How to choose a perforator for homework? Choice by performance - Setafi

There are several ways to choose a hammer drill for domestic purposes. First of all, you need to take into account the power of the tool, which is directly related to its weight. Also pay attention to the force of impact, the number of revolutions of the spindle. The main selection recommendations are described in the article.

Types of punchers

There are several types of devices, and the classification is carried out according to several parameters. The main criterion is the weight of the tool:

1. Lungs weigh less than 4 kg and develop power in the range of 400-800 watts. If we consider which puncher to choose for the home, then you can stop on these models. They are used for drilling holes in concrete for mounting dowels, socket boxes, junction boxes. You can also hang the ceiling, install a profile for mounting a plasterboard wall.

2. Medium - weight within 8 kg, while the power is up to 1000 watts. Such devices are used for the installation of communication systems, in electrical types of work. They are indispensable for finishing, chasing walls, making through holes for pipes and removing old floor coverings.
3. If we consider which puncher to choose for professional purposes, you can pay attention to the “heavy” group. It combines devices weighing 8-10 kg or more with a power of about 1500-2000 watts. With their help, materials are removed, communications are laid, and major repairs are carried out.

Another classification is related to the location of the engine. It can be positioned vertically and horizontally. In the first case, the design is compact, which makes it possible to work even in hard-to-reach places. Horizontal arrangement is more common in household appliances. It is this puncher for the home that is bought most often.

Another way to choose a hammer drill for homework is related to the type of percussion mechanism. Previously, electromechanical models were common, which involve the application of great effort. But today they are practically not produced.

Therefore, both for home and professional purposes, electro-pneumatic tools are chosen. They provide a hit of great force, even if the power is low.

Main technical parameters

If you think about how to choose a hammer drill for your home, you need to take into account several technical parameters. The most important is power, although there are other indicators that you should also pay attention to.

Power

The devices develop different power, the range is quite wide - from 400 to 2000 watts. At the same time, 400-600 watts is quite enough in the domestic sphere. Sometimes such models are used by professional workers. For example, they are suitable for mounting a suspended structure. The tools are convenient because they are quite light in weight, you can work with them for a long time.

Energy and frequency of impacts

The choice of a perforator must also be carried out according to the impact energy. It can be 1-20 J, sometimes more. This criterion affects which materials can be pierced. For example, to work with concrete, stone, reinforced concrete surfaces, powerful devices are needed. But they are dangerous when making holes in foam concrete and brick. It is important to understand that the impact force cannot be adjusted, it is associated only with such a parameter as the power of the perforator.

The frequency is the number of movements made by the striker per unit of time. The parameter can be in a wide range up to 5000 beats per minute. At the same time, the frequency of the drill is even higher, but the puncher has a greater impact force.

Spindle speed

Another important parameter by which you can choose a perforator for your home. If you use the device only to drill holes, a rotation speed of 2000 rpm is sufficient. If you use it for drilling, high speed is not required. For most devices for professional use, the spindle rotates up to 1000 per minute, which is quite enough.

Operating modes

The choice of a hammer drill for the home is also associated with the number of operating modes. There are models with 2 and 3 modes. In the first case, they can work for drilling, as well as for drilling with impacts. In the second, the “hit” mode is added. Such models are used more widely, since they can also be used for dismantling and removing the coating. It is better to purchase them - "with a margin."

Maximum drilling diameter

The diameter can also be in a wide range - from 10-160 mm. Moreover, if drilling is carried out with a crown, then the indicator does not exceed 80 mm. If the tool is used only for holes for anchors, dowels, it is enough to purchase just such a model. If it is needed to make holes for different types of communications, junction boxes, the diameter should exceed 100 mm.

Cartridge type

Regardless of the features of the device (vertical or horizontal), 2 types of cartridges are used:

1. SDS-plus - they are installed in light devices up to 4 kg. The shank has a diameter of 10 mm.
2. SDS-max - installed in medium and heavy class models. They have a weight of 4 kg, while the diameter of the shank in this case is 10 mm.

Weight

On the one hand, I want to choose a puncher with less weight, so that my hands do not get so tired during work. But do not think that this is the right model. In fact, mass is directly related to power. If the tool is required only for drilling small holes for dowels, it will weigh no more than 4 kg. But more versatile models of the middle class with a weight in the range of 4-8 kg.

There are different types of perforator, they differ in technical characteristics. For home purposes, light and medium models with a power of up to 1000 watts are quite suitable. If you choose a device for professional work, it is better to consider more powerful devices up to 2000 W and weighing more than 8 kg.
