What is the difference between a drill and a perforator? The main differences between the tools - Setafi

There are several parameters by which it is easy to understand how a drill differs from a hammer drill. All of them are related to the purpose of each tool. If the first device is used primarily for drilling, then the second is equipped with a percussion mechanism. This allows it to be used for crushing holes even in very dense materials.

Impact mechanism

The differences between a drill and a hammer drill are primarily related to the mechanism that provides the percussion function, that is, to the percussion mechanism. Quite a few drill models have this option. It allows not only drilling, but also making holes in dense materials, for example, in the thickness of concrete or brick. It helps to hang a shelf, install a cornice.

However, the tool does not have a percussion mechanism as such. The shock is obtained due to the fact that the gears rotate rapidly, touch each other through the teeth and bounce during operation. It is this rebound that is called a blow.

Moreover, it turns out not too strong, that is, the pressure on the material increases, but not to the same extent. In addition, the hands during the application of the impact mode get tired quite quickly. This is due to the fact that in order to strike it is necessary to press the apparatus with its own weight. It turns out that if you choose a drill or a hammer drill specifically for the impact function, you should stop at the second option.

Moreover: the main purpose of the perforator is the crushing of solid material. In any models, even with not too much power, there is a percussion mechanism. And thanks to this, it is possible to obtain a hole of even a significant diameter, without applying much effort and without leaning on the whole body. This is the main criterion by which it is easy to determine how an impact drill differs from a hammer drill.

Power

Power is one of the most important indicators by which any device is chosen from screwdrivers to concrete mixers. The tools in question are no exception. The difference between an impact drill and a hammer drill is directly related to the main purpose of each device. Since the first device has less power and is not equipped with an impact mechanism, its performance is lower. The second indicator is somewhat less, since this is quite enough.

Moreover, it is not entirely objective to judge what is better - a drill or a hammer drill, only in terms of power, because:

1. Both devices often have approximately the same figure. So, the most productive drills give up to 2000 watts. These are percussion instruments, as well as mixers capable of mixing cement mortar.
2. Not always the more power, the better. So, with the same value for crushing dense materials, you definitely need to choose a perforator. The fact is that, as already mentioned, it is equipped with an impact mechanism, while drilling machines do not. But for most everyday tasks, high performance is not needed.
3. Powerful devices are several times more expensive than models for home use. At the same time, it is not advisable to overpay money for "extra" watts.

Thus, it is necessary to correctly understand what is the difference between a drill and a hammer drill. These are similar tools that can even partially replace each other. But the main purpose is different - it is this factor that must be taken into account when choosing.

Processed material

This item is also closely related to the purpose of the devices. The difference between a hammer drill and an impact drill is that the first machine can work even with the densest materials:

• concrete;
• natural stone;
• brick.

As for the drilling machine, it is mainly designed to work with such materials:

• tree;
• stone;
• metal;
• ceramics;
• glass.

It can also be used for brick and concrete. But even in this case, it is clear what is the difference between an impact drill and a hammer drill. The latter is used to work with dense materials. It is used for crushing and drilling, obtaining various holes, including large diameters.

Nozzle selection

The difference between a drill and a hammer drill is quite clear in the example that the nozzles show. In the case of a drilling machine, manufacturers often sell tools without nozzles as such or immediately supplement them with a small set. They include drills of different diameters and shapes, they differ depending on the material being processed:

• metal;
• tree;
• concrete.

Moreover, concrete drills have an additional reinforced impact part. It also plays a role in the formation of holes in a brick or concrete wall.

If we talk about the difference between a hammer drill and an impact drill, it is easy to see that the first device has a different tooling:

1. Drills, a set of drills for drilling in different modes (impact, unimpact).
2. Crowns that allow you to make holes in the wall. Looking at them, you can also notice the difference between a drill and a hammer drill. With the help of the latter apparatus, it is possible to obtain holes of any type - deaf ones are used for mounting sockets, and through ones are used for installing communications, for example, pipes.

In addition, the perforator equipment is characterized by different types of shank - SDS maximum or plus. Depending on the technology of operation, they can be used in a "dry" mode or using a water cooling system. Therefore, we can simplistically say that a hammer drill is a drill, moreover, a more highly specialized one, since the main purpose is associated with the percussion function.

Lifetime

Another indicator that determines the difference between a hammer drill and a drill is related to the service life. It is widely believed that the first tool is more reliable, since it is designed for professional tasks.

In fact, the period depends on various factors - primarily on the build quality, brand awareness, intensity of use (how often), as well as on the accuracy and experience of the master himself. In this sense, there is no difference between a hammer drill and an impact drill.

Typically, manufacturers indicate that the period of trouble-free operation is 3-5 years, declaring 1-2 years as a warranty period. But if you handle it carefully, lubricate it in time, the tool can work longer - up to 10-15 years, and sometimes up to 20 years.

Therefore, if you need to decide what to choose - a drill or a hammer drill, you should focus mainly on what tasks you need the device for. It is perfectly acceptable to buy a tool for home use. If you use it not too often and properly maintain it, it will work properly even longer than a professional device.

Thus, do not confuse an electric drill with a hammer drill. The instruments are similar in appearance and even in device. But they are equipped with different mechanisms and solve different problems. Most often, a drill is optimally suited for domestic purposes. A perforator for rare work can also be rented.
