Concrete drilling: equipment selection. crown job

Building

Concrete is one of the most durable building materials of modernity, which is used in almost all stages of the construction of buildings. At the same time, it is very often combined with metal fittings, creating structures that are simply unique in their characteristics. Therefore, drilling of concrete with a crown is carried out according to certain rules and using a special tool.

Features of the work

To begin with, it must be said that all the equipment necessary for this work is quite expensive. This price is due to the fact that all units used for this purpose, have great power. Also, the surface of the tools is usually created from carbide elements that have a high production cost.

The use of special drilling stations, which greatly facilitate this process

Equipment selection

In order to easily drill holes in concrete, you should purchase or rent professional equipment in the form of a perforator.

It must have great power and have the ability to translate torque into translational motion.

  • Standard crowns for drilling concrete use pointy tips, which are very quickly erased, but have the ability to sharpen. At the same time, their cost is relatively small and, therefore, they are available even to novice masters or for the production of one-time works.
  • There is also diamond drilling of holes in concrete, which uses the hardest mineral as a cutting surface.. Such attachments are very expensive, but the quality and ease of working with them deserve such expenses.
When drilling, it is necessary to supply coolant, which not only maintains the condition of the tool in proper form, but also softens the surface
  • Special attention should be paid to the machine for drilling holes in concrete. This device can make not only circular cuts, but also use various configurations for this. Also, the installation for drilling holes in concrete has tremendous accuracy and is easy to operate.
  • With the development of modern technologies in construction, more and more special equipment appears that can facilitate the most complex tasks.. A striking example of this innovation was laser drilling, which is increasingly beginning to gain popularity.

Tip! It is necessary to acquire or rent the equipment that is most suitable for specific tasks and at the same time spends the minimum amount of resources. Otherwise, the creation of the simplest hole in the concrete wall for the installation of the socket may cost, as the decoration of the whole room.

With the passage of the wall, the crown should be immersed in the material, which means that there should be no obstacles on its way even behind the working surface.

Crown job

Typical drilling of reinforced concrete begins with the fact that with the help of a special device, the location of all the metal elements in the object is found.

This is necessary to avoid cutting parts falling on the reinforcement, which will certainly lead to the failure of the tool.

  • It is worth saying that there is equipment for drilling holes in concrete, which is not afraid of such consequences. However, it is usually expensive or requires some kind of consumables.
  • Further drilling in concrete with the use of a crown needs to determine the center of the future hole in which the drill bit is installed. In this case, it is necessary to adjust it in advance so that the center tip of the center extends beyond the edge of the rim by only 1-2 centimeters.
Since such stations are firmly fixed on the surface, they do not change their angle of inclination during operation, which is also a guarantee for obtaining a regular shape hole.
  • In modern construction, drilling and cutting of reinforced concrete with diamond circles is quite often performed at one stage of installation. Therefore, masters can see the location of the fittings and cables with electricity, and avoid meeting with them.
  • When the cutting surface is in contact with the concrete, strong friction occurs as a result of friction. A conventional concrete drilling machine is equipped with an automatic supply of a cooling emulsion, and when using hand tools, this will have to be done independently.

Tip! Professional craftsmen regulate the speed of rotation of the nozzle on their own. For novice builders, it is recommended to use the average parameters of the equipment, making adjustments in the course of work.

If it is necessary to obtain openings of large diameters, the entire perimeter of the circle is drilled with smaller tools, but the quality and evenness of the edge in this process cannot be guaranteed

Drilling features

If this work is done for the first time and with your own hands, then you should first consult with experts who will tell you what equipment is better to pick up and what else may be needed.

The unit for creating large openings is used quite rarely, since it is much easier to foresee the creation of such elements during pouring than to use expensive equipment
  • If you do not cool the nozzle in the process, it will become dull very quickly or cutting elements may fly off of it, since the material fixing them under high temperature will lose its properties.
  • Usually a special instruction is attached to such equipment. If it is not, then you should immediately consult with the seller, especially when choosing accessories.
  • When working with a perforator, it is necessary to constantly maintain the angle of inclination of the device to the surface. If you do not do this, instead of a round hole you can get an ellipse or a torn entrance. (See also the article Cutting concrete with a grinder: how to do it.)
If necessary, you can purchase a special fastener that allows you to turn a conventional punch into a similar station

Conclusion

After reading the video in this article, you can study in detail the methods of drilling holes and learn about the necessary equipment for this. Also, on the basis of the article proposed above, it should be concluded that this process is rather expensive and requires not only tools, but also the corresponding consumables.
