Features of work with concrete and the choice of tools
Tools:
- Drill.
- Perforator.
- Chisel.
- Hammer.
- Drill (for metal and winning).
- Rosted or diamond crowns.
- Drilling installation (for diamond drilling).
At the moment, most buildings are built on the basis of strong concrete plates. And you, most likely, will have to sooner or later encounter the need to drill concrete walls. And given that often there are stones and steel reinforcement in the design, the task becomes really complicated. Even if you have a winning drill and a powerful drill. In order for the work to become easier and more understandable, you need to initially choose the right tools and study the step -by -step instructions according to which the holes in concrete will occur.
The increased strength and reliability of concrete structures implies the need to use specific tools and devices for work. The drilling method must be determined before the start of work, based on the desired diameter of the hole and the presence of reinforcement in the concrete plate. Without preliminary analysis of the material, it is impossible to drill a hole in concrete accurately and carefully.
Modern cutting nozzles used in the process of drilling allow you to make holes of almost any depth and diameter. They differ in their length and shape. Such nozzles allow you to break through a strong concrete plate without much physical effort. But to drill holes with a small diameter, it is quite possible to use a drill or drill. The cutting nozzles are equipped with a carbide tip, and their rod has a screw shape. Thanks to this, they can easily delve into a solid concrete surface.
If you use a shock drill, then you need to choose drills with a cylindrical tail. Their surface should be even and smooth for better sliding.
Useful information: during drilling, cutting tools are significantly blunt. From time to time they will have to be sharpened and then continue to work. And if you use winning drills, do not forget that they are susceptible to high temperature. Therefore, you need to take breaks and let the drill cool. At the same time, we also recommend lubricating the drill with a special liquid that reduces the heating rate.
In order to make a large hole, you will need a crown to drill concrete. It is a hollow cutting tool of a cylindrical shape. Its key feature is that all the cut material passes into the cylinder. Thanks to this, Kern does not prevent the normal entry of the tool into the plate. Some of the crowns are equipped with special cutting segments or high -strength diamond crowns.
If you use a perforator, it is best to use crowns with teeth of solid metal alloys. Diamond spraying is necessary when unstressed drilling with the use of coolant occurs. A great advantage of such a tool is wear resistance. However, during operation, it is still blunting and you will have to restore it. If you drill a small hole, for example, a hole under the outlet in concrete, the tool can be held in your hands. With more complex work during drilling, it is necessary to fix a special drilling rig to the wall using anchors.
Among the most frequently used tools are perforators and electrodelers. They are great for drilling holes up to 10 cm. However, the reinforcement in concrete can easily break a drill or teeth. Therefore, we do not advise using gear crowns for drilling reinforced concrete structures.
Always first study the characteristics and features of the drilling tool and material, then select the best option. If you do not have the opportunity to use a perforator, you can use a shock drill. But take into account that the effectiveness of such a tool is an order of magnitude worse. But with small volumes of work, it is quite enough for you.
Drilling of large diameter is especially complicated. Here you will have to use diamond drilling holes in concrete. It is quite difficult to produce it yourself. In addition, you will have to use an unstressed electrical appliance with the possibility of water supply to the concrete surface at the place of drilling.
How is the drilling process?
In order for all the work to be completed with maximum accuracy, follow the instructions below.
Determine which tool you will use for drilling. The shock drill is suitable for creating holes with low depth and diameter, and the punch due to its higher power and speed is suitable for more difficult work. But the principle of working with both tools is not much different.
There is a strict sequence by which concrete slabs are drilled:
- Study where the wiring lies in your walls. Perhaps for this you will have to contact an electrician. If it is not possible to designate the places where the wiring lies, in no case do not drill at random. This is fraught with serious consequences and is dangerous for health or even life.
- Mark in places where you will drill holes. Take care that you have a protective point and at least a gauze bandage to protect against dust. It is most reliable to use respirators.
- At the points of drilling earlier, make tags with a drill with standard sharpening. This will help you initially correctly direct the drill in the right direction, and it will not slip to the side at the first attempt to drill.
- The stones are best broken by a punch. Its cost is much lower than a cutting tool for working with concrete, and you can find it in most building sets. And if not, then you can buy it separately in the nearest store of building materials and tools.
- In the process of drilling every 5-10 minutes, you need to cool the drill with water. Overheating can cause deformation of the drill itself, and it is almost impossible to straighten it to a normal state. We'll have to throw away and take a new one. A deformed drill can cause significant destruction on the surface of the concrete structure.
- Most likely, sooner or later you will come across reinforcement or dense stones. You will hear a whistle and a characteristic ringing of reinforcement at once. The drill must be immediately removed, and instead use a punch and replaced by a whiten one with a regular one designed to work with metal.
- When you drill concrete, after every 1.5-2 cm, you need to turn back movements without turning off the drill so that the dust formed and garbage is spilled out of the hole. Thus, almost all of the baby is removed, and you will smoothly get to the reinforcement without damaging the tool. Make sure that in the process of drilling you do not deviate from the initially set angle. Keep the tool tightly and tightly stand on the floor without crossing.
- In order for the amount of dust flying around the room to be less, you can make a funnel on a drill or a punch from a conventional plastic film. This is an optional step, but he will protect you from problems with a large litter of the room.
Advice. If you need to make a hole, for example, under an outlet, you can make several small in diameter at once, and cut out unnecessary concrete with a hammer and a chisel. But take into account that the edges are likely to be uneven. The selection of the crown of the desired diameter will greatly simplify the work. A great option is to combine the work of the chisel and crowns. First, do a rough job, and then just correct the hole with a crown.
Drinking concrete with diamond crowns
This method has a number of advantages over the rest. Diamond drilling provides fast speed, accuracy, low noise and vibration. The technology is not in vain one of the most popular in construction work around the world.
The drilling process can occur in different planes and almost at any angle. It doesn’t matter if this is a vertical wall, a ceiling or just a concrete slab lying at an indefinite angle. With this method, the drilling depth sometimes reaches two meters and does not require much effort to work. The diameter that can be drilled reaches 50 centimeters. The speed with which drilling occurs in most cases is from one to six centimeters per minute, which is quite good.
For drilling, you will have to use special equipment diamond ring crowns. The drilling installation must be placed on a special bed and fixed with anchors or a vacuum plate. The process of transporting equipment and its installation itself is quite laborious, but the work is greatly simplified and is much more accurate. In addition, with the help of the guide, the angle is fully adjusted, under which the hole will be drilled.
When starting the installation, it is necessary to wait until it gains full speed. During this, water is supplied with pumps to the place where the future hole will be located. Water will cool the surface, equipment itself, as well as eliminate dust and dirt.
The main disadvantage of this method of drilling is the cost of equipment. There is usually no question of buying it. Yes, and rent can do very expensive. Especially if these are really new models with a wide range of functions and the possibilities of accurate configuration. But with the proper use of such a diamond installation, all costs quickly pay off due to the highest speed, accuracy and minimum noise, which will not irritate you and your neighbors. Therefore, we advise you to overpay if you need a really high -quality result and a minimum of problems. In addition to the foregoing, we will definitely emphasize that after working with such a tool there is no need to additionally process holes, and dust and garbage from it are many times less than when working with a conventional drill or perforator.
And if you are seriously configured to make holes in concrete yourself, the tool is the first and most importantly that you need to choose with all responsibility. And then follow the instructions and get a quality result.
