Diamond drill bit for concrete - choice and use

Diamond processing is most effective for treating concrete. For example, diamond cutting and drilling of concrete are widespread. The only tool in this case should be of the highest quality and appropriate for its tasks, so in this article we will look at how to choose a drill bit for concrete and with what equipment it can use.

General information

A diamond drill is nothing but a drill bit. Externally, it is a hollow tube. On one side is a working part with weld segments, and on the other side is a fastening mechanism (flange with shank).

Application area

With this tool you can get round holes of different diameters and a depth of one and a half meters. I must say that crowns exist for the treatment of various building materials, including work on brick, reinforced concrete or even natural stone.

As a rule, diamond drilling of holes in concrete is especially important in the following cases:

• When laying engineering communications;
• When installing heating or plumbing equipment;
• Laying cables, extension cords, etc.

It should be noted that diamond drilling of concrete can be used not only for industrial, but also domestic purposes. For example, this procedure can be used to install internal outlets in concrete walls, junction boxes, etc.

Some crowns do not require special professional equipment. They can be used with a conventional household electric drill or perforator.

Virtues

Among the advantages of the considered technology are the following points:

• Diamond drilling of holes in concrete is performed with high speed and performance.
• Holes are obtained with a smooth surface and precise dimensions., which eliminates the need for additional processing.
• Low vibration and dust free (when working with a professional tool).
• Ability to work in confined spaces or hard to reach places. In particular, the work can be carried out close to the surface of the floor, walls, ceiling or at an angle to the treated surface.
• Drilling does not damage the supporting structure, in particular, does not cause chips and cracks.

Thus, if it is necessary to make a hole, the application of this technology in some cases is the most expedient solution.

Crown selection

When choosing a drill, you need to pay attention to a number of factors. First and foremost, of course, is its diameter. It must correspond to the required hole diameter. For example, if you need to install an outlet with your own hands, then, accordingly, the crown should correspond to the diameter of its mounting mechanism.

In addition, you need to pay attention to:

• The material to be processed. For example, it can be ordinary concrete or reinforced. It can also be fine-grained, or contain gravel.
• Fastening mechanism - the crown should fit the tool without backlash.
• The power for which the crown is designed must correspond to the power of the power tool.
• The drilling rate, which is designed for - as a rule, is within 10 mm / min - 60 mm / min.
• Resource tool.
• The possibility of recovery - if the nozzle can be restored, then this will reduce costs, since the price of a quality product is quite high.

Note! During the drilling process, diamond bits for drilling concrete gradually wear out. Therefore, the diameter of the drill should be slightly larger than the diameter of the pipe that will wind up in the hole.

But the most important thing is that the drilling of concrete with diamond crowns is effective and safe, the nozzle must be reliable and of high quality, corresponding to the characteristics declared by the manufacturer. Therefore, it is necessary to purchase products from reputable, trusted manufacturers.

Crown restoration

As mentioned above, crowns can be restored after prolonged use. For this there are special repair services. The restoration of the instrument takes place in several stages.

First of all, experts determine how much the drill is worn out and whether it is possible to restore it at all. If, after a detailed study, it turns out that the body does not have horizontal beats and the instrument as a whole is in a normal state, then the working segments are soldered.

In order for the instrument to be restored, the instruction must be followed during operation. In addition, you must ensure that it does not overheat.

Note! In addition to drilling, it may be necessary to cut reinforced concrete with diamond circles. In this case, you also need to use a special tool that meets certain conditions.

Drilling equipment

As mentioned above, you can perform small holes with household tools. However, when it is necessary to obtain holes of large diameters, for example, in a reinforced concrete structure, it is necessary to use special equipment for diamond drilling of holes in concrete.

All existing installations are distinguished by the following features:

• Engine power –from this indicator depends on the duration of continuous operation of the device. In addition, the engine power is interconnected with the weight of the equipment and compactness, the larger it is, the more, respectively, the weight of the device.
• The method of mounting the frame (engine support) - in the method of mounting, the existing installation are of two types:

• Fixed with anchors. This mount requires additional holes in the wall.
• Fixed with a spacer bar, which rests on the floor and ceiling.

Considering all these moments, it is necessary to choose a machine for diamond drilling of holes in concrete in accordance with the conditions and type of work to be performed.

Conclusion

Using a diamond drill is the most effective way to drill reinforced concrete and other durable building materials. The only thing you need to choose the right tool to its characteristics match the conditions of work.

In addition, you should follow some operating rules that will allow you to restore the erased tool in the future. You can get additional information on this topic from the video in this article.
