

2). It does not make too much mess which is not the case with other methods of drilling.

3). It is a much safer process of cutting through concrete compared to other methods.

4). It is a much more efficient process when it comes to concrete cutting as it is more accurate and more effective.

5).. It also costs less compared to other methods of concrete cutting.
