Many people find it easier and cheaper to do their basic around the house fittings by hand rather than hiring a professional to do them. There is nothing wrong with this approach, but some care does need to be taken when you are drilling holes into walls.
It is not as simple as getting drill bits for a wall and just making a hole in the plaster. You have to consider a number of different aspects.
The first is the location of the hole. If you can see where the bricks meet, it is a good idea to drill there. Drill bits for a wall handle the softer masonry much better than the much denser brick. You will stand less chance of blunting it or damaging your drill .
You also need to consider the depth of the hole. Do not drill to deep. Many walls contain electrical wiring and drilling may damage these if the bits for a wall go too deep and hit a wire.
Then you need to use the right type of drill bits for a wall. In order to decide what kind of bits for a wall you need, you need to know what kind of material you are going to be drilling into. A bit that can handle plaster may not be able to handle concrete or masonry, while a bit that is too thick or too rough may cause a lot of damage to the surrounding areas.
How much pressure should you put on the drill ? It is important to put enough pressure on the drill to keep the bits for a wall in place, but not to use all of your strength as that could break the bit or even the drill itself.
Use the right kind of drill . The best drill is a hammer drill . This is because a standard drill slices into fibrous material while a hammer drill uses a combination of two actions – hammering to break the aggregate material and scooping out the bits that break loose. This is why a standard drill works better for materials like wood while a hammer drill works better for man-made substances.
And the right kind of screws. The screws you use have to be strong enough to handle the weight that is going to be put on them or they will either break or pull loose from their moorings.
You also need to remember to protect yourself correctly. Dust and debris can easily get into your eyes and lungs, as such you need to wear safety goggles and a dust mask to protect yourself from this. It is also a very noisy operation and it is a good idea to wear ear plugs to protect your sensitive ear drums from the noise.
So, as you can see, using drill bits for a wall is not as easy as attaching the bit to any old drill you have lying around and running riot with it. You have to be careful about where you drill and how deep you go and you need to protect yourself from the inevitable debris and noise.
