Concrete core drilling involves the skill of drilling neat round holes in any concrete surface including floors and walls. It is the most recognized form of drilling. Concrete core drills come in handy when you require a shelf, want to install lights, or hang a frame.

Electricians and plumbers are the most known concrete core drill users because their everyday work duties require them to drill into walls, ceilings, and floors.


Concrete core drills can either use hydraulics or electricity.

They range in a diameter of 1/2 inch to 72 inches.

Their drilling capability is not limited to any depth because extensions enable the drill to go as deep as desired.

They offer a variable speed hammering function, depth setting, and good grip (the handle provides this and makes your work easier).

Plus, they are powerful.

Concrete Core Drilling Tips

If you would like your own quick fix toolbox complete with a concrete core drill, you can find one at your local store at a pocket-friendly price. Extra caution should, however, be taken when handling it. Here are a few tips to help you out.

1. Invest in a Quality Drill Machine

Keeping in mind the most useful features to look out for, do not be afraid to dig deeper into your pockets if you need a good drill for quality holes.

2. Familiarize Yourself with the Tool

Take time to go through the handbook that comes with the concrete core drill and understand it. It is advisable to be completely comfortable and knowledgeable with every part of the tool.

3. Set Required Depth

Measure the desired length and mark it using a pencil. Some drills, however, have depth control features on them, which make the depth setting process simpler.

4. Holding a Drill

A drill is held with the index finger holding the trigger. Place the other hand on the handle or at the back of the drill if the handle is not present.

5. Identify the Drilling Point

Use a pencil to mark the point where you want to drill, and then place the drill point on the mark made. Do not put any kind of pressure, just place the tip on the point.

6. Drill

Start drilling using low speed at first at the marked point. Increase speed and pressure while drilling and occasionally pull the drill away. Drill until you reach the intended depth.

7. Safety Precaution Measures

In any handy job where you are required to work with tools, you must always ensure safety measures are carried out. It is highly recommended to wear goggles to protect your eyes from particles that may blast from the surface being drilled. Additionally, always wear a dust mask to avoid inhaling dust particles.

Also, if by any chance you use water or you are drilling a wet area, ensure the drill does not get wet, otherwise you could get electrocuted, especially during a plumbing job. As a precaution, beware of concrete particles that may fall from the drilling. To safeguard your hands, wear gloves to prevent injuries from hot bits or sharp objects. Also, wear ear muffs to protect the ears against noise from the drill.
