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

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

Design and purpose of the tool

Unlike hand-held 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 comes in handy in cases where you need to make a hole in a dense material (concrete, brick).

If we say in a simplified way what an impact drill is, it will look like this: it is a regular drill with a hammer drill function. But this option should be considered as an additional option, not a primary one. It will not be possible to constantly use the device to work with concrete and brick - otherwise it will quickly wear out.

In addition, the device is used for the following tasks:

• cutting threads 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 convenient tool that is suitable for solving various problems. The device consists of several elements:

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

Rotation is carried out due to the operation of an electric motor. It transmits the impulse to the cartridge through a gearbox. When starting, 2 ratchets begin to work, they repel each other, due to which the impact mechanism works. These elements wear out quite quickly, 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 sphere and at home. 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 W. If the model has 2 speeds, it will be at least 700 W. Power is selected depending on what the impact drill is needed for. If for domestic purposes models with a parameter in the range of 700-800 W are suitable, then for professional purposes a larger reserve 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 provides more powerful torque. This device can be used to work with screws and ring cuts.
3. We can say about the impact drill that it is a powerful tool with the additional function of a hammer drill. Modern models are equipped with various buttons, including a speed switch and a speed controller. There is also a special button that turns on the kick function. The more options you can adjust, the easier it is to operate the device.
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 remove the screw and wedge the drill.
5. No less useful is the overload protection option. Its presence helps you 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 understand how an impact drill works and pick it up. If the tool fits well and has a rubberized handle, it will be comfortable to work with.
7. The type of chuck fixation can be quick-release or toothed. If you plan 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 it with a margin of 4 m.

You can describe an impact drill, what it is a device for drilling and an additional impact option. If you also choose taking into account the brand, it is recommended to pay attention to models from Makita, Bosch, Interskol, Hitachi and others. Before purchasing, you should study reviews on different portals and 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, during work 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 equipment into the chuck and check that it is firmly fixed.
3. Inspect the wall, make sure that there are no hidden wiring or fittings installed in it.
4. To understand how to use an impact drill, you need to hold the tool in 2 hands. During operation, hold it firmly to prevent it from slipping.
5. You need to press the drill, but not too hard - otherwise it will jam. You should work especially carefully if additional attachments are used.
6. The purpose of the impact drill is also associated with the reverse stroke. It is turned on only after the engine has completely stopped.
7. Be sure to wear safety glasses when drilling.
8. After completion, the instrument is held in the hands until it comes to a complete stop. 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.

Electric 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 glasses, hold the tool firmly in your hands, and follow safety precautions.

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

The impact drill, the characteristics of which are described in the article, is a universal tool. It can be used to drill holes in metal and wood products and work in hammer drilling mode.In part, it can even replace a hammer drill, which saves time and money.
