Diamond drilling rig buy or not, what is the price?
Deciding on the question: “ Diamond installation Should I buy drilling or not? The answer is obvious - the machine diamond drilling holes in concrete makes holes itself different diameters and depths in concrete, reinforced concrete and other hardest materials; does not create strong vibration during operation, which significantly simplifies the work process, reduces the noise level, and does not damage or chip the material being processed; there is no dust cloud. Diamond drilling rigs They are absolutely safe for the environment and human health, therefore they can be successfully used in residential premises. If you want all the resulting holes to be completely smooth, clean and not need any additional processing, you definitely need to buy it! Price diamond drilling rigs may vary greatly depending on the brand, country of origin and technical specifications.
Diamond drilling machine design:
The diamond drilling rig is powerful and heavy professional tool for drilling deep holes of medium and large diameter in high-strength materials, which consists of a motor, rack and set additional equipment and tools (crowns, extensions, etc.). Typically diamond drilling machine has in its design a mechanism for supplying water, which cools the segments and the crowns themselves, extending their service life. The diamond drilling rig can support both dry and wet drilling. Professional diamond drilling rig allows drilling to be carried out regardless of whether there is reinforcement in the concrete or not. The only difference in performance is that if there is a large presence of reinforcement, the process will proceed somewhat slower, but the result will still be achieved.

Diamond drilling rigs are designed for drilling holes in walls made of high-strength materials, marble, hard natural stone or reinforced concrete with a high degree of reinforcement. Drilling machines allow you to drill not only on flat, but also on embossed surfaces, at almost any angle. For cooling work surface water is used between the crown and the material being processed.
Diamond drilling has a very low level of dynamic loads and vibrations. Thanks to this, the structure of the material in which drilling is carried out is not disturbed, and at the time of completion of the process it is not damaged external finishing walls. After drilling, no unnecessary cracks form in the wall, and the drilled core remains inside the crown and does not fall out onto the street with the risk of getting into the hood of someone’s car.
It takes 10-15 minutes to attach the drilling rig. The machine is secured anchor fasteners, or using a vacuum plate if it is not possible to use anchors. The material can be anything: brick, concrete or marble. A large number of reinforcement in reinforced concrete will not interfere with drilling and will not affect the quality of the finished hole, but will only affect the overall working time. You can find out the cost of services on the “Prices for diamond drilling” page.

- high positioning accuracy
- low tool wear
- low energy and resource costs
- External wall decoration is not damaged
- no surface post-treatment required
- the core remains inside the crown, there is no debris
- minimum noise, dust and vibration
Dry diamond drilling
It is used where it is not possible to use water for cooling, for example, where there is a risk of flooding the lower floor, in rooms where Finishing work, next to the power grid. To collect dust, it is connected to the drilling machine industrial vacuum cleaner. When dry drilling, the speed of work is lower, and wear cutting tool higher, so the cost of work is higher.
Dry drilling, video:
Deep Diamond Drilling
Drilling machines allow you to drill holes up to several meters deep. First, a hole is drilled to the depth of the crown, and the core is knocked out. Then a crown with an extension is installed, the core is knocked out again, and another extension is installed. And so on until the desired depth is reached.
Angle drilling
Holes can be drilled not only perpendicular to the surface, but also at an angle to it. In this case, the diamond bit wears out more, and the work speed is lower, so the cost of such drilling is usually higher.
Angle drilling, video
Drilling openings
Often, for various reasons, it is impossible to make an opening with help diamond cutting, For example:
- limited space
- low power electrical network on site
- lack of running water
- cuts from a large disc can change bearing capacity reinforced concrete structures
- large thickness of material, with small opening sizes
In such cases, you can drill an opening around the perimeter with a diamond core bit.

Diamond drilling of concrete has become widespread in construction. The technology has become popular due to its high efficiency. Since for the most part load-bearing frame modern building structures is monolithic reinforced concrete, others traditional technologies drilling under these conditions is ineffective. Even the most powerful hammer drill cannot compare with this method.
Today, diamond drilling of holes in concrete remains the most effective for obtaining through or blind holes in reinforced concrete walls, and if they are saturated with reinforcement, the only way. In addition to concrete, using this method you can work with such hard materials, like granite, marble, steel.
Advantages
Diamond drilling has many advantages over other methods:
- depth can reach 15 m;
- possibility of working at any angle;
- absence of dust and debris that are completely deposited by water;
- the possibility of drilling, despite the location of the reinforcement;
- high speed;
- absolutely accurate and round holes with runout up to 2mm and almost polished edges;
- during work low level noise;
- absence of vibrations that can lead to microcracks;
- drilling is carried out in vertical and horizontal surfaces;
- 220V mains voltage is sufficient to carry out the work;
- you can work in hard to reach places where it is difficult to apply traditional methods.
This method also has its disadvantages:
- expensive equipment requires very careful handling and maintenance by an experienced specialist;
- consumables should be changed periodically;
- water cooling the process flows onto the floor or along the wall and requires the use of additional drainage equipment.
Diamond drilling technology for concrete
Drilling is carried out by a powerful installation, which consists of a base, a stand, an electric motor and a drill bit. Diamond teeth are soldered to the base of the crown. They
consist of technical diamond crystals in a powdered metal binder.
During drilling, under the influence of high temperatures, the crown is transformed into a monolithic matrix, which can quickly and efficiently drill in the hardest material: reinforced concrete and granite are drilled equally well. Moreover, it is possible to drill in brick, foam concrete and other traditional building materials. The speed of drilling and its great accuracy, with ideal positioning relative to the markings, the evenness of their geometric dimensions and other characteristics distinguish diamond drilling from traditional, but outdated methods.
Diamond drilling is a non-impact method that compares favorably with jackhammers. To carry it out, it is enough to have at hand a regular household electrical outlet with a voltage of 220 volts and a source of water. The water cooling the working tool is collected immediately using an industrial vacuum cleaner.
Stages
- The location of the work, the location of communications, electrical wiring, pipes, etc. are being studied.
- Selected optimal size crowns, the center and contours of the hole are determined.
- The frame is attached.
- An installation with a crown is mounted on the base.
- The structure is checked for play. The fixing elements, crown fastening, and bed carriage are inspected.
- The water cooling system is supplied and connected.
- Work is being done.
When may it be required
Drilling with a diamond core may be required both in an apartment in a multi-storey building and during construction country cottage. The minimum level of noise and dynamic shock influences allow you to work in residential buildings during reconstruction and renovation, and even in already renovated apartments. The technology can be used for:
- drilling holes in the foundation for ventilation or sewerage;
- installation of gas and heating pipelines;
- electrical wiring;
- installation of fire protection systems;
- air conditioning systems;
- installation of chemical anchors;
- installation of ventilation communications within the walls: pipes and sockets;
- installation of fences.
- other cases where precise drilling without dust and noise is required.
The method is used when the task is to make a hole with an accuracy of up to a millimeter. Vertical holes are made, for example, to install machines or secure supports to create a canopy, installation garden furniture etc.
During renovation residential apartments and offices, sometimes it is necessary to break through a new opening. During the renovation process, sometimes it becomes necessary to change the layout, within which you need to make a door or window opening. A series of holes can be made to form one large one or even an opening of any shape.
Diamond drilling of holes in concrete - prices
The price of diamond drilling depends on the diameter of the hole and its width. The cost is calculated by centimeters. The cost of the order is also influenced by the following factors:
- drilling at height;
- at non-electrified facilities;
- saturation of reinforced concrete with reinforcement;
and some other possible factors.
