Diamond Tool, Drilling And Cutting Concrete With Its Help. Myths and Reality

We discard several myths about diamond drilling and cutting concrete (reinforced concrete) with a diamond tool.

Diamond cutting is silent

Of course, in terms of noise performance in comparison with the shock method, diamond cutting and drilling produce less noise, but there is no need to talk about its total absence. Cutting the walls with a diamond tool is in any case a mechanical effect, accompanied by a noise of the engine running (especially when it is felt by the petrol cutters), the noise of the rotation of the cutting element (whether it's a diamond disc of a wall saw or a drill bit of a diamond drilling rig), the diamond edge contact noise With the surface (especially when passing through the reinforcement layer). Therefore, to disturb the noise of neighbors during the repair or redevelopment still have to.

Wet drilling and concrete cutting in residential buildings is fraught with flooding

When replanning and repairing in private apartments, residents often choose between diamond drilling technologies, tend to dry drilling, for fear of flooding both their own apartment and neighbors from the bottom. However, in carrying out such work, drilling or cutting of structures, with a thickness of 300-400 mm, is most often required, and manual cutters that do not require the consumption of large volumes of water can easily cope with this. If the work requires the use of powerful drilling rigs or wall saws, the use of a professional tool makes it possible to use a water collection vacuum cleaner that prevents water from entering the floor.

Myths about diamond discs

The more diamonds, the better the diamond disk

In fact, the number of diamonds, as well as their size depends directly on the destination of the disc. So, for example, diamond disks intended for cutting granite have a smaller amount of diamonds, but they are larger and wear out more slowly. A large number of small synthetic diamonds are soldered onto a diamond tool (cutting circle) for concrete.

The higher the stiffness of the segment bundle, the better

The rigidity of the bond is determined by the purpose of the diamond disc. From the optimally selected stiffness of the bundle, taking into account the abrasiveness of the material being processed, the operating life of the cutting disc will depend. Too tight a bond will result in salting (the bunch wears out more slowly, the diamonds are barely exposed, the productivity falls). Too soft a bundle will wear out faster than diamonds, which will lead to the fact that they, without having worked out their resources, will fall out.

Thus, the diamond tool is , of course, an advanced and high-performance technology that is used for drilling and cutting concrete, but at the same time it is far from cheap. Therefore, in order to fully utilize its resource, it is necessary to carefully treat the selection of the tool and its operation.
