The perforator allows you to easily drill a hole in the concrete. Without it, the repair can take away a lot of time and strength. Today, there are many different models of perforators in the instruments market, which in turn, makes the richer choice and at the same time it becomes more difficult. So how to choose a perforator?

This tool is a drilling machine with a longitudinally axial movement of the working body. Perforators are often confused with a shock drill. The difference is that the impact function is pneumatic, and not mechanical, like a drill. Thanks to pneumatics, the perforator is able to make holes in concrete, brick and stone.

What a perforator to choose

Classification

According to the functionality, the perforators are divided into the following types:

1. Single-mode - highly specialized tools. Not suitable for home repair needs.
2. Double-mode - more common tools. There is a shock and drilling mode or loaves.
3. Three-mode - in these tools there are all the above functions.

To work with a tree or metal, the drilling mode is usually used, with brick and concrete - drilling with a blow, and shock mode is most suitable for removing the tile.

Before deciding which perforator to choose for home or work, you need to decide on the required functionality, but it is better to take a tool with all three modes.

The performance of the perforator is made to judge in two characteristics - it is the power and impact force. Important moment: the impact force is not always proportional to the power.

Tools are usually equipped with two types of cartridges:

1. Ordinary.
2. Quick.

The most appropriate option for all cases is the second type of cartridges, which allows you to change the drill only with an effort of your hands without additional tools.

An important characteristic of the instrument that needs to be taken into account when solving the question, how to choose a perforator for the house is its weight. According to this criterion, the following classes of perforators are distinguished:

1. Light - no more than 4 kilograms and up to 700 watts. These tools are good in that it includes the SDS-Plus cartridges, with which you can use the browns with a diameter of up to 26 millimeters. A feature of the tools of this class is a large number of shocks and a high number of revolutions. Perhaps the market for such perforations is presented in the market. Moreover, in this segment there are tools of foreign and Russian production. An example of such a device can be called the punch of the Russian production of Baikale 113a. This is one of the easiest and most low-power tools. The power of its engine is only 550 watts, the impact force of 1.8 Joule with a weight of only 2.5 kilograms. Its power and blow strength is enough to drill a hole in the concrete with a diameter of up to 20 millimeters. This model has only two modes - it is a simple drilling and drilling with a blow.
2. Heavy - more than 8 kilograms and more than 1500 watts. Equipped with SDS-MAX cartridges. They allow you to use borants up to 60 millimeters. This class basically includes professional tools. With the help of them, you can make holes with a diameter of up to 50 millimeters when using a solid bora. If you use hollow crowns, you can get holes up to 130 millimeters in diameter.
3. Average - from 5 to 8 kilograms and a capacity of 700-1500 watts. In these models there may be both types of cartridges. The impact force in the tools of this class is up to 8 Joule. They can make a hole in concrete, consider irregularities on the concrete surface. Some models can even be destroyed with a metal grid. SDS-TOP-type cartridges are rarely used. For the drills of 16-25 mm, they are enough.

Knowing the rules for separating tools into classes, you can more confidently understand the question, how to choose a good perforator. An affiliation of the model to one or another class can be found, for example, by laying the engine. If this is a light class machine, the engine is located horizontally, and the machines of the two other classes are vertical layout.

Many perforators can work both from the network and from the battery. Moreover, a battery-operating tool is usually more expensive. Sometimes it is simply not justified to overpay for such devices, because their mobility is not particularly needed when working.

Much more important than the presence of electronic adjustment of rotation, which today is equipped with many modern perforator models. This feature will allow you to select the optimal speed of rotation necessary for work, depending on the following parameters:

1. Burue size.
2. Current load.
3. Material and other.

This has a positive effect on the end of the work. In addition, this feature will allow to extend the life of the instrument.

For household needs, the model of the middle class is quite enough. Heavy perforators are more for professional use.

Additional features

These functions are designed to expand tools.

1. Reversive mode. It makes it possible to get a tool in case of jamming and use it also as a screwdriver. This greatly facilitates the work of the user with the perforator.
2. Soft start. Some tools immediately after switching on is randomly heated. The "soft start" function allows you to avoid it. On such perforations there is a stopper of the switch, thanks to which it will not be necessary to constantly press the start button.
3. Safety clutch. This feature removes the engine from overheating and breakage.
4. Anti-vibration system. This system is mainly equipped with expensive tool models. In such models, there is also a completely insulated housing of the monolithic metal, a two-speed gearbox. When working with them there is a smaller level of noise.

Tool value

The following characteristics affect the price of perforators:

1. Power.
2. The number of embedded functions.
3. Number of components.

The most cheap perforators are tools in the price framework 80-100 dollars. Middle class models cost from 250 to 350 dollars.

Professional perforators with three work modes will cost at least 1000 dollars.

What to choose the perforator to the home master

1. For use in everyday life, you do not need a very powerful and heavy tool. Therefore, the most optimal option will be the models of the middle class. For example, Makita perforators.
2. For professional use, it is best to take a high-performance tool equipped with many modern functions that were discussed above. Bosch perforators are considered one of the best professional tools.
3. For household and professional use, the sets of drills should be included in the tool package.
4. If you wondered how to choose the perforator correctly, then, first of all, you need to focus on your needs. It makes no sense to buy expensive models for simple home repair work. The best perforator is the one who copes well with the tasks set in front of him.
