The arsenal of tools of any responsible owner should include the presence of a drill and a screwdriver. The only question is what characteristics such assistants should have. Today, multipurpose devices are common in which both functions are organically combined. The Bosch PSR 1080 LI universal screwdriver just belongs to such models, allowing you to solve repair and installation problems at home. Of course, there is no question of the shock function and the ability to cope with concrete, but this machine can conveniently screw a hardware or drill a board without undue effort on the part of the operator.
Tool Overview
In choosing any tool, a lot depends on the range of tasks that will be assigned to it. German designers produced an apparatus designed to perform simple operations, but with comfort and high quality. In general, the model has an average level of technical and operational indicators, which are endowed with almost all cordless household screwdrivers. Instrument prices range from 3.5 to 4 thousand rubles. This is not bad for the basic version of a power drill, given the level of the manufacturer.
The model is equipped with a quick-clamping chuck, a body with a rubberized handle and wide settings for operating parameters. It should be noted that these and other features became the basis for the development of the next generation of the family. Modification Bosch PSR 1080 LI 2 retained the best qualities of its predecessor, but at the same time provides the user with a wider choice of speeds and has a backlight function.
Specifications
The power filling is powered by a 10.8 V battery, which is a good indicator for home models. For comparison, professional devices of this type have a capacity of 14 V or more. Of course, their scope is much wider. In this case, the engine allows you to process only wood and thin metal. Working with the first material allows the use of working elements with a diameter of 20 mm, and metal workpieces lend themselves to drills by 6 mm. Without recharging, the filling of the Bosch PSR 1080 LI can function for 3 hours, according to the manufacturer. In practice, a more modest indicator is noted - almost up to an hour. But the tool provides an opportunity to configure the operating mode. Torque, for example, has 11 steps - from soft rotation of 9 Nm to an intense stroke of 20 Nm.
Screwdriver Features
Models from the class of household devices rarely pamper the owners with something outstanding and do not always get even those functions that are common in the professional segment. The only exceptions are technologies aimed at improving ease of use. Actually, in this direction the Bosch PSR 1080 LI screwdriver developed. The charger, for example, performs its function without removing the battery. That is, the user does not have to perform unnecessary manipulations with the extraction of the supply unit.
Also, the model is distinguished by the presence of a charge indicator, which is represented by an electronic device. By the same principle, a speed controller is also implemented, due to which the accuracy of processing a material with specific characteristics is increased. Special attention deserves the Auto-Lock system. In essence, this is an analogue of the common clamps for cartridges, however, in the development of Bosch the replacement of this part is easier and faster. Thanks to this system, one could count on an almost uninterrupted workflow. But this, unfortunately, is prevented by the battery that is supplied with the Bosch PSR 1080 LI screwdriver. The charger, despite the ergonomics in physical use, replenishes the battery's potential in 3 hours. Therefore, you can not count on long and continuous operation sessions.
User's manual
The use of a drill / driver is recommended only in combination with suitable format and high-quality work items. The same applies to the use of chargers - in order to maximize the battery life, only Bosch accessories should be used. Before you begin, you must adjust the Bosch PSR 1080 LI. Instructions for use indicate the possibility of adjusting the torque through a special switch. Thus, it is possible to establish the optimal stroke for working with one or another material. In the process, it is important not to overload the tool, as well as to ensure reliable fixation of the workpiece. After the operation is completed, clean the screwdriver, check the integrity of its structural parts and remove the bit or drill from the cartridge.
Positive feedback on the model Bosch PSR 1080 LI
Most of the users of this model are non-professionals who need to have a drill and a screwdriver in the farm for universal use. Therefore, there are no particular complaints about power and performance in general. Bosch PSR 1080 LI handles screwing up hardware in furniture and creating holes in wooden or plastic cladding. The main advantages of a German screwdriver are ease of use. The shape of the handle and the presence of indicators with a stroke regulator, as well as the design of a quick-clamping chuck, work on ergonomics.
Negative reviews
If there are no complaints about the performance of a screwdriver, then the battery power supply system leaves many users with not the best impressions. Again, the design of the non-removable power supply is a plus, but its operating time leaves much to be desired. In intensive use mode, according to many users, the Bosch PSR 1080 LI engine remains operational for 1-2 hours. The situation is aggravated by the fact that the time to recharge the battery exceeds this time period. If you plan to purchase a device for one-time improvements with the creation of one or two holes, then this nuance will be insignificant. But regular use of the tool does not combine with long interruptions in the process of work activities.
Conclusion
The screwdriver segment is oversaturated with offers of functional and at the same time powerful devices. But not all of them are able to provide durability and reliability during operation. Especially such qualities are rarely characterized by cordless screwdrivers, the prices of which are in the range of 3 thousand rubles. In turn, the Bosch company offers an ergonomic model with a strong assembly, which can be purchased for the same money. True, making a choice in favor of a German product, one should prepare for some of its shortcomings. The main one is the short operating time and the duration of the recharge in the battery.
