Concrete core drilling is the process of drilling accurate, circular holes in a concrete surface. It is an excellent way to create openings for HVAC, plumbing, electrical systems, etc.

 

Contractors that offer core drilling services can drill holes of various sizes in diameter. No matter the area, they have the skilled operators to drill inside and outside.

 

Homeowners can take on some concrete core drilling projects providing they have the necessary tools for the job. If you are confident that you can perform core drilling, you will need to consider some key aspects to ensure that the job is done right without any issues. Following are the key aspects of core drilling:

 

Speed

Different types of drill bits have different ratings of speed at which you can use them. Don’t try to use more speed than recommended for the specific drill bits you are using. A higher than recommended speed can cause the drill bits to wear out quickly. It can also generate more heat within the concrete hence creating the risk of a fracture. So, be sure to operate at the drill speed recommended for the drill bits you are using.

 

Ventilation

The drilling machine has vents that allow air to cool the motor while you are drilling. Unfortunately, some inexperienced homeowners may cover these vents with their hands during work. This simple mistake can result in the motor overheating and lead to the armature (rotating coil) in the motor burning out, stalling the equipment. Ventilation is also required to get rid of any particulates or dust generated as you work. To ensure proper ventilation, it is recommended that you keep the doors and windows open. Run a fan if it’s available.

 

Pressure

A certain amount of pressure is required to keep the drill bit working optimally. Be sure to not exert too much pressure on the drill. Adjust it depending on the size of the drill bit. For instance, if the drill bit is tiny, reduce the pressure and apply more pressure if it’s relatively large.

 

Lubrication

Lubrication is a crucial aspect of successful concrete coring. However, some homeowners use inadequate lubrication so that there is less mess to deal with later once the concrete coring project is complete. This is not recommended. Skimping on lubrication can create more significant problems than a dirty floor. For instance, the drill bits will keep failing. Not to mention there is also the risk of concrete being fractured. So, try to minimize the impact of the mess. You can use plastic sheeting to capture all the slurry. It is also recommended that you use the proper lubricant. Water is a good choice as it cools the drill bit properly instead of oil-based lubricants that usually get destroyed by heat.

 

Getting all these key aspects right may involve trial and error, particularly if you lack the experience. To avoid the risk of all the mistakes as well as ensure that the project is completed promptly, it is recommended that you hire a professional core drilling Sydney company.
