Complete information about perforators

We have repeatedly discussed the importance of modern tools in the construction process.

In this blog, we will talk about the perforator, explaining interesting details and features of the tool.

What is a perforator and how does it work?

A perforator is an electric tool that has an impact mechanism and drilling capabilities. The tool is universal in that it combines various drilling mechanisms. That is why it has become indispensable in construction, repair, decoration and other types of work.

Since the use of a perforator depends on individual needs, you may need it for household or professional work.
Thus, you can choose the option you want.

Depending on the weight, there is a division of the tool into three classes:

Lightweight - weight not more than 4 kg. Power - from 400 to 800 watts. Mainly used for household repair work, when it is necessary to drill small holes.
Medium - weight up to 8 kg, power - up to 1000 watts. These models are used for decorating, performing minor repairs and electrical work.
Heavy - exceeds 8 kg. Power - up to 2000 watts. Such models are used by professionals during dismantling, repairs, laying cables and removing materials.

Depending on the class, models may differ in external and internal structure. It is worth noting that models have different engine layouts. For example,

Vertical design: It is quite compact and convenient to use. In addition, the vertically positioned motor cools more easily, which allows it to withstand heavy loads under operating conditions, especially in impact mode.
Horizontal design: Anyone who has a low-power hammer drill in their home tool kit is most familiar with this type of hammer drill. In addition, since tools vary in speed, manufacturers specifically use metal parts.

Types of impact mechanism:

Electromechanical - when pulling, a lot of effort is required, which means that the engine power should be as large as possible. Due to overload, the impact force increases, which is transmitted to the equipment. However, since models with this mechanism are already considered obsolete, they are no longer on sale.

Electropneumatic - allows you to get a high-impact blow, even with low energy. This is a very popular mechanism that is used by almost all manufacturers.
Main features of the perforator:

Power:

For different models, depending on their class, the power varies from 400 to 2000 W. For household work, 400 to 500 W is sufficient. And for tools that need to break down large-diameter foundations, it is important that they have a power of more than 1000 W.

When choosing, you should consider the density of the materials you need the tool to process. High impact force is needed for processing concrete, reinforced concrete, and stone. But this will be detrimental to easily brittle materials, as cracks may appear during their processing.

Weight:

When choosing perforators, you should not be guided by the usual rule of "the lighter the better." As we mentioned at the beginning of the blog, the division into classes is also done by weight, and the heavier the tool, the more productive its performance.

Models weighing more than 8 kg are used during renovation and construction.

For home use, it is not necessary to purchase a heavy and massive drill. Light-duty tools weighing up to 4 kg can easily be used for home conditions.

How to use a perforator correctly, basic rules of operation:

Do not use a hammer drill on cracked or newly constructed floors. If you have to work at height, make sure that the ladder or steps are secure.

Try to work with both the primary and secondary handles. If the drill bit gets stuck in the material, the tool may become uncontrollable, which can backfire.

Working with high-quality and well-maintained equipment eliminates the possibility of interruptions and improves the quality of work.
Use protective equipment - concrete fragments may get in your eyes, so wear goggles.

Concrete dust is dangerous for the lungs, so you should use a special mask for this. Headphones will protect you from the noise.
