A perforator is a necessary thing in the household. Especially if the walls of the house are made of concrete or brick. It is not an easy task to punch these materials with an ordinary drill, even equipped with a percussion mechanism. And if you dismantle a piece of the wall if necessary, it will not work at all without a perforator. But what kind of punch to buy for the house - light or heavy, household or professional? The answer to this question in our new material.
In order to navigate the variety of these tools, let us consider their classification. This will help you choose a punch with the desired characteristics.
However, there are only a few classes - only three:
This characteristic, also called the impact energy, is measured in joules and is decisive for such devices. After all, it depends on how deep the drill is able to immerse into the material. For lightweight drills of household type, this value does not exceed 1 - 2 Joules. Keep in mind that with a low impact energy, you cannot punch holes properly. After all, the puncher will work like a hammer drill.
There are also three systems for attaching a drill to the device. They affect the behavior of the device during use, as well as its reliability.
The system - SDS plus - is used in small punchers (up to four kilograms in weight). Such a device can make holes with a diameter of not more than three centimeters. It is convenient and compact, so it is used in everyday life most often they are equipped with household models.
Moreover, for this type of mounting of a drill, a snap can be purchased, as they say at every corner, unlike a snap for a rarer SDS max system, which in some small stores can be not to meet.
This indicator is not fundamental. Even the best punch for the house has lower power than any drill. After all, the energy when punching holes goes much less than when they are drilled. The drill of the perforator should not turn as fast as the drill on the drill. And to achieve a high speed of rotation you need a lot of energy. Lightweight drills, ranging from 400 to 800 watts, are well suited for home repairs. They can be called the most popular.
The number of these modes is again three. There are perforators with one mode of operation, and with two or three modes.
When choosing a particular model, carefully study the instructions. It indicates how many modes a particular device has. After all, any model may have differences precisely in this parameter.
In my opinion, the availability of 3 operating modes is optimal.
The perforator can be either a straight shape or bent at a right angle in the shape of the Latin letter "L".
In the corner models, the engine is positioned vertically, and its cooling by reducing the length is more intense.
Because of these design features, the continuous operation time of this type of device is longer than that of direct-shaped models. And they lead the resource. However, corner drills are not without drawbacks, which are solid weight and dimensions.
Therefore, to wield such a perforator is often less convenient than a direct form device.
To easily cope with stubborn concrete, rapidly punching walls with a diameter of 1.6 to 2.0 cm, we need a device with the following parameters: >
Even glancing at the punchers in the store, you can often immediately see where the household tools are and where the professional tools are. After all, they are for convenience painted by manufacturers in two different colors. Determining which one is better to buy a punch for the house (that is, household) look at the brands listed below. This is MAKITA, BOSCH, Hitachi, STERN. And now about each of the manufacturers will tell more.
Household punchers of the Japanese company Makita are light, comfortable and reliable devices. If you want to make a small repair in the office or at home, hang up shelves, make recesses for wiring, then Makita will perfectly fulfill all the tasks. The switch mode (from normal drilling to drilling in shock mode) for these devices is located behind. There is also a reverse handle.
The most popular models for use in everyday life are: Makita HR2450 (it’s him in the photo), Makita HR2470 and Makita HR2470FT.
Bosch German rotary hammers, made using the most modern technologies, are distinguished by increased reliability and high quality. Their clearly working electronics, time-tested, practically does not fail. It provides the most accurate adjustment of the rotational speed of the drill. If you see the tool of this brand blue in the store, then know that this punch is intended for professional craftsmen.
For those who are looking for a device to use at home, you need to pay attention to the models painted in green. What kind of specific models I will not advise, they are quite a lot and the quality of them all at the proper level.
These perforators come from Japan. If you just have to perform work on making holes for fasteners, then pay attention to the low-power lightweight model Hitachi DH22PG. It has two modes, light as a feather, and copes with the bulk of everyday tasks. In principle, and some professional work of this "kid" on the shoulder. After all, it develops a good torque, overcoming the most solid obstacles.
With it, you will not get tired - extremely comfortable handles and light weight will not allow it.
These are his characteristics:
This is an Austrian brand. Reliable and solid, but suitable only for those who are confident in their abilities. After all, it produces perforators very weighty. These are both professional and household models, the power of which varies from 620 to 1250 W. Stern's company does not like excesses, its perforators are distinguished by severity and minimalism. They have a button to turn on, drowning that, you can work for a long time, as well as a mode switch (there are three of them in this model) and that's it. No more parts on the case are provided.
However, sometimes there is a frequency regulator on the case.
