Final prices for cutting concrete with a diamond blade
Thus, the consumption of grinding wheels per 1 m2 for wood will be slightly lower than the same figure for metal.
Exact standards can be calculated experimentally for a specific material by determining the grinding area that can be completed before signs of wheel wear appear. Grinding wheel wear is determined visually - by the presence of destruction or damage on the surface of the material. For wheels with a self-sharpening function, grains with a worn upper edge are removed and the load falls on the unworn elements. Accordingly, such wheels have slightly lower consumption than those that do not self-sharpen during operation.
Primary wear occurs most intensively when a newly installed grinding wheel grinds against the surface upon first use. This period takes a very short period of time. If there are signs of wear, it is ineffective to use the wheel without correcting it.
A worn wheel has dull edges of the grains. Editing effectively solves two problems at once:.
How long does a grinding wheel last?
Editing can be done in a variety of ways. These grains are attached using a special metal bond and allow the surface to be processed, achieving a slight roughness. If we talk about the processing of which material diamond cutting is most often associated with, then concrete will always come first. It is easier to name where it is not used than the entire scope of application of concrete and its derivatives.
Laying the foundation, walls and interfloor ceilings - almost every construction project cannot do without it. Moreover, to obtain greater reliability of the buildings being erected, concrete reinforced with steel reinforcement is used. And such concrete is filled with sand or fireclay stone - further enhancing its strength.
Consumption of diamond discs
If reconstruction or dismantling of the structure is necessary, this strength makes the work difficult. Here diamond cutting is the way out.
But we are not talking about a diamond in the usual sense. Its artificial analogue is used - fionite. Its hardness and strength are identical to real diamond, and such material costs much less.
Modern diamond cutting technology uses several equipment options. The principle and design of the diamond cutting tool depends on the task. If you need to cut a relatively small opening in a concrete wall, a diamond blade on a hand-held cutter will cope with this task.
Concrete cutting methods
Dry cutting
This type of cutting is carried out without the use of water using the latest equipment. Sturdy diamond wheels will be necessary as they do not require refrigeration. This method of carving is used in the first stages of building construction, before water, electricity and other communication systems have yet been installed in the room.
Dry cutting is not necessary if the work is carried out in residential, enclosed spaces, as it is accompanied by noise and some dust. That is why this type of cutting is used in new buildings and non-residential premises. This method is also good when you need to cut a small opening. The only disadvantage of dry diamond cutting is the low speed. Every 3-4 minutes the instrument has to be given time to rest and cool down. If this is not done, the equipment may break down within a short period of time from the start of its use.
Wet cutting
It is used in cases where work is carried out in residential buildings and premises and if it is necessary to make a hole in the wall deeper than twenty centimeters. There is a large selection of different tools for this type of cutting. If you choose equipment with a small water supply, you can work without worrying about the finishing and floor coverings. Drilling with diamond wheels occurs with a segmented drill of a certain diameter, and if it is increased, the water consumption will also increase because it does not need to be cooled. For more serious work, more serious equipment and machines are used. In this case, it is possible to work without dust and increase the speed of the process.
Diamond cutting disc
As for the operating principle of the cutters, they can be gasoline, electric and hydraulic. The electric cutter is equipped with a diamond blade with a maximum diameter of mm. This is enough to make a mm deep cut on one side. If exactly the same on the other, the desired result is mm. However, for the second side you will need to install a new disk. Hydraulic hand cutters have more power: the disc can have a diameter of up to mm, the cutting depth on one side is mm, and the same on the other.
To operate such a cutter, an oil station and a voltage of volts are required. Gasoline cutters differ from others in that they must work only in open space, in the fresh air: their power unit is a gasoline engine.
Approximate calculation of diamond blade life
Manual diamond cutting can also be done using chain saws. Then a cut of up to mm on one side is possible. But there is one significant drawback: using chain saws today is unprofitable due to the established prices for cutting concrete. Hand tools are used when the scope of work is small - for example, openings in the wall in residential premises, that is, where a wall cutting machine cannot work. A wall saw, a rope saw and a joint cutter are special equipment designed for diamond cutting of structures, thick walls and road surfaces or for their destruction.
A distinctive feature of such equipment is high power and high productivity. The installation of a wall saw is quite complicated: a special guide is needed. But the cut with its help reaches a depth of mm on one side.
If dismantling of a massive reinforced concrete structure is required, a rope machine is used. It can handle any thickness. When reconstructing various buildings, it is difficult to do without diamond cutting of reinforced concrete. If you are planning to remodel your apartment and need one or more additional openings in the wall, then diamond cutting will be very helpful. But it is often used during the construction process.
Let's say a defect was discovered during the pouring of concrete structures. Diamond cutting can fix this. Or when demolishing a concrete building, when it is impossible to use heavy construction equipment.
The sequence of work on an opening in a concrete wall follows a certain order. First, a thorough marking of the future opening is carried out, its contours are indicated. If necessary, it is necessary to determine where the steel reinforcement goes.
Often during renovation, construction or demolition of houses, cutting of a concrete wall is performed. Nowadays this is done in different ways: using an oxygen lance, a water jet, or a diamond tool.
When working with a thick wall, when you cannot do without a wall saw, guides and motors are installed. Diamond discs are mounted on their axes.
Since in this case, concrete cutting involves heating the tool to a high temperature, water is needed to cool the tool. Its quantity is from 4 to 10 liters per minute. Water not only cools the cutter, but also removes the resulting crumbs and dust. This extends the life of the tool and speeds up the cutting process.

