Sometimes you need to drill into concrete. Maybe you have an apartment with all concrete walls and want to hang a picture or a mirror. Maybe you need to drill a hole straight through the foundation of your house for your tv cable. Many people look at Drilling in Concrete with horror.
They find it difficult to believe that they have the ability to do tasks like that, and call professionals, paying them big bucks.
1. Use The Correct Cordless Drill And Bits For The Job:
Preferably you should have a good and powerful hammer drill with a 1/2 inch chuck. Drilling in concrete with a good Hammer Drill compared to a conventional drill is just like night and day.
In an ideal world, your drill should at least have a max torque of 600 inch-pounds, especially if you are going to drill in the thick foundation, but a 400 inch-pound drill will do the job as well. When drilling in concrete I prefer to have at least an 18v cordless drill with two Lithium-Ion Batteries and a rapid charger.
When you are going to drill holes in a concrete wall, preparations is extremely important. If you drill in the wrong place, you have to cover it again with cement. An easy task, but quite annoying.
Do the measurements on the wall correct and you don`t have to worry. You also have to have some kind of control over how deep you will drill. An easy way of doing this is to take the desired hole depth and mark the drill bit with a piece of colored tape.
3.Drilling of the concrete wall:
I assume you have marked your drill spot with a cross and are ready for drilling. Make sure you’ve put your drill in “hammer mode” and your dual speed option on high speed. Put the tip of the drill into your cross on the concrete. Take it out about 1 inch and start the drill by pushing the button slightly in.
Touch the cross and increase the speed a little bit. When you got a small “guide pit” you can increase the speed to full speed.
