Tools that provide high-quality drilling holes in concrete

Concrete and its type - reinforced concrete, are durable materials that are not so easy to drill. The reason is their structure and fillers used. The tool at work constantly bumps into gravel or metal reinforcement, which are often an insurmountable obstacle to the drill or drill. Therefore, the cost of drilling holes in concrete depends on many factors.

Tools for work

Punch drill

The capabilities of the drill in drilling holes are not limitless. Usually they are limited by the maximum diameter of the device, which does not exceed 50 mm. Well, most perforators for personal and professional use can make a hole of no more than O30 mm.

Of course, sometimes this is enough, but sometimes not. For example, the size of the hole for the ventilation pipe should be larger, so the usual punch in this situation is not an assistant.

Another difficulty that you may encounter when drilling concrete with your own hands is fittings. Most often, the drill burns, bumping into the metal. Well, and if all the same it was possible to pass fittings on a tangent, the tool is simply clamped and it becomes impossible to drill further.

Tip: for proper marking it is best to use laser equipment.

Certainly, reinforcement is too serious an obstacle for it, which is almost impossible to overcome. In all other respects, the drill appears to be an excellent tool for effectively making holes in concrete surfaces.

Carbide crown

Such a device is capable of making holes from 50 to 450 mm. However, the capabilities of the standard perforator do not allow supplying it with a crown with a diameter exceeding 250 mm due to the lack of power. For larger openings, other equipment must be used.

The large ones have slightly different shank designs. But there are various adapters that allow the use of large crowns on low-power perforators. However, this is not the most correct way out, because the tool can fail if you supply it with a crown of too large a diameter. In addition, drilling holes in this way is not the safest job.

Pobedit crown on concrete has only two drawbacks, but they quite significantly limit the possibilities of this tool:

1. She passes in front of the armature. When colliding with it, the teeth deteriorate and break. Thin rebar can still be cut due to the large amount of carbide tack, but it is unlikely to be able to cope with thick.
2. When using a crown, the drilling depth of the concrete is limited. It is, as a rule, limited by its cup. With this statement it is possible to argue: if desired, such a tool can also be used for through holes in fairly thick walls.

The essence of the process of making through holes a crown is to alternately use it and the peak on the punch. Having deepened to the distance accessible to the crown, you need to knock out the core of the hole with a lance, then repeat the action, and so on until the very end.

But there is another depth limit due to the length of the peak itself. Although the problem is solved by installing an extension cord on the crown. It should be remembered that the process of drilling concrete with such a tool is a job in which a lot of dust is emitted.

In the end, it will be as long as difficult. It is better to use another tool for this, which will be discussed below.

Diamond crown

Diamond drilling holes in concrete in our time has become the widest distribution in the economy, and in construction, and this is no accident.

There are a number of reasons for this popularity:

1. This tool, which effortlessly copes with concrete, and with reinforcement, found in almost any concrete structure. After all, a diamond, even grown artificially - one of the hardest materials in nature.

   

1. It has a tubular design that allows you to go deep into the concrete at almost any distance in one go.. After drilling, a single, one-piece concrete rod is simply removed from the wall.
2. Another design feature is water cooling.. Thanks to him, no dust is generated at work, which is undoubtedly a great advantage.
3. The tool provides unparalleled drilling accuracy.. If the crown diameter is 250 mm, the resulting hole will be exactly the same size. No errors arising from the beating, is not formed due to the special tubular design of the device.

Admittedly, there is a drawback - this is the price that has to be paid for efficiency. The crown itself is worth a lot, and the instrument can hardly be called cheap, but this does not apply to small-diameter crowns, which are used to work with tiles or drilling podrozetniki in concrete.

They are installed on conventional perforators or drills that do not have water cooling systems, and are limited in depth due to the size of the body. Here we are talking about a diamond storm, which makes it possible to make holes in concrete surfaces at almost any angle.

In addition to all the benefits, it is also excellent for working with other materials. For example, the instruction allows you to use it on a brick, which it passes through as oil. Stoneware and granite, which are too tough for other tools, are also drilled without any effort.

Advice: if you need to cut a reinforced concrete structure or make a shter in it, the cutting of reinforced concrete with diamond circles of necessary strength is used.

Conclusion

Holes in concrete structures - a necessary stage in almost every repair. For this purpose, various equipment is used, among which diamond drilling stands out, which can easily cope with any building materials. In this case, use special crowns and equipment.
