Concrete drilling is a handy and useful technique. This helps you put up shelves, install lights, put up hand paintings safely and quickly. The process is actually simple, especially if you have all the right tools and if you know exactly how to work on it. Below is a step-by-step guide you can follow:

Step 1

First off, identify where to perform the drilling. Mark the point using a soft pencil with either a cross or a dot.

Step 2

Put your drill exactly where you put the mark, and then drill briefly. If your equipment has speed control, use the lowest level of speed. Start with shallow holes, about ¼ or 3 to 6 mm, to guide your drill going to the real hole.

Tip: If the job needs a large diameter bit, start with a smaller bit for your pilot hole. This will maximise the stability of the drill.

Step 3

Continue your drilling with higher power this time. Place it on the hammer function, in case your drill has one. Set your drill on your pilot hole, making sure that it is exactly vertical to the surface of the concrete.

Drill with dense, but do not be too forceful; put pressure whilst pushing the drill forward. Slowly increase the speed of the grill and force if needed, but you need to make sure that your drill is under your control and stable at all times. If the drill accidentally hits a pebble or air pocket, your bit may skate easily.

Tip: Practice to ensure that you get the right amount of pressure.

Step 4

Pull the drill back slightly and push it back again with 10- or 20-second intervals. This can help pulling dust out of the hole.

Tip: Especially if you are using ordinary rotary drills, stopping and pulling it out can keep it from overheating.

Step 5

Remove all dust. This can improve the concrete anchor’s strength. Use a can or squeeze bulb of compressed air to successfully remove dust out of the hole. Then, using a vacuum, suck it up. Using goggles is advised to protect your eyes from debris and dust.

Concrete drilling is easy for small tasks. But if you need to do it for large construction projects, you better call Group 1 core & saw and leave the tasks to them. They have the right training and equipment to perform the task.