What is the service life of diamond blades?
When using a wire machine, additional rollers are required: they serve as guides for the diamond wire. The cut wall mass should be laid on the floor, covering that place with shock-absorbing material. These could be car tires or something similar. Any diamond cutting method will have an advantage over other options used to establish openings or dismantle a concrete structure.
First of all, this procedure is less or completely dust-free thanks to the water that is required by the cutting technology. In addition, diamond cutting has a much higher speed than, for example, a hammer drill. Plus - the absence of destructive impact force, which can be dangerous in a building in use.
Another advantage is the quality of the cut. Its edges will not require additional processing; they will be even and smooth. And all dimensions are accurate, corresponding to the intended contour. It is also important that, if necessary, you can work only on one side of the wall, making a planned cut on it.
It will not spread to the other side. Although diamond cutting cannot be considered inexpensive in terms of cost, with the correct estimate, when all the costs of dismantling or installing new openings and holes are summed up, the economic effect will come from this method. Another clear advantage is maximum structural safety of the entire building. There is no impact force that can cause damage to the structure: cracks and chips will not appear in concrete and reinforced concrete.
There will be no noise that accompanies the operation of a hammer drill or jackhammer. And this is not the whole range of work that a diamond cutter can handle. And it can cope with almost any material, no matter how thick and hard it is. Thus, you need to make a cut on one side of the wall one hundred and forty millimeters thick, then move the markings to the other side and make a cut towards it. Petrol cutters with a diameter of four hundred are noticeably more expensive when purchased.
The undoubted advantage of the gas cutter here is maneuverability, but the disadvantage is that it is more difficult to maintain the line, especially on the upper horizontal cuts, and most importantly - the exhaust, which is why working in enclosed spaces is only possible in respiratory and eye protection and using exhaust exhaust hoses.
Tool shape and size
The parameters of the tool and consumables suitable for the job should be taken into account at the time of purchase.
The industry produces the following types of diamond cutting wheels for concrete for power tools :
- Round. They are designed for work on wet surfaces.
- Segmented. They are used for working with dry material.
- Grinding. These discs have grooves to remove dust.
The geometric dimensions of such products must comply with GOST. Finished products have a circumference of about 600 mm and a slot width of up to 3.5 mm. The permissible diameter of the mounting slot for these discs is no less than 15 mm.
Products with a circumference from 230 to 350 mm are considered to be the most popular among professionals. Discs with this diameter are used for laying main communications in buildings.
For cutting raw materials from reinforced concrete, concrete cutting discs are mainly used. They are also used for working with plastic and hard surfaces. Among the latter are :
- a natural stone;
- marble;
- granite;
- brick;
- reinforced concrete;
- composite products;
- lightweight concrete.

