We drill holes in concrete: drilling methods using a
In this article we will talk about how to drill holes in concrete with the use of popular technologies and appropriate equipment. Taking into account the fact that concrete is one of the most popular building materials, most of the buildings, regardless of the purpose, are built using it.
Of course, during the finishing works and the subsequent operation of the building, additional processing of concrete is required, for example, for laying utilities for the withdrawal of ventilation ducts, etc.
An effective solution in this case is the device holes in the concrete. Consider the methods of drilling, which you can do yourself or order in specialized organizations.
Popular concrete processing methods
Cement-containing mixtures are not used as a building material for the first century. Again, reinforcing cement mortar with reinforcing bars to give it greater strength thought up more than a century ago. Of course, all this time the builders were concerned about how to make a hole in concrete, because the material in the final degree of readiness has high strength properties.
If the holes in the walls were literally punched, then today there are more accessible and effective solutions that anyone can use.
Apply impact drill
If not so long ago, the answer to a question than to make a hole in concrete was one - a dowel, then today the situation has changed radically, because now you can use a perforator.
The perforator is a type of drill in which the mode of simultaneous drilling of holes and slotting of the surface is provided. Impact drills vary in power, performance, type of drill and type of exciting mechanism - "cartridge".
Drills for such a tool are made of highly durable metals and, for the greatest efficiency, can be produced with a hard-faced surfacing, which has greater strength compared to the main part of the drill.
Drilling technology punch
- Before making a hole in the concrete, we prepare a drill of the required diameter. (diameter is indicated closer to the part that is inserted into the “cartridge”). As a rule, on the market you can find drills with a diameter of from 6 to 25 mm. Of course, there are products with a large diameter, but their use provides for the need to use powerful drills.
Cartridges for such drills have a larger inlet diameter with something that is used in household and semi-professional modifications.
- After the drill is selected, dip its reverse end in a special lubricant.if there is none, you can use ordinary grease.
- Then insert the bur with the lubricated end into the “cartridge” until click. If you feel a click, then the drill is securely fixed and the tool is ready for use.
- Drilling the holes with a hammer drill is easy. Do not put all the weight on the tool, as in this case, the impact efficiency will be an order of magnitude lower.
- Do not forget to periodically pull the drill out of the hole and free it from dust. If you do not do it in time, the likelihood that the drill will get stuck and the tool will jam and turn it out of hand will increase.
Important: When working with a punch, you must use personal safety equipment, namely, a respirator, glasses and special headphones.
If you need a larger diameter
If the question is how to make a hole in a concrete wall for sockets, switches, etc., the diameter of a conventional drill may not be enough. In this case, a slightly different approach will be required.
Consider how large holes are made.
Budget method
If there is a perforator and a small-diameter drill, and you need a hole under the "glass" of the socket in the concrete wall for installation, do not despair, as you will surely cope with the task.
We do everything as follows:
- We draw on the concrete contour holes.
- Then we insert the existing drill of small diameter into the perforator and drill a recess along the perimeter of the drawn contour.
- Next, remove the drill from the punch and insert the chisel, which comes bundled with most professional impact drills.
Important: We are not forgetting to switch the tool to the mode of cutting concrete (a hammer is drawn).
- Use the chisel to gradually select concrete from the circle marked by pre-made indentations.
As you can see, the technology is simple, but it has several disadvantages, among which are:
- impact on the surface of concrete, which adversely affects its overall integrity;
- the complexity of the work, as it is tedious to chop concrete with a punch;
- abundance of dust and noise.
We work without noise and dust
If you are interested in minimal noise and virtually no dust, diamond drilling of holes in concrete is exactly what you need.
However, choosing this method, you should remember that you will not be able to do the planned work yourself, as you have to use the services of professional specialists. Accordingly, the price of this service will be high.
Drilling and cutting of reinforced concrete with diamond circles and special crowns is a high-tech process, the result of which is the most even and accurate cutting surface.
Optimum quality of surface treatment is guaranteed both when drilling concrete, and when processing reinforced concrete. This results from the fact that the working tool is made of especially strong alloys which with identical success cut not only concrete, but also metal fittings.
The diameter of the finished holes can be from 42 to 500 mm. Drilling with the use of appropriate equipment can be performed both in the horizontal and in the vertical plane.
Important: Diamond cutting of holes in concrete is characterized by high speed of execution, which will significantly accelerate the commissioning of the object.
Conclusion
Now that you are familiar with the instructions for drilling concrete using available methods, you can apply this knowledge in practice. Remember that due to accuracy when working with percussion and cutting tools, the subsequent installation of technological holes in concrete will be an order of magnitude easier.
