Concrete is a popular choice of construction material due to its remarkable structural strength and durability. On the downside, however, it is difficult to break or cut through concrete when need arises. With the right technique, specialised equipment and skilled personnel, however, it is possible to drill into concrete with relative ease. There are plenty of methods that can be used to get the job done. One of the most commonly used methods today is concrete core drilling, which involves using a specialised power tool (known as a core drill) to create holes into concrete material.
So, what makes core drilling one of the most sought after ways for drilling holes in concrete structures?
Minimal surface deterioration
Core drills have high material tolerances for concrete. The drills are designed to cut out the perimeter of the hole and not the entire cylinder of the concrete material being drilled. Because a smaller amount of material is removed, the debris or rubble that would have to be cleared off from the work site is considerably reduced. The amount of time and labour required to do patchwork once all holes have been drilled is also reduced.
Core drilling concrete holes is a vibration-free process; unlike when using conventional tools like rotary hammers or hammer drills, there is no hammering action applied to the surface as the holes are being created.
Limitless range of concrete hole sizes
With an extensive array of specialised coring drills available out there on the market these days, your contractor can drill smooth, perfectly round concrete holes of any size to meet the exact requirements of your application. The core holes can even be bevelled or multifaceted according to specifications of your electrical, plumbing or any other project.
Suitable for use in space-restricted areas
Another advantage of core drilling concrete holes is that it can be used to work in very tight spaces because core drills can set to work in any orientation, be it vertical or horizontal. When working in tight spaces, the contractor will drill core holes in an overlapping sequence around the perimeter of the surface where the material is to be removed.
Variety of power options
Core drills can be powered in so many different ways. Even though most drills are electric-powered, you can also find pneumatic, hydraulic or air-powered versions for use in a variety of special environments, e.g., pneumatic versions can be operated underwater.Share
