How to drill into concrete with a impact drill
There are several steps to follow when drilling into concrete. These are:
Marking the spot
You should start by marking the location where you are going to drill a hole. In addition, you need to think about how deep the hole should be. You can measure this with the help of a stop bar. You can also determine the depth by wrapping masking tape around the drill.
Prepare the drill
Wear your safety glasses. Next, you need to insert the right size concrete drill into your impact drill. Make sure it is properly locked to prevent slipping while drilling.
Put yourself in the right position
Hold the drill firmly and place your feet shoulder-width apart. To get more control, you can use the extra handle. If there is no extra handle, you should hold the hammer drill in the same way as a handgun. Care should be taken to keep the drill perpendicular to the concrete. The hammer action will cause some recoil.
Drill a guide hole
When the drill is on a slower setting, make the guide hole. If the drill has only one speed, you can use it in short bursts until the guide hole is about 1 cm deep.
Drill the desired hole
Hold the drill firmly but lightly. This will allow you to tackle any rock piles or hard material in the concrete. It is easy to lose control of the drill when drilling through concrete. With the guide hole in place, you can easily control the drill. As you become more and more confident, you can now increase the rotation speed until you have made the complete hole.
It is advisable to pull the drill back after every 10 seconds to remove the debris from the hole. This will allow the drill to continue working on the hard concrete without being bothered by the grit.