Now to the personnel issue. Working with diamond tools requires high qualifications. Attracting Russian workers for such work is low-effective for a number of reasons, and attracting foreign labor, although more effective in terms of productivity, presents a certain difficulty associated with the registration of workers.
One way or another, a self-respecting company pays the employee about a third of the total cost. We combine debit with credit. Two and a half meters of cutting cost at least 11 rubles minus rubles. RUB remains. Subscribe to answers. Sergey Hello, Ivan. As a rule, the resource is directly proportional to the cost of the disk, but there are exceptions.
Tudor Good afternoon, Egor! The diamond discs you are asking about are of two types: Turbo - Turbocharged diamond layer, height 12 mm, with a resource of meters depending on the brand of concrete, quantity and diameter of reinforcement.
And 1A1RSS - segmented, height 12 mm, resource meters.
How is this done?
Since certain types of discs are used for each tool and for different types of material, you can find a huge number of them on sale. How to choose the one that will provide the best quality when performing your work and will last longer than others? Our review will help you figure this out. But first, we will take a look at the factory for the production of diamond blades to find out how they work and what their features are.
The first stage of disk production is the production of diamond cutting segments. To do this, artificial diamond particles are combined with a durable polymer and pressed into a mold.
When the segments are ready, they are connected to the steel base of the disk. This happens by powder or silver soldering or laser welding. Such complex and expensive methods are used because the connection must be extremely strong and resistant to high temperatures.
After this, the cutting edges are processed with a ceramic sharpener. The sharpening is one-sided: in order for the disc to cut well, you need to observe the direction of rotation (it is always marked on the disc with an arrow).
Modern industry produces diamond blades of different diameters, with different sizes of mounting holes and with different cutting edge structures. The choice depends on the type of tool and the material to be processed.
Remember safety
Diamond tools can cause serious injury if used without proper safety precautions. Always use a respirator and safety glasses when diamond cutting any materials (they will protect you from dust and particles). Be sure to put a protective cover on the tool if it is provided by the manufacturer. Do not allow the disc to overheat - it may burst and injure others with fragments.
Following these simple rules will help you get the job done effectively without risking your life and health.
Processing tools
The grinding disc has special cups that ensure grinding of the material. A layer of diamond coating is applied along the edge of the circle. The structure of the described disk is more complex compared to other types. It is this special configuration that allows the processing of hard rock materials. Special grooves that separate the grinding cups protect from dust during processing.
Diamond coating has a higher level of durability, which allows the tool to last much longer than other types of discs.
Features of the work
Regardless of the cutting method, it must be remembered that making holes and channels in solid materials requires strict adherence to safety precautions. For independent use, it is better not to choose high-power tools with cutting discs over 230 mm. Such equipment requires well-honed skills and relevant experience.
For home use, it is best to use hand cutters and electric devices with discs from 125 to 230 mm. But professional tools require more serious cutting elements with a diameter of 230 – 350 mm.
Diamond cutting allows you to quickly and efficiently create any hole or channel in high-strength materials. If you don’t forget about safety precautions, working with such a tool will make the life of anyone faced with repairs or finishing significantly easier.
Who cuts monolith, reinforced concrete with what? Today in the Store they showed some diamond discs 125 for 800 rubles, they said they are used by rescuers in Germany, they say they are not afraid of reinforcement or anything else. I rented a concrete diamond cutter for just 160 rubles. How do you cut? What is the best thing to take?

Well, how about the turbo Hammer Dia? special for reinforced concrete Do you think bikes? Doesn't it make sense to buy such discs? How do you cut reinforced concrete and monolith yourself?
Yes, I cut all sorts of things. hurricane, bieber, etc. and so on. I tried the Khitachev ones - they left some controversial sensations.
things don’t live on the fittings) I wonder if these discs really aren’t afraid of it..

I just had a riot of plumbers - they didn’t want to cut grooves in concrete... So I’m preparing for the future to equip utility workers with equipment.
any disc wears down on reinforcement many times faster than without it. It’s just that these “times” are different for all discs.. I liked the spit discs on the wall chaser. I would choose branded Hilti wheels, sleep. cedima - if there is one.
jud-suss, well, 20 (or 22. which one is correct?) takes a long time to cut, and up to 1 cm with almost any disk without much loss of time.

Well, not everything can be bought in Volgograd) What is better to see, tell me?
Are the disks I linked to good? Any experience using them?
jud-suss wrote: Well, not everything can be bought in Volgograd)
Duck. What about online stores?
You write what to do, the amount of work - and then you can look at it, be it Bosch, Hilti, or anyone else.
jud-suss wrote: Are the disks that I linked from the links good? Any experience using them?
Devolt can be trusted, Diam is another nonname, like Ketaya. I didn’t cut it with either one or the other - with boches, hilties, milks, whatever you like. You can also look at the discs on Boschbuy www.boschbuy.ru The only thing is that I would stay away from the ketai/local basement, if it’s not for nothing.
Tomorrow I will work with a Bosch Best for Concrete 230mm disc. I'll tell you later.
The scope of work is small, grooves in concrete, brick or plaster for plumbing and electrical installations. These are usually bathrooms. I want to take a couple of normal discs and not forget about the difficulty of cutting reinforced concrete
I'm interested in rationalism. Which option pays off better? 1 good disk or several ordinary ones? I also don’t really want to go to the fittings and change the disks.

Yes, concrete laps there cost 2.5 tr.. are they really worth it?
jud-suss, despite my sincere love for branded and expensive tools and consumables, I use the cheapest diamond blades. I buy Top Tools for 100 rubles, 2-3-4 disks are enough for a two-room apartment in a Soviet-built panel house. There are also slightly more expensive ones - Polish VERTO (120-140 rubles) - they can also work well. You can also buy Polish GRAPHITE for 250 rubles. If the resource of these pre-purchased disks is not enough, then it will not be difficult and unnecessary costs for the customer to purchase 1-2 more. I think this is the most acceptable option, because... I consider it simply inappropriate to buy a disk for $100, which I will only use 1/3 or half of and leave it to a customer who simply does not need it or buy it back at the residual value. My customers, in most cases, completely agree with me.
