Drill-screwdriver Bosch GSR 1440-LI: features, specifications, user manual, reviews

The quality of fixing the fastening material depends not only on the characteristics of the part itself. To a considerable extent, the way the connection is implemented also affects the strength of the future design. One of the most effective approaches to performing such operations is the use of a screwdriver. Modern models offer a lot of opportunities for twisting, and the multifunctional tool also allows drilling surfaces. Such screwdrivers include the modification of the Bosch GSR 1440-LI Professional, the capacity of which is enough to work with loose construction materials.

General information about the model

Screwdriver represents the middle segment of a professional tool designed for drilling and working with hardware. If you do not take into account operations with solid construction materials, then the model can be considered as universal. The creators provided the GSR 1440-LI with an ergonomic grip, wide functionality and a powerful engine. True, these characteristics are relevant only in the context of this segment and against the backdrop of low-cost models. The screwdriver still comes from a household tool and is not able to perform complex operations on drilling concrete and especially thick metal. But the function of the drill shows itself well in the processing of wood materials, soft plastics and thin metal sheets. The same surfaces are suitable for the implementation of screw locking capabilities.

Specifications

If you strictly limit the scope of this tool, the basic parameters will be optimal. Actually, the GSR 1440-LI Professional modification is similar in class to the performance level of the power fill, but the performance is slightly out of the total. The technical characteristics presented below confirm this:

• The diameter of the drilling of wood is 25 mm.
• The depth of drilling metal - 10 mm.
• Battery voltage is 14.4 V.
• The battery capacity is 1.5 Ah.
• The twisting moment - 30 Nanometers.
• The number of revolutions per minute is up to 1400.
• The number of stages of the intensity of rotation is 25.
• The size of the cartridge is 10 mm in diameter.
• The number of speed modes is 2.
• The diameter of the screw suitable for screwing is a maximum of 7 mm.
• Weight - 1,3.

Structural and power capabilities allow the device to be used both in domestic repair operations and in some professional construction activities. At the same time, it is important to take into account one flaw, which is rarely sinned by full-fledged drills designed for professional use. The fact is that the model Bosch GSR 1440-LI is deprived of the possibility of impact, which limits its use in working with walls.

Technological features

The model is different from the battery tool segment . This is a rather popular niche, since models of this type allow you to perform work actions without being tied to the mains. But even in this category, the developers were able to allocate their product due to lithium-ion batteries powerful at 14.4 V. Moreover, if necessary, the GSR 1440-LI battery screwdriver can be equipped with elements with a voltage of 10.8 V with a capacity of up to 3 A * h . The ECP system also belongs to the features of the model, thanks to which the user can count on stable performance of the battery function, as it is protected from overheating, overloads and premature discharges. Implemented in the apparatus and the possibility of a series of twists. The presence of a brake makes it possible to produce several manipulations with different hardware without interruptions and delays.

Accessories for Bosch GSR 1440-LI

The basic configuration of the screwdriver includes 2 Li-Ion batteries, a quick charger and a suitcase. The working equipment will have to be purchased separately. The manufacturer recommends that the instrument be equipped with branded bits from the manufacturers "Metabo", "Stayer" and "Expert". The parts are supplied both in sets of universal purpose, and individually - single bits, as a rule, are oriented to perform specialized operations. Also, sets of accessories are distributed, in which there are bits and drills of different sizes. In addition, the GSR 1440-LI drill-screwdriver can be supplemented with dust extractors and chip collectors. On the quality of drilling such equipment will not affect, and the place after work will remain clean. However, an instrument of this type, unlike perforators, leaves behind a small amount of dirt.

User's manual

In the process of performing work operations, it is recommended to use only a suitable tool for technical characteristics - this refers to bits and drills. Also before work it is desirable to scan structures for the presence of electrical wiring and other communication lines. If the tool jammed during drilling, it is necessary to turn off the engine. In such situations, it is also necessary to prepare for reactionary attacks, which will cause a reverse move. As the manufacturer notes, the GSR 1440-LI can cause a short-time reverse stroke when doing screwing and unscrewing the hardware. Therefore, it is necessary to hold the tool tightly, controlling its function. The same applies to handling blanks. If it does not have its own fastening, it is necessary to provide either an additional clamping device or securely hold the material in its hands. When working with small workpieces, the use of a vice for fixing is still the best option. This fastening is useful both in terms of operator safety, and in terms of ensuring a quality result.

Screwdriver maintenance GSR 1440-LI

After carrying out work activities, the tool must be cleaned of dust and chips. Also during drilling it is recommended to provide free ventilation through structural slots. Periodically, the body of the device should be inspected for any gaps in the joints, since the vibrating effect can increase their dimensions. The battery deserves special attention. Since the Bosch GSR 1440-LI Professional is powered by a lithium-ion battery, it is necessary to protect the element from mechanical influences, direct sunlight and moisture. The fact is that such batteries without reliable sealing in the case are environmentally harmful.

Positive feedback about the model

The model evokes good impressions on the totality of ergonomic qualities. In many respects they are conditioned by the very concept of a battery tool. The manufacturer has implemented a reliable and effective interaction of the battery and power fill, which is noted by many users of the GSR 1440-LI. The reviews, in particular, underscore the possibility of long-term operation without a network, stable maintenance of the claimed capacity and at the same time a small weight of the model. Also, experienced builders praise the function of the regulator of turns, coupled with a large number of operating modes. This allows you to precisely select the parameters of the force specifically for the maintenance of a particular piece of hardware. This can be added and serial twisting, which reduces the time for the workflow.

Negative feedback

A rare case for the German manufacturer "Bosch", when the number of critical reviews about his tool exceeds the number and significance of the merits. First of all, the owners complain about the lack of backlighting. This disadvantage seems strange to many, since a cordless screwdriver is initially calculated on the possibility of working in remote and inaccessible places, in which, incidentally, there may be no lighting. But the biggest disadvantage of this drill is the flimsy design. The presence of backlashes and gaps is found in the first days of operation. In addition, the modification of the GSR 1440-LI is provided with a weak cartridge holder. At the same time, the quick-clamping locking system itself has been successfully implemented and really greatly improved the ergonomics of the model. However, unsatisfactory indicators of the strength of this mechanism in many doubt. At least, users do not recommend using this modification to perform responsible repair and installation operations.

Conclusion

Almost every modern model of the Bosch construction tool has one or several characteristics that distinguish the product from the total mass of analogues. In this case, the device turned out to be quite average in terms of technical and operational qualities, albeit with a successful power system. To the strengths, which do not deprive the screwdriver GSR 1440-LI, you can relate the versatility and ergonomics. In particular, the model shows itself quite well when working with typical simple tasks. The impression spoils the unfinished structural design and the absence of some functions, including illumination. But already in the basic set provides a convenient and roomy case. By the way, to reconcile with the shortcomings of the screwdriver helps and low cost of 7 thousand rubles. Professional models of a higher level from the same Bosch line are estimated at 10 thousand and above. Another thing is that in the families of competitors there are many affordable offers of the same segment that are distinguished by high-quality assembly and high performance.
