Concrete Surfaces: Simple Core Drilling Tips for a DIY Project

Concrete is an advantageous construction material for residential surfaces because of its high strength and resilience. On the other hand, this toughness makes the pertinent surfaces difficult to modify. In simple terms, you cannot make direct alterations to the hard concrete structure. Therefore, if you would like to install pipes, electrical conduits or data cables within a cured residential surface, you will need to drill the concrete material.

Basically, this process involves the use of a core drill to create a hole and remove the internal cylinder of the concrete. In ideal circumstances, you should have a professional contractor perform the task for efficiency and safety. However, if you have the machinery, time and some mechanical knowledge, you can carry out the project. Here are critical tips to help you perform concrete core drilling without expert assistance.

Use Water Efficiently

The core drills which are designed for concrete cutting have diamond bits, and the equipment is built to use water for cooling purposes and to prevent accelerated wear of the bits. However, this is not the only purpose of the water; this fluid will also determine the drilling efficiency of the bits. Basically, it will combine with the dust to form a slurry mixture which will lubricate the bit and improve your drilling efficiency.

If the water used on the surface during drilling is too little, there will not be enough lubrication. On the other hand, too much water will carry away all the concrete dust, so slurry will not be formed. Therefore, you must ensure that you have used the right quantity of water for your task. You will get the best results by pouring enough water on the concrete to form milky slurry.

Anchor Your Drill

You should always anchor your core drill before starting the drilling process. This is particularly important if you do not have extensive knowledge or past experience with the tool. When you anchor the drill, the holes created will be straighter. In addition, the tool will be more stable so you will be safer. If you are drilling a horizontal surface, you can use a vacuum base anchor. However, for walls and ceilings, choose specialty drill stands or ceiling jacks respectively.

Moderate the Drilling Speed

There are recommended optimal drilling speeds presented by core drill manufacturers for different materials. High speeds could damage the drill, and low speed compromises efficiency. Therefore, you should read the manual or make inquiries from your equipment rental store so that you will use the right speed settings.
