Whenever there is the need to drill a hole, we sadly look on a concrete or brick wall and think about how it would be nice if she were made of wood. However, wooden wall drill hole – a task not always easy. What would the wall in front of you was not to do in her hole, you need to know some basic rules.

Instruction

1. Holes, in General, is also need different. To hang on the wall of concrete or brick shelf, or watch, in most cases this will be a hammer drill with a concrete drill bit of the desired diameter. Alternatively, you can use a drill and the appropriate drill, but not every house you can find such a tool. Similar hole drilling easier, and this little one is having problems.
2. But for the laying of utilities (pipes, cables, etc.) through the wall may need holes of sufficiently large diameter. If the wall is of brick or concrete, without a good punch to them. And still need a special drill for drilling of concrete slabs and the understanding that if you need a hole with a diameter greater than 20 mm, one drill is not enough.
