If it is preferable to equip the hands of a professional builder with a specialized tool, then in solving everyday problems the universal device will be the best option. But this rule does not always apply - for example, in the case of screwdrivers, the ability of the device to adapt to different needs is highly appreciated by specialists. In working with hardware, no special approaches to the workflow are required, therefore, wide functionality is only beneficial. These features are endowed with the Bosch PSR Select, which has a 12-bit drum at its disposal. The user of this tool can quickly change functional elements without stopping the workflow. But not only this is noteworthy a screwdriver model from German developers.
Tool Overview
In working with screws, many are faced with problems of the lack of the necessary screwdriver with the appropriate size. Using the wrong tool can disrupt the hardware structure, as a result of which the removal of the element will become much more complicated. It is generally accepted that a screwdriver is the best way to solve such problems. This is so, but its effectiveness is determined not by power supply, but by the possibilities of working with a wide range of heads. Bosch developers drew attention to this aspect. The PSR Select cordless screwdriver is capable of screwing up to 90 screws, the diameter of which does not exceed 0.5 cm. Usually, high functionality affects other operating parameters, but in this case, the creators managed to preserve both the compact size of the tool and the optimal power, which is enough to perform simple operations with standard screws.
Specifications
Externally, the tool resembles a simple model of a screwdriver, designed for domestic needs. However, Bosch PSR Select offers users a lot of branded options, analogues of which are rarely found in devices from competing manufacturers. Provides this functionality with a balanced filling, the technical parameters of which are presented below:
- The torque when working with soft materials is 3.5 Nm.
- The frequency of rotation when unscrewing solid-state screws 4.5 Nm.
- The idling frequency of the device is 210 rpm.
- Cartridge - represented by a magnetic drum for bits.
- The number of nozzles is 12.
- The mass of the tool is 0.5 kg.
- The maximum diameter of the screws is 0.5 cm.
- The battery voltage is 3.6 V.
- Charge replenishment time - 4 hours.
Features of the device
This model cannot be attributed to typical devices. The creators deviated from the common rules for the design of screwdrivers in several directions at once. The main feature of the modification is its ability to work with a large number of screws. There are many offers on the market that are also focused on the ability to work with dozens of hardware. But in this case, the keyless chuck is effective not only due to the ability to service various self-tapping screws, but also due to its ease of use. The user can change the nozzles almost without delay, and the spindle lock allows him to comfortably perform manual tightening if necessary. The device also stands out by electronic technology. In particular, the company has provided indicator elements for monitoring the operating parameters of the device and a backlight that allows operations without a flashlight in the dark or in hard-to-reach places.
Power tool
The introduction of lithium-ion technology in the construction industry has been observed for a long time. Manufacturers with varying degrees of success are developing cordless modifications to their conventional power tools. In some cases, the end user praises the provided autonomy, and in others it criticizes the creators for the increased dimensions and inconvenience of the case. In part, the disadvantages of such models can also be attributed to the Bosch PSR Select Li Ion-on, whose battery cell, of course, makes the design heavier. But on the other hand, it is in screwdrivers that a small mass additive can play a positive role, exerting additional force on the working element.
As for other aspects of the implementation of the lithium-ion unit, it is spared from two common shortcomings. This applies to self-discharge and the so-called memory effect. That is, the tool, even with a long idle time, remains fully operational. To control the battery condition allows a special backlight on the device. The rest of the technology justifies itself. For example, a battery voltage of 3.6 V almost smoothes the performance advantages of power screwdrivers . High power potential for such a tool is not required, which cannot be said about the advantages of battery life.
Accessories & Supplies
The manufacturer develops special screwdriver bits for the screwdriver, through which the owner will be able to provide effective work with screws in different conditions. Bosch produces both multi-element kits and single pieces, depending on the material characteristics. In particular, kits for 7, 10 and 31 bits are available to users. Also, the keyless chuck can be equipped with special bits with a titanium-nitridium coating. These are high-strength elements that will help to cope with branded carbide screws. In addition, the manufacturer complements the set with socket wrenches for screws with an external hexagon.
Positive reviews
Both specialists and home masters speak favorably about the model. High ergonomics of the instrument are noted, which provides convenience for the user himself and significantly saves time for complex operations. Many mention the benefits of backlighting. Although, this is an elementary option that is present even in budget models. Of course, most owners emphasize the advantages of the bit holder, which is supplied with this screwdriver. The reviews indicate that during operation the tool allows you to quickly change the nozzle and with high accuracy to carry out work operations.
Negative reviews
Some screwdriver owners find backlash and gaps on the case. Such flaws are visible not with the naked eye, but there is no question of serious deformations. The device leaves much more negative impressions due to the lack of a power regulator. Although the performance is quite enough for confident work with plastic and wood, the lack of speed modes significantly limits the functionality that the screwdriver was originally provided with. Reviews say that the adjustment of the force is simply necessary for the full tightening of the screws. Just this tool does not provide this opportunity, so the final screwing must be done with your own hands with a separate screwdriver. There is also a criticism of bits, which notes the absence or weakness of magnetization, which also causes inconvenience.
How much does a Bosch PSR Select cost?
The model does not look cheap and is quite expensive for its class. If we compare the quantity and quality of functions with the price tag, then the benefit will most likely not be in favor of the tool. In the Russian market, a German screwdriver in this modification is available on average for 3.5-4 thousand rubles. Again, for devices of this purpose, the amount is quite decent and you can purchase a professional model for it. But if we consider the Bosch PSR Select as a device with a hint of revolution, then everything falls into place. Still, there are not so many exact analogues on the market, and the combination of good performance, a capacious battery and almost a unique bit holder makes the model very attractive even for 4 thousand.
Conclusion
The technologies embodied in this screwdriver individually have long been used by many well-known manufacturers. However, the implementation of the battery pack and drum with bits stands out in this version. On the other hand, the Bosch PSR Select screwdriver has some pretty serious flaws. Having provided sufficient effort, the developers of the tool could not develop this direction to the modern level. For an average model in the price segment today, it is impossible to imagine the lack of speed adjustment. Also, the device sins with some flaws in terms of the characteristics of the snap. By and large, this development is useful as a universal tool for working with screws in the domestic environment.
