The list of basic operations for machining materials includes drilling. With the help of special equipment, the master forms holes with certain parameters, which in the future can perform different functions. Moreover, measures of this kind are carried out both on individual elements of building materials and on finished structures. In particular, drilling a hole in a partition can be carried out in order to lay communication routes. Depending on the characteristics of the material being processed, appropriate equipment is used.

Description of drilling machining

Most often this operation is cutting the material, which results in the formation of a cylindrical hole. But there are other sections - it depends on the tool used. In determining the parameters of the resulting hole, two main characteristics are taken into account - depth and diameter. In accordance with the required indicators, equipment with a cutting head of a suitable size is also selected. As for the tool itself, with which you can drill a hole, it is represented by a wide range of devices and units with differentcharacteristics. The most popular are electric drills, which can also be used in working with solid materials. The main thing is to choose the appropriate nozzle. For soft building materials, the use of manual mechanical drills is sufficient.

Drilling holes in metal

For the processing of metal parts, electric machines are usually used, which are supplied with carbon steel drills. Before work, it is very important to properly mark future holes. This is usually done with a core. This device, even on hard surfaces, allows you to form a conical recess, which will become the basis for "drilling". In order not to spoil the workpiece, it is advisable to drill holes in metal only with heads that have cutting edges. The presence of the latter depends on the quality of the drill sharpening. The fact is that the angle of the cone can be different and is determined by the hardness of the material for which it is intended. The harder the metal grade, the larger this angle should be, for example, steel is usually sharpened by 120 degrees.

Drilling wood

Wood is one of the most malleable materials in processing, which led to a wide variety of tools that allow you to perform this kind of drilling. The simplest way to implement this procedure is to use a gimlet, but it is only suitable for forming small diameter holes. Basically, a drill is used. It is enough to use a mechanical device in which the drill is attached. Despite the soft structure of the material, drilling holes in wood requires great care. It is necessary to strictly maintain the verticality of the working element and at the same time exert moderate pressure. The quality of such operations depends largely on the position of the master. In the process of radial drilling of cylindrical wood products, the drill can “take away”. It is possible to prevent such phenomena with the help of a conductor, which will provide the necessary balance of the position of the functional element.

Drilling holes in the wall

This task is the most difficult, because the materials of construction of the walls are hard and rigid. The most effective tool for such tasks is a diamond drill, but in some cases you can get by with an electric drill. The most important thing is to choose the right device according to performance characteristics. The power of the device should be at least 600 W, and the frequency should be up to 2500 rpm. The greatest difficulty can be caused by drilling large holes for laying ventilation ducts. The diameter of such a channel can be 18-20 cm. A carbide drill with a diameter of at least 12 mm will help create such a hole. That is, the formation of the hole of the required size will have to be performed by a whole series of approaches. To begin with, it is necessary to designate the contours of the future channel, after which, with small indents, make holes along them. At the final stage, it will be possible to carefully landunnecessary fragment.

Technical nuances in the drilling process

Mechanical operations entail severe overheating of the working elements. The negative consequences of such processes can be reflected both in the form of damage to the processed material and in the deformation of the drill. Coolants and lubricants should be used to prevent overheating. For a mechanical tool, ordinary water will be enough, and if you plan to drill a hole using a powerful electric machine, then you should prepare a special emulsion. In addition, working with walls can be accompanied by the abundant formation of concrete dust. In order to exclude contamination of the entire site, it will not be superfluous to initially provide for the possibility of supplying a power tool with a special vacuum cleaner, which will collect garbage during the operation.

Conclusion

Technological development of building tools today allows us to perform a wide range of machining activities, including drilling, with high quality. Moreover, not only equipment is being improved, but also cutting elements. Improvement of high-strength carbide tips allows you to cope with both metal and brick. Moreover, it is possible to drill holes of this type without the involvement of specialists. True, it is still necessary to know the basics of operating a power tool and, in general, the features of the technological process. For their part, manufacturers of drilling equipment are also striving to meet the needs of the general consumer. As a result, along withBy increasing the technical and operational parameters, such a tool acquires ergonomic handles, security systems and protection against the same overheating.
