Starting repairs in the apartment, many are faced with the fact that you have to drill holes in the walls. This work is one of the most difficult among other repairs. After it, it is necessary to eliminate building dust and debris for a long time. Drilling holes in the wall must be carried out in accordance with safety regulations. It is easy for a beginner to get injured in the process. You can cause serious damage to neighbors by accidentally hitting communications.
What does drilling safety mean?
Drilling holes in a concrete wall must occur subject to certain rules:
- Before starting work, you need to take care of your own protection, purchase a respirator, as well as glasses. It must be remembered that with this process it is easy to spoil clothes or injure themselves, therefore, the use of special protective ammunition is recommended.
- It is necessary to take people away from the territory where the repair will take place. Do not forget that on the other side of the wall there can also be residents. If you are going to drill an external wall, then you need to leave a person on the street who will warn passersby about the start of work.
- It is unacceptable to work with a hammer drill at a height. These types of work include a rise above 1.5 meters without special devices. Usually for this type of work they get a ladder. It is better not to use a stepladder, as there is a big risk of injury.
- Work with a power tool should begin smoothly, gradually increasing speed. When choosing a tool, it’s worth stopping at two-handed.
How to drill walls through plaster?
To get a neat hole, you must:
- View a plan of all communications, learn how they go. If in doubt about their location, it is best to consult with a gasman and an electrician.
- Before drilling, plaster must be removed. To do this, use a barb, as well as a bench hammer.
- Do not start drilling walls on decorative surfaces. It is difficult to detect wiring under them, usually even a special tool does not detect it.
- If the house is built of blocks, you can not make holes through the seams. Usually gas pipes or electric wires are hidden there.
- Some houses hide gas wiring. In this case, the gas supply is turned off during the repair.
What should be the tool?
Drilling holes in the wall can be carried out with various tools. It all depends on the thickness of the wall and what it consists of.
Drilling holes in a brick wall is easier than in concrete. To do this, you need a two-handed drill. It should be shock-rotational. The power of this tool is better to choose from 350 watts. Better to choose with a self-locking chuck.
When 2-2.5 cm of the wall is passed, you can drill holes with a three-jaw chuck.
Drilling holes in a concrete wall is best done with a tool that has a collet chuck. You can make several holes, and then switch to a drill that has an SDS plus cartridge. This tool has a shank diameter of 10 millimeters. It is better to choose a two-handed drill. It must be shock.
If you have long work with concrete M400 and with monoliths, then it is better to choose a drill SDS max. The diameter of the shank will be 18 millimeters. The most commonly used universal punch for any design and material. He copes with drilling, and also chisels.
Often used diamond drilling holes in the wall. It is carried out using a drill.
In order to drill a hole in the wall, diamond drilling is most suitable. Small holes are neat, but this takes practice.
In the case when you need to drill a large hole, the diameter of which will be up to 250 millimeters, an excellent option is the use of a motor drill. It must be powerful, not less than 8 kW. There is a nuance in the work - you can not include it in a single-phase network, which most often stands at home.
How to drill concrete?
Getting to work, the tip is pressed to the center of the future hole, choose a hole. To do this, the cartridge rotates manually. Turn on the instrument, slightly moving it to the side. Drilling begins with an increase in speed, as well as feed.
Professionals most often use a carbide crown. It is pressed against the wall, the tool is launched sharply, although this is unacceptable by technology. It turns out an additional gap, where moisture can then accumulate.
The drilling technique may vary for each individual case. When working, it is important to have a special small metal detector that will help determine where the fittings go. It can be bought at a hardware store. It is inexpensive and runs on batteries. The key to success is a properly selected tool and safety precautions. If you understand the technique of work, then the work will be easier than it seems at first glance.
How to make ventilation holes?
Drilling holes in the wall for ventilation is most often carried out by a diamond shockless method. The main advantage of this method is that you can drill at an angle and through a brick, as well as process other materials. Such drilling holes in the wall is easy to learn on their own. It is important to follow the instructions above.
Diamond Drilling Benefits
Nowadays, it is the most progressive method. It has several advantages:
- Obtaining the ideal given hole shape.
- Does not make large scratches and chips. No need to re-pass the work surface with a tool.
- The working crown is very cooled in the process, due to this the channel is formed faster, the speed of work increases.
- The exact coordinates are set, the work occurs only in the originally specified area.
- The minimum noise level, practically there is no vibration from the tool.
- After work, there is no large layer of dust and debris.
- Large range of channels. The largest diameter is 0.5 meters.
- In the process, cracks on the walls will not appear. They are when working with percussion instruments.
One of the important advantages of this method is the drilling of recesses up to one meter deep. Due to uptime, time is greatly saved.
Disadvantages of diamond drilling
Drilling holes in the wall with the diamond method has several disadvantages:
- The diamond nozzle is cooled, the floor is contaminated with a special compound.
- The cost of working with such a tool usually increases.
- It is better to attract specialists to work on concrete, they are specially trained before work.
- The intensity of the work is affected by the forces that are applied to the tool.
- Crowns quickly fail. They need to be changed periodically, and this is an additional expense.
