Drilling a hole is much easier with a hammer drill or a rotary hammer for large jobs. Both hammer drill and rotary hammer fracture the concrete through a rapid hammering; the drill scoops out the broken materials. One can buy or rent a good hammering drill so as to drill the concrete in an easier way with the help of these tools.
During drilling the concrete task, one should own safety goggles, gloves and ear protectors. Goggles shall protect the users eyes from chips of concrete, ear protectors will protect the ear drums of the user from any physical damage that may leave the user dumb or deaf and the gloves will protect the user from any abrasion and any heat produced by the drill. When you are about to drill the concrete make sure that the masonry drill bit is well inserted and the depth of the drill is set so as to enable a safer environment for drilling the concrete. Hold the drill in a proper way with one hand like a gun while the index finger on the trigger. If the hammer drills it has got one more hand to hold use that hand to hold the hammer drill.
Here’s a list of tools that you should have before setting on for work:
- A pencil and a ruler
- A hammer Drill
- Carbide masonry bits (Tungsten)
- Can of compressed air
- Masonry nails (3” long)
Here are a number of steps can should be taken into consideration when you drill into a concrete
Step Number 1: Mark the drilling spot on the concrete where you want to drill, this spot can be made by the use of a soft pencil. Drill a polite hole by placing the drill on the mark and drill briefly using a low speed power, continue drilling with more power of which it can be made possible when the hammer drill is set at a high speed power. You can wrap (all around the drill bit) a small bit of masking tape so as to make it visible where you should stop
NOTE: Apply enough pressure to hold the drill in place but do not force the drill forward.
Step Number 2: Forcing the drill forward it may increase the rate of wearing out of the bit hence one is usually advised to do the forward and backward pull and push force of the drill in order to make the work easier. Break through the obstruction with a masonry nail and at the end blow out the drill by dust by the use of a can compressed air.
Step Number 3: You will be in a need to make a rough guide hole at first. It will make it easy for you to drill. And you must know that the all types of hammer drills offer two speeds only. So, it will be best to control your drill while creating the guide hole if you turn the drill at a lower speed. The guide hole that you will create has to be 1/4 inches deep or you can make it to 1/8 too.
Step Number 4: Only when you feel a bit confident about your drilling style, you can turn the speed faster but don’t forget to maintain a firm grip using both hands on your tool. You got to drill into concrete until you get the hole completely done.
Step Number 5: Be careful when hitting the obstructions because you might damage the drill or bits if you force your drill (beyond limit) into the concrete. You might end up losing control over your drill resulting into a messed up hole or worse can happen, you might end up damaging the concrete surface itself.
As soon as you find yourself in a position where you see your progress slowing down because of the tough-to-crack area, you can put down the drill and go on for the masonry nail and a hammer. Place the masonry nail’s tip at the problematic area and tap it with hammer (not so hard). Now, easily you can break down the obstruction. Once you are done with these areas, get back to the drill and put the drill on a lower speed until you get passed through the rough patches.
Step Number 6: After a few intervals, you have to keep the drill on a rest and brush away the concrete dust. You should pause for like 15 -20 seconds if supposedly you are drilling a two inch hole and using the drill for a minute or so.
Step Number 7: After you are done with drilling your hole to the required depth, you should blow off the concrete dust with the help of compressed air and then clean up the area.
NOTE: You must keep on doing the drilling task with your goggles on just to protect your sensitive eyes against the concrete dust and remains that can fly up to your face and hit you or scratch the eyes.
