The list of basic machining operations for materials includes drilling. Using special equipment, the master forms holes with certain parameters, which in the future can perform different functions. Moreover, events 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 done to lay communication paths. Depending on the characteristics of the material being processed, appropriate equipment is used.
Description of drilling machining
Most often, this operation is a cutting of material, as a result of which a cylindrical hole is formed. 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 perform hole drilling, it is represented by a wide range of devices and assemblies with different characteristics. The most popular are electric drills, which can be used in working with solid-state 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, electrical apparatuses are usually used, which are equipped with carbon steel drills. Before working, it is very important to correctly mark the 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 the metal only with heads that have cutting edges. The presence of the latter depends on the quality of the sharpening of the drill. The fact is that the cone angle 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, for steel sharpening is usually performed at 120 degrees.
Wood drilling
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 holes of small diameter. Basically, a drill is used. It is enough to use a mechanical device in which the drill is mounted. Despite the soft structure of the material, drilling holes in a tree requires great accuracy. It is necessary to strictly maintain the verticality of the working element and at the same time to exert moderate pressure. The quality of such operations depends largely on the position of the wizard. In the process of radial drilling of cylindrical wooden products, the drill can "lead". Such phenomena can be prevented 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, since the materials of the wall construction are distinguished by hardness and rigidity. The most effective tool for such tasks is a hammer drill with a diamond crown, but in some cases you can get by with an electric drill. The most important thing is to choose the right device for performance. The power of the device should be at least 600 watts, and the frequency - up to 2500 rpm. The greatest difficulties can cause drilling large openings for laying ventilation ducts. The diameter of such a channel can be 18-20 cm. A carbide drill, the diameter of which is at least 12 mm, will help to create such a hole. That is, the formation of the right-sized hole will have to be performed by a whole series of approaches. To begin with, you should outline the contours of the future channel, after which, with small indents, make holes on them. At the final stage, it will be possible to carefully drop off an unnecessary fragment.
Technical nuances during the drilling process
Mechanical operations entail severe overheating of the working elements. The negative consequences of such processes can be reflected in the form of damage to the processed material, and in the deformation of the drill. To prevent overheating, coolants and lubricants should be used. For a mechanical tool, ordinary water will be enough, and if you plan to drill a hole using a powerful electric device, you should prepare a special emulsion. In addition, work with walls can be accompanied by abundant formation of concrete dust. To exclude pollution of the entire site, it will not be out of place to initially provide for the possibility of supplying the power tool with a special vacuum cleaner that will collect garbage during the operation.
Conclusion
The technological development of the construction tool allows today to qualitatively carry out a wide range of machining measures, including drilling. Moreover, not only equipment is being improved, but also cutting elements. Improving high-strength carbide tips allows you to cope with both metal and brick. Moreover, it is possible to drill holes of this type without connecting specialists. True, the basics of the operation of a power tool and, in general, the features of the process are still necessary. For their part, manufacturers of drilling equipment also seek to meet the ordinary consumer. As a result, along with increasing technical and operational parameters, such a tool acquires ergonomic handles, safety systems and protection against the same overheating.
