The quality of fixing the fixing material depends not only on the characteristics of the part itself. To a large extent, the strength of the future design is also affected by the manner in which the joint is realized. One of the most effective approaches to performing such operations is to use a screwdriver. Modern models offer a lot of possibilities for twisting, and a multifunctional tool also allows you to drill surfaces. Such screwdrivers include the modification Bosch GSR 1440-LI Professional, the power of which is enough to work with loose building materials.
Model Overview
The screwdriver is the middle segment of a professional tool designed for drilling and working with hardware. If you do not take into account operations with solid-state building 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 background of low-cost models. The screwdriver still comes from a household tool and is not able to perform complex operations for 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 realizing screw screwing capabilities.
Specifications
If you strictly limit the scope of this tool, then the basic parameters will be optimal. Actually, in terms of the performance of the power filling, the GSR 1440-LI Professional modification is similar to the competitors in class, but the performance indicators are slightly out of the general row. The technical characteristics presented below confirm this:
- Diameter of wood drilling is 25 mm.
- Metal drilling depth - 10 mm.
- The battery cell voltage is 14.4 V.
- Battery capacity - 1.5 A * h.
- The torque is 30 Nm.
- The number of revolutions per minute is up to 1400.
- The number of stages of rotation intensity is 25.
- Cartridge size - 10 mm diameter.
- The number of speed modes - 2.
- The diameter of the screw suitable for screwing is a maximum of 7 mm.
- Mass - 1.3.
Structural and power capabilities make it possible to use the device in domestic repair operations, and in some professional construction activities. At the same time, it is important to take into account one flaw that rarely sits full-fledged drills designed for professional use. The fact is that the Bosch GSR 1440-LI model is deprived of the possibility of impact, which limits its use in working with walls.
Technological features
The model differs in belonging to the segment of the cordless tool. This is a fairly popular niche, since models of this type allow you to perform work without being tied to the mains. But even in this category, developers were able to isolate their product due to powerful lithium-ion batteries with a capacity of 14.4 V. Moreover, if necessary, the cordless screwdriver GSR 1440-LI can be equipped with elements with a voltage of 10.8 V and a capacity of up to 3 A * h . The model’s features include the ECP system, thanks to which the user can count on the stable performance of the battery function, since it is protected from overheating, overloads and premature discharges. Implemented in the apparatus and the possibility of serial execution of twists. The presence of the brake makes it possible to perform several manipulations with different hardware without interruptions and delays.
Accessories for the Bosch GSR 1440-LI
The basic set of the screwdriver includes 2 Li-Ion technology batteries, a quick-charger and a suitcase. Work equipment will have to be purchased separately. The manufacturer recommends equipping the instrument with proprietary bits from the manufacturers “Metabo”, “Stayer” and “Expert”. Parts are supplied both in universal sets and individually - single bits are usually oriented towards specialized operations. Accessory kits are also common, in which bits and drills of various sizes are present. In addition, the GSR 1440-LI drill / driver can be supplemented with dust extractors and chip collectors. Such equipment will not affect the quality of drilling, and the place after work will remain clean. However, a tool of this type, unlike perforators, leaves behind small amounts of dirt.
User's manual
In the process of performing work steps, it is recommended to use only equipment that is suitable for technical specifications - this applies to bits and drills. Also, before work, it is desirable to scan structures for the presence of electrical wiring and other communication lines in them. If the tool gets stuck during drilling, turn off the engine. In such situations, one should also prepare for reactionary shocks, which will cause a reverse stroke. According to the manufacturer, the GSR 1440-LI can cause a short reverse course when performing twisting and twisting hardware. Therefore, you should hold the instrument firmly in control of its function. The same applies to handling the workpiece. If it does not have its own fastening, it is necessary to provide either an additional clamping device, or hold the material securely in your hands. When working with small workpieces, the best option is to use a vise for fixing. Such fastening is useful both in terms of operator safety and in terms of ensuring a high-quality result.
GSR 1440-LI Screwdriver Maintenance
After completing work steps, the tool should be cleaned of dust and chips. Also, during drilling, it is recommended to provide free ventilation through structural slots. Periodically check the casing of the device for gaps at the joints, since the vibration effect can increase their size. The battery also deserves special attention. Since Bosch GSR 1440-LI Professional is powered by a lithium-ion battery, it is necessary to protect the cell from mechanical stress, 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 makes a good impression on the totality of ergonomic qualities. They are largely due to the very concept of a cordless tool. The manufacturer has implemented reliable and effective interaction between the battery and power filling, which is noted by many users of the GSR 1440-LI. The reviews, in particular, emphasize the possibility of long-term operation without a network, stable maintenance of the declared power and, at the same time, low weight of the model. Also experienced builders praise the function of the speed controller, coupled with a large number of operating modes. This allows you to precisely select the force parameters specifically for the maintenance of a particular hardware. Serial twisting can be added to this, which reduces the time spent on the work process.
Negative reviews
A rare case for the German manufacturer Bosch, when the number of critical reviews against his tool exceeds the number and significance of advantages. First of all, the owners complain about the lack of backlight. This drawback seems strange to many, since the cordless screwdriver was initially designed to work in remote and inaccessible places where, by the way, there may be no lighting. But the biggest drawback of this drill is its flimsy design. The presence of backlashes and gaps, many find in the first days of operation. In addition, the GSR 1440-LI is equipped with a weak cartridge holder. At the same time, the quick clamping system itself was rather successfully implemented and really significantly increased the ergonomics of the model. However, unsatisfactory indicators of the strength of this mechanism are doubtful for many. At least, users do not recommend using this modification to perform critical repair and installation operations.
Conclusion
Almost every modern model of the Bosch construction tool has one or more characteristics that distinguish the product from the total mass of analogues. In this case, the device turned out to be quite average in technical and operational qualities, although with a successful power system. The strengths that the GSR 1440-LI screwdriver is not deprived of include versatility and ergonomics. In particular, the model performs well when working with typical simple tasks. The impression is spoiled by the unfinished structural basis and the lack of some functions, including backlighting. But on the other hand, a convenient and roomy case is already provided in the basic kit. By the way, the low cost of 7 thousand rubles helps to reconcile with the shortcomings of a screwdriver. 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 in the same segment that differ in high-quality assembly and high performance.
