Diamond disc for concrete for Bulgarian: overview, specifications and reviews

A diamond disc for concrete can be used if it is necessary to cut a stone, a brick, or a tile. It is used as an expendable material for angle grinders, concrete cutters, shtoborezov and stationary cutting machines. On the market today, you can meet in a wide variety of diamond discs for concrete imported and domestic manufacturers.

Characteristics

Diamond disc for concrete has one important advantage, which is expressed in saving time for work, as well as high durability. If we compare this consumable material with abrasive analogues, then the first one is more effective, does not last long and is able to maintain the depth of cut throughout the life of the tool. A diamond disc for concrete, as a rule, is a metal circle, on the edge of which diamond tools are soldered. For fastening, laser welding is used, and the cutter is made from a mixture of metal binder and diamond powder by pressing technology. The circle itself is made of very strong tool steel.

Overview of varieties of diamond discs

The diamond disc for concrete can be represented by a segment circle and is designed for dry cutting. Endless disks are used for "wet" cutting, on the market you can find products for reinforced concrete and grinding diamond disks. The latter are used for grinding stone and concrete surfaces.

Characteristics of segment circles

On the body of such an element, there are sectors, between which are technological slots. The latter are necessary to reduce the stress of the cutting edge, to linearly expand the body and improve heat removal. These grooves are also used for the removal of cutting waste. The technological slot can be based on a radial bore, which is capable of more efficiently distributing impact loads when cutting concrete. In this case, you can eliminate the overstrain of the body of the circle.

Endless Drive Characteristics

An endless diamond detachable disk for concrete is used for "wet" cutting, it does not have cuts of the working edge, and along the radius there may be holes that are necessary for the distribution of voltage. As a mandatory condition for the operation of such an element is the supply of water.

Review of disks for reinforced material and grinding diamond disks

Diamond disks for cutting concrete can be used for reinforced material, they have the maximum possible thickness of the body and a larger content of the diamond component. Grinding discs are used for grinding concrete, as well as stone surfaces. During their manufacture, a diamond layer is applied to the surface, which is located on the ring skirt. It is visible on the edge of the circle and is called a cup. Disks that can be used for sanding concrete surfaces have a rather complex device: they consist of a main disc, on which grinding cups are fixed in a certain amount.

Dimensions

A diamond disc for concrete for a Bulgarian has certain dimensions, which are indicated in the marking. Looking at the alphanumeric designation, you can find out the width of the cut, the diameter of the circle, and the diameter of the hole. If we are talking about the product Hilti DC-D 125/22 UP, it can be argued that the figure 22 indicates the diameter of the hole, while the diameter of the circle is 125 millimeters. The width of the cut is not indicated here, this indicates that it is minimal. Most often the mention of width is a marketing move by which the company wants to emphasize that the disk has an impressive width, and therefore, high strength. However, this has nothing to do with reality. The diameter of the circle can vary from 200 to 600 millimeters, but products characterized by a diameter above this value are used for production purposes, for example for cutting marble. When carrying out construction work, such circles are not applied.

Custom sizes

Foreign manufacturers offer on sale disks with the sizes which are non-standard. Over time, domestic factories adopted this trend. These are circles whose diameter is 115 or 230 millimeters. State standards do not fix the dimensions of such products. That is why plants are developing their technical documentation, which is acceptable.

Cost depending on quality and size

If you need a diamond disc for a concrete grinder, the price of which will depend on the segment and size, you must determine what quality will be acceptable for you. Thus, with a diameter of 115 millimeters, the budget variant of the diamond disk will cost between 90 and 120 rubles. For the average quality of the disc of the same size, you will have to pay about 280-340 rubles. The premium quality of the products on sale will cost about 480 to 620 rubles. With an increase in diameter to 125 millimeters, the budget variant will cost 195 rubles, as for the average variant, then it will have to pay 400 rubles for it.

The maximum possible price for premium quality is 1200 rubles. With an increase in the diameter of the disc to 250 millimeters, the lowest quality will cost 800 rubles a maximum. With an average disc quality, the manufacturer asks for a cost of 2900 rubles. For products of this diameter, the highest class will have to pay 3,500 rubles. It is noteworthy that if you choose a 450-millimeter circle, then you will not find a bad quality. On sale are cutting elements of the middle and premium segments, their cost is 5400 and 11 000 rubles. respectively.

Reviews about the field of use

If you need a diamond disc for concrete, the price of which was mentioned above, then you only need to purchase the products after you have decided on the conditions under which they will be used. The expected scope of work is also important. As users emphasize, the 125mm disk is great for working in the premises, but to avoid running into the store in the middle of a working day, it is best to have 2 cutting tools in stock. If there is a need to work with jumpers of openings and other concrete elements, then it is best to stock up to 150-230 mm discs. As the experienced masters emphasize, they are most suitable for panel-type buildings. With their help, you can, for example, align the escarpment. For one brigade, it will be sufficient to have 2 such disks, but for repairing an apartment or a house, 10-20 such cutting elements will have to be stocked.

Quality Reviews

In the opinion of many foremen, it is best not to use cheap disks, since such an acquisition can not be called beneficial. This is confirmed by practice. Such products are quickly erased, which leads to the need to acquire new ones. When performing work for one object such a disk will be enough, it may suffice for subsequent manipulations. Everything will depend on the specific volume. If you use a disk for domestic purposes, then it can last for a long time, in another case it is in the building organizations.
