Impact drill: what is the tool for and how to use it? – Setafi

Impact drills, unlike conventional drills, can work in hammer drilling mode. This allows them to be used for making holes in concrete and brick. Therefore, if you briefly answer the question of what an impact drill is for, we can say that this is a tool with the additional function of a hammer drill. A more detailed answer can be found in this article.

Device and purpose of the tool

Unlike manual models, an impact drill is a more versatile device. It performs not only the main task associated with drilling, but also an additional function - impact. It is useful in cases where you need to make a hole in a dense material (concrete, brick).

To put it simply, what an impact drill is, it will turn out like this: it is a regular drill with a hammer drill function. But this option should be considered as an additional one, not the main one. It will not work to constantly use the device for working with concrete and brick - otherwise it will wear out quickly.

Along with this, the device is used for such tasks:

• threading in a metal surface;
• twisting and unscrewing the fastener;
• drilling work in various surfaces, including metal and stone.

We can say that an impact drill is a handy tool that is suitable for solving various tasks. The device consists of several elements:

• Electrical engine;
• reducer;
• frame;
• bearings;
• start button;
• speed controller;
• cartridge.

Rotation is carried out due to the operation of the electric motor. It transmits momentum to the chuck via a gearbox. When starting, 2 ratchets begin to work, they mutually repel each other, due to which the percussion mechanism works. These elements are quickly erased, so it is not recommended to work in this mode too often.

How to choose the right tool

Today, different types of instruments are produced, including unstressed ones. But a drill with an impact mechanism is suitable for different jobs, which is why it is often used both in the professional field and in everyday life. To choose the right model, it is recommended to consider several factors:

1. First of all, engine power is very important. The indicator can be in the range of 400-1500 watts. If the model has 2 speeds, it will be at least 700 watts. The power is chosen depending on what you need an impact drill for. If for domestic purposes models with a parameter in the range of 700-800 W are suitable, then for professional ones a larger margin is required up to 1000-1500 W.
2. Each tool has a gearbox. But it comes in different types - with one or two speeds. The second option is better because it gives more powerful torque. Such a device can be used to work with a screw and an annular cut.
3. We can say about the impact drill that it is a powerful tool with the additional function of a rotary hammer. Modern models are equipped with various buttons, including a speed switch and a speed control. There is also a dedicated button that turns on the kick function. The more options you can adjust, the easier it is to operate the instrument.
4. It is useful to understand what an impact drill means. It has a mechanism that makes holes in concrete and brick. Moreover, many models are equipped with additional functions - reverse (that is, reverse rotation). It helps to pull out the screw and wedge the drill.
5. Equally useful is the overload protection option. Its presence helps to understand how to choose an impact drill. If the drill jams during operation, the motor will automatically stop. This will save both the motor itself and the gearbox.
6. When choosing, you need to figure out how the impact drill works, pick it up. If the tool lies well and it has a rubberized handle, it will be comfortable to work.
7. Chuck locking type - can be quick-clamping or toothed. If it is supposed to work for a long time, it is better to choose the first option, because it allows you to quickly replace the mechanism. In the second case, you will have to use a special key.
8. Finally, pay attention to the length of the cable. At first glance, 2 m is enough, but it is better to take with a margin - 4 m.

You can describe an impact drill, what it is a drilling device and an additional impact option. If you also choose taking into account the brand, it is recommended to pay attention to the models Makita, Bosch, Interskol, Hitachi and others. Before buying, you should study the reviews on different portals, evaluate the pros and cons of each option.

How to use the tool

The impact drill, the photo of which is presented below, is slightly different from a conventional device. Therefore, while working, you need to take into account several features:

1. For the first time after purchase, make sure that the cable is intact and complete.
2. Install the tool in the chuck, check that it is firmly fixed.
3. Examine the wall, make sure that no hidden wiring or fittings are installed in it.
4. To understand how to use an impact drill, you need to take the tool in 2 hands. During operation, firmly hold it, preventing slipping.
5. You need to press the drill, but not too hard - otherwise it will jam. Particular care should be taken if additional nozzles are used.
6. The purpose of the impact drill is also associated with reverse (reverse). It is turned on only after the engine has completely stopped.
7. Be sure to use protective goggles when drilling.
8. After completion, the tool is held in the hands until it stops. If you understand why you need an impact drill, it will be easier to follow safety precautions. Even when the spindle stops working, you should not touch it - you can get burned.

Impact drills are quite easy to use. They are equipped with comfortable handles that should be held with 2 hands. When choosing a suitable model, first of all, pay attention to the power of the impact drill. If for household tools you can choose devices up to 700 W, then for professional purposes - at least 800 W. When using a drill, it is important to wear goggles, hold the tool firmly in your hands and follow safety precautions.

As a rule, the service warranty is 1-2 years. But if you use the tool correctly, the life of the electric drill will be much longer. To do this, you need to regularly clean, replace drills, and do not exert too much effort during work.

The impact drill, the characteristics of which are described in the article, belongs to universal tools. It can drill holes in metal and wood products, work in the drilling mode with impact. In part, it can even replace a puncher, which saves time and money.
