A diamond blade for concrete can be used if necessary cutting stone, brick, and tile. It is used as a consumable for angle grinders, concrete cutters, chippers, and stationary cutting machines. In the market today you can find a huge variety of diamond wheels for concrete imported and domestic manufacturers.
Specifications
A diamond blade for concrete has one important advantage, which is expressed in saving time for work, as well as high durability. If we compare this consumable with abrasive analogues, then the first is more efficient, does not grind for a long time and is able to maintain the depth of cut throughout the entire period of use. A diamond blade for concrete, as a rule, is a metal circle at the edge of which diamond tools are soldered. Laser welding is used for fastening , and the cutter is made of a mixture of a metal binder and diamond powder by pressing technology. The wheel itself is made of very durable tool steel.
Diamond Wheel Variety Overview
A diamond blade for concrete can be represented in a segmented circle and is designed for dry cutting. Endless disks are used for wet cutting; products for reinforced concrete and grinding diamond disks are on sale. The latter are used for grinding stone and concrete surfaces.
Segment Circle Characteristics
On the body of such an element there are sectors between which technological slots are located. The latter are necessary to reduce the stress of the cutting edge, to linearly expand the body and improve heat dissipation. These grooves are also used to remove cutting waste. A technological slot can have a radial bore based on it, which is able to more effectively distribute shock loads when cutting concrete. In this case, you can eliminate the overstrain of the body of the circle.
Infinite Disc Characteristics
An endless diamond cutting disc for concrete is used for wet cutting, it does not have cuts in the working edge, and the holes that are necessary for voltage distribution can be located along the radius. A prerequisite for the operation of such an element is the supply of water.
Overview of Reinforced Blades and Diamond Grinding Discs
Diamond blades for cutting concrete can be used for reinforced material, they have the maximum possible thickness of the body and a higher content of diamond component. Grinding discs are used to grind concrete as well as stone surfaces. In the process of their manufacture, a diamond layer is applied to the surface, which is located on the annular skirt. It is visible along the edge of the circle and is called a cup. Disks that can be used to grind concrete surfaces have a rather complicated device: they consist of a main disk on which grinding cups are attached in some quantities.
Dimensions
A diamond blade for concrete for a grinder has certain sizes, 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, as well as the diameter of the bore hole. If we are talking about the product Hilti DC-D 125/22 UP, then it can be argued that the number 22 indicates the diameter of the bore, while the diameter of the circle is 125 millimeters. The width of the cut is not indicated here, this suggests that it is minimal. The most common mention of width is a marketing ploy, with which the company wants to emphasize that the disk has an impressive width, which means high strength. However, this has nothing to do with reality. The diameter of the circle can vary from 200 to 600 millimeters, however, 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 discs with sizes that are non-standard. Over time, domestic factories adopted this trend. We are talking about circles whose diameter is 115 or 230 millimeters. State standards do not record the size of such products. That is why factories are developing their technical documentation, which is permissible.
Cost depending on quality and size
If you need a diamond blade for a grinder for concrete, the price of which will depend on the segment and sizes, you must determine what quality is acceptable for you. Thus, with a diameter of 115 millimeters, the budget version of the diamond disk will cost between 90 and 120 rubles. For the average quality of a disk of the same size, you will have to pay about 280-340 rubles. The premium quality of the products on sale will cost approximately 480 to 620 rubles. With an increase in diameter to 125 millimeters, the budget option will cost 195 rubles, as for the average option, you will have to pay 400 rubles for it.
The highest possible price for premium quality is 1200 rubles. If you increase the diameter of the disc to 250 millimeters, the lowest quality will cost 800 rubles maximum. With an average disk quality, the manufacturer asks for a cost of 2900 rubles. For products of this diameter of the highest class will have to pay 3,500 rubles. It is noteworthy that if you choose a 450 mm circle, then stumble on poor quality will not work. On sale are cutting elements of the middle and premium segment, their cost is 5400 and 11 000 rubles. respectively.
Use area reviews
If you need a diamond blade for concrete, the price of which was mentioned above, then you need to purchase products only after you decide what conditions will be used. The expected scope of work is also important. As users emphasize, a 125 mm blade is great for indoor work, however, in order not to run to the store in the middle of the day, it is best to have 2 cutting tools in stock. If there is a need to work with lintels of openings and other concrete elements, then it is best to stock up with 150-230 mm disks. As experienced craftsmen emphasize, they are most suitable for panel-type buildings. With their help it is possible, for example, to level the slope. For one brigade, the presence of 2 such disks will be quite sufficient, but 10-20 such cutting elements will have to be stocked up to repair an apartment or house.
Quality Reviews
According to many team leaders, it is best not to use cheap discs, since such an acquisition cannot be called profitable. This is confirmed by practice. Such products are erased quite quickly, which leads to the need to acquire new ones. When performing work for one object, such a disk will be enough, it may be enough for subsequent manipulations. Everything will depend on the specific volume. If you use the disk for domestic purposes, then it can last for a long time, the situation is different in construction organizations.
