A drill is a tool with which you can make holes in various materials. These tools can be pneumatically or hydraulically driven, the latest models are more often used in restoration work in factories, when it is necessary to do a large number of drilling operations. Such tools require the installation of a hydroelectric power station, and therefore are rarely used in a domestic environment.

general characteristics

These devices can be used for industrial purposes, but they are also used in everyday life. Such devices are connected to the compressor, which is connected to a 220 volt network. They can be used to punch holes in a variety of materials. The drill in such designs is driven by an air motor, and the design of the drill itself consists of the following main parts:

• rotor on bearings;
• drive;
• cylindrical body.

The principle of operation is based on the fact that air enters the channel between the blades and the plates expand, which capture the drill fastening element and activate it. Currently, there are three types of pneumatic drills:

• pistol type - the most common device;
• straight - designed for making holes with a small diameter and is easy to use;
• corner - has a special design that allows you to use in hard-to-reach places.

All these models can be equipped with a reverse or without it.

Benefits and cons

If you use these devices in everyday life, then it is important to know that they do not have special advantages over conventional electric drills, but additional costs will also be required to purchase a compressor with which you can operate the device. In industrial production, such tools are quite in demand for the following reasons:

• does not need to be connected to electricity;
• safety;
• reliability;
• can be used in places with high gas content;
• low noise level.

There are also disadvantages:

• you need to buy a compressor;
• work can only be done outdoors or in a workshop.

Angle drill

This type of equipment is intended for professional use and is used for twisting or unscrewing self-tapping screws, making holes in hard-to-reach places, etc. The chuck of such a tool is located at an angle of 90 degrees to the rest of the body. Usually, the devices are used in specialized enterprises or industries, as well as in furniture manufacturing workshops.

Among the most popular models are the following:

• Jonnesway JAD-6249;
• FUBAG DL2600.

They remain quite reliable and have heavy-duty housings, as well as a steel gear case, which protects the tool from external negative influences. The chucks are tightened with a wrench, which makes it possible to make holes in sufficiently hard materials or narrow places. The drive key is easy to press and your fingers do not get tired during operation.

The advantages of these products include:

• light weight;
• rotation speed - 1800 rpm;
• long service life;
• it is possible to adjust the rotational speed of the drill using a valve on the body;
• small size;
• convenience of work

Relative disadvantages include the high cost of the tool and the need for a key to install the drill. Also, this tool must be operated with two hands.

Features of choice

Before buying this device, you need to determine the optimal power of the device, as well as the speed of rotation of the drill in the chuck. Currently, a fairly large assortment of these products from different manufacturers is presented on the market, the power of which can range from 500 to 1500 watts.

At the same time, it should be noted that more expensive tools have ample opportunities, and therefore if it is necessary to do constantly large amounts of work, then preference should be given to them. Such drills are able to work continuously for 9-10 hours and can withstand heavy loads, as well as wear less. Among the most popular manufacturers of these devices are:

• Hitachi;
• Makita.

Depending on the features of the use of the drill, it is also necessary to pay attention to its functionality. If the tool is intended for a professional furniture assembler, it is recommended to buy screwdriver drills, and installers need to purchase impact drills.

Home tool

If you need to buy these devices for use in everyday life, you should remember that the more functions the device has, the more it costs. If you need to do basic work, you can buy an inexpensive model. Such a tool can work continuously for 3-4 hours, which is enough to complete various tasks. You also need to remember that the power of such devices is low, but it is quite enough for homework. When choosing, it is recommended to pay attention to the following manufacturers:

• Bosch;
• Interskol.

Special functions and parameters of pneumatic drills

Some models may have a reverse, which is considered a fairly convenient function. Using such a drill, you can unscrew the self-tapping screws. Also, certain tools have an adjustable chuck rotation speed, which makes it possible to conveniently use them to perform certain jobs. If there is no adjustment of the rotational speed of the drill on the body, then it will be quite difficult to drill accurate holes with it. When working with the device, you need to firmly fix the workpieces, periodically clean and lubricate the drills and do not use them to make holes in especially strong materials.

Conventional pneumatic drills can operate on compressed air with a pressure of at least 6 atmospheres . In this case, the optimal torque for the tool is provided, and for smooth operation it is necessary to purchase the appropriate compressor and hose for connecting the tool. Also, when choosing, you need to pay attention to the fact that the manufacturer often indicates an overestimated power of his tool, and therefore it must be taken into account that in reality it can be 10-20% lower than indicated on the package.

In order not to be mistaken with the choice, it is necessary to approach the process responsibly, and it is better to invite a specialist who is well versed in this matter. In order for the instrument to work longer, it is also necessary to purchase a special unit for air preparation, which includes a filter, which allows cleaning the composition of small particles that can damage the instrument. Based on the foregoing, everyone will be able to choose the drill that is optimal for themselves and give preference to one or another model, depending on the conditions of its use. Also, everyone will independently determine the cost of the product that suits him. With the right choice and use, the tool can be used for many years.
