Concrete core drilling is a method used for drilling any circular openings for electrical, structural, or plumbing installations.
What is Concrete Core Drilling?
Concrete Core Drilling is a process wherein a cylindrical part of a concrete structure is removed and separated from the rest of the structure. This means that instead of removing the entire structure being drilled only the perimeter of the hole is removed.
Though it may sound an easy process, it is rather a complex activity. This core drilling has multiple applications across various fields such as in floor drains, sewer drains, HVAC openings, handrail, and anchor holes, openings for cables, fibre optics, and phone and in structural testing. A range of sizes of the openings can be drilled up to any depth as per the requirement.
Learning About Concrete Coring as a Drilling Procedure:
Concrete core drilling is the creation of circular holes in walls and slabs.
Concrete Coring makes use of a diamond cutting drill, which facilitates the drilling of an absolute round hole in any concrete structure.
When talking about cutting, concrete coring is the preferred option since the process is noiseless, dust-free, and clean.
It is also important to choose a correct rig- electrical or hydraulic. When the drilling is to be on lightweight sensitive parts, then electrical rigs are used in contrast to the hydraulic rigs, which are used in confined spaces.
How is Concrete Core Drilling Done?
Concrete Core Drilling is done to achieve perfect circular cuts in asphalt, precast concrete, brick, reinforced concrete, and other structural materials.
This drilling can be done at any angle – vertical, or horizontal, or inverted, depending upon the requirement.
The concrete drilling equipment is provided with a diamond-cutting end attached to a steel tube. For stabilising the rig, it is affixed with the floor or a surface with the use of vacuum seal, bolt, or anchor.
For lessening the heat and reducing the resultant friction produced by the rig while cutting, the cutter is cooled down by water.
When the slug or the debris is removed, the cutting procedure completes, which gives precise round hole and that has caused no cosmetic damage during the process also that does not require any special aftercare whatsoever.
Prior analysis of the area to be drilled /cut is also crucial for identifying and spotting out any rods or conduits that might come in the way of the drilling process.
Points to Consider for Efficient Drilling
Following are the tips to take into consideration while drilling the cores:
Choice of the drill - For drilling cores up to 3 inches in diameter, a hand-held drill will suffice the need. Perhaps, for drilling holes of about 3.7 inches in diameter or greater, a rig-mounted or a drill stand unit is a requisite.
Choice of stand attachment - Utilize a vacuum stand for drilling openings slabs with considerably flat surfaces. For drilling in walls, anchors are used to attach the stand for a firm grip.
Power - For core drilling, there are three power options available, which are air, electrical, and hydraulic. Choosing one of the three depends on the onsite environment and power availability.
The depth of the hole to be drilled - Generally, the depth of 1- foot bit can be drilled using standard core testing samples. In case of drilling holes with greater depth, extensions, such as the barrel bits, are attached for facilitating efficient drilling and cutting.
Concrete core drilling is a difficult and critical task. Hence, it requires the expertise of the professionals for carving out the perfectly circular hole for various applications.
