In the household, it often becomes necessary to carry out minor and more thorough repairs, which forces the zealous owner to acquire various kinds of tools. Modern repair units are capable of solving several tasks at the same time. This is the case with drills: these devices can not only drill holes, but also perform the function of a screwdriver, ensure a uniform consistency of various kinds of solutions.
The right drill is also important for professionals: in this case, the device should not have great versatility, but the function assigned to it must be performed 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 the appliance to be versatile and multifunctional. It cannot be mercilessly exploited for hours on end. Often, a home assistant is used on a case-by-case basis: when it is necessary to hang a shelf on the wall, assemble a cabinet, or mix the building mixture in small volumes when redecorating the interior. Therefore, it is important that the device, in addition to drilling holes, can tighten and unscrew screws, play the role of a mixer, and break through a partition.
However, the latter should not be abused, since a constant shock load can lead to spindle backlash, reducing the accuracy of the basic drilling procedure. If you do not remember that the drill is not a substitute for a hammer drill, you can significantly reduce its service life. Since household units are intended for ordinary users, it is important that an adequate level of protection and limited power ratings be provided. When purchasing a device, it is better to give preference to a set with accessories placed in a case. This provides savings (since the purchase of the necessary components can be more expensive), ease of use and storage.
Professional tools are used daily and for a significant 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 construction master of a certain direction (some representatives of this kind of construction equipment can work for 7-8 hours in a row).At the same time, the scope 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, a higher cost is typical. In general, such devices are distinguished by ergonomics and a decent level of implementation of specific tasks.
Representatives of blue color are intended for professionals. This row in the marking has the initial letter G, the designation of subsequent letters is denoted by: SB - shock, DB - unstressed; SR - screwdriver.

The amateur impact drill is a compact, lightweight device with a sufficient power level of 0.5 kW. The presence of a reverse movement (R), rotation speed adjustment (E) is characteristic.
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 two-jaw keyless chuck makes changing the cutting tool quick and easy. However, according to user reviews, the fact of using such a cartridge over time creates conditions under which it is difficult to center the drill: in this case, 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.
The maximum rotation speed is 3000 rpm at a stroke rate of 48000 beats/min. Switching between impact and non-impact modes is possible thanks to the switch on the top of the case. The dust extraction option makes it possible to connect a vacuum cleaner.The average price is 2450 rubles.
In the ranking 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, but the demand for the product does not disappear. The cheaper green devices are for home use, while the more expensive blue models are an option for professionals. Their prices 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 distinguished by increased tightness, the handles must be comfortable to grip, and it is important to use high-strength steels for the manufacture of key components. Such nuances are due to the price difference.
An important point is that a professional tool is more highly specialized, while amateur models are multifunctional.
By organizing the correct operation and care of the tool, it is possible to operate any design for a long time, solving everyday work tasks or specific household needs.
