In the household, it is often necessary to carry out minor and more thorough repairs, which forces the prudent owner to purchase various kinds of tools. Modern repair units are capable of solving several problems at the same time. This is the case with drills: these devices will be able not only to drill holes, but also to perform the function of a screwdriver, to ensure a uniform consistency of various kinds of solutions.
The correct drill is also important for professionals: in this case, the device should not have great versatility, but the function assigned to it must perform at a decent level for a long time.
The main criterion that determines which model is better to buy is the potential purpose of the tool.
Domestic use requires a device to be versatile and multifunctional. It cannot be mercilessly exploited for hours on end. Often, a home assistant is used from time to time: when it is necessary to hang a shelf on the wall, assemble a cabinet or mix a small amount of building mixture for redecorating the interior. Therefore, it is important that the device, in addition to drilling holes, can tighten and unscrew the screws, play the role of a mixer, and break through the partition.
However, the latter should not be overused, since a constant shock load can lead to backlash in the spindle, reducing the accuracy of the basic drilling procedure. If you do not remember that a drill is not a substitute for a hammer drill, you can significantly reduce its service life. Since the home appliances are intended for ordinary users, it is important that an adequate level of protection and limited power ratings are provided. When purchasing a device, it is better to give preference to a set with accessories placed in a case. This provides savings (since purchasing the necessary components can be more expensive), ease of use and storage.
Professional tools are used daily and for a considerable period of time. If the device is capable of providing high-quality continuous operation for an hour or more, then this option is acceptable for a builder of a certain orientation (some representatives of this kind of construction equipment can work for 7-8 hours in a row). At the same time, the scope of application of such a professional unit is not as wide as that of a household counterpart. For such models, the set of functions is often limited, with a higher cost. In general, such devices are distinguished by their ergonomics and a decent level of implementation of specific tasks.

An amateur hammer drill is a compact, lightweight device with a sufficient power level of 0.5 kW. It is characterized by the presence of reverse movement (R), regulation of the rotation speed (E).
Using this tool, you can solve simple everyday tasks: drill small holes in concrete (up to 10 mm in diameter), wood (up to 25 mm), metal (up to 8 mm); use as a screwdriver and mixer.
The double-jaw keyless chuck makes cutting tool changes quick and easy. However, according to user reviews, the fact of using such a chuck over time creates conditions under which it is difficult to center the drill: the drilling process may not be entirely accurate despite the fact that the shaft is perfectly centered. In general, this is a common problem with self-locking chucks.

In the rating of quality brands for the production of construction tools, one of the leading positions is occupied by Bosch, whose popular models were considered in this article.
Bosch drills cannot be attributed to budget models, however, the demand for the product does not disappear. The cheaper green devices are for home use, while the more expensive blue ones are for professionals. Prices for them are 3-4 times higher than for an amateur product. The reason for this difference is the increased performance of blue structures: they must ensure long-term operation, not overheat, the body must be characterized by increased tightness, the handles must be comfortable to grip, it is important to use increased strength steel for the manufacture of key assemblies. These nuances determine the price difference.
An important point is that a professional instrument is more highly specialized, while amateur models are multifunctional.
By organizing the correct operation and maintenance of the tool, you can operate any structure for a long time, solving everyday work tasks or specific household needs.
