Competition between corded and cordless tools remains relevant today, when both directions are quite advanced in terms of technological development. Plug-in power tools are getting smaller and lighter, and self-powered models are expanding the range of tasks available. In the modern version, the cordless jigsaw allows you to use the negative factor in the form of an increase in the mass of the tool as an advantage. The weighty body in this case plays the role of a stabilizer and contributes to accurate cutting. However, long-term use of such jigsaws still gives a noticeable load on the brush, forcing manufacturers to look for ways to minimize weight.
Features of cordless jigsaws
In terms of performance and functionality, these saws are almost identical to electric machines. The differences include the ability to continuously process material without a network. As a rule, autonomous operation of the tool allows you to perform cutting operations for several hours. With regard to the materials available for sawing, the cordless jigsaw inbasic versions successfully cope with wood, plastic and gypsum panels. Increasingly, there are also models that can cut metal sheets, including steel. Structurally, such devices have a feature in the form of integration of the battery pack and connection of channels for chip removal. The latest versions are equipped with lithium-ion devices that allow you to use the jigsaw without recharging up to 8 hours.
Varieties of cordless jigsaws
Specialists traditionally divide models of this type into classes. In turn, each class assumes its own power indicators, a list of materials available for cutting, a set of functional additions, etc. It is important to note the popularity of universal models. This is a cordless jigsaw, which assumes the possibility of being powered both from the built-in battery and from the mains. But such devices have a significant drawback. They, of course, can be used in almost any conditions, but the implementation of two power supply systems as such has significantly increased the filling of the tool. Also, jigsaws of this type can be divided into professional and household. The first category is represented by high-power devices, which, for example, can be used at remote sites when performing complex metal pipe cutting operations. Household appliances, on the contrary, have a small power reserve and are focused on working with wood-shaving materials.
Bosch jigsaws
Technologicalproductive and functional jigsaws. True, they are not cheap - on average, from 8 to 12 thousand rubles. The professional line with blue models showcases cutting-edge developments. Among them, it is possible to note the possibility of adjusting the rotational speed, several modes of the pendulum stroke and the presence of indicators with performance indicators. The Bosch household cordless jigsaw also has many features, but, of course, of a different kind. First of all, these are ergonomic qualities, which are expressed in the form of a comfortable mushroom-shaped handle, lighting, etc. In expensive models, a laser pointer also appears, which allows you to more accurately cut in a given direction. There are also design features in German jigsaws - this applies to the device of a cast sole, durable aluminum support and chip removal systems.
Reviews of the Bosch GST model
One of the most popular representatives of the family of cordless jigsaws from a German company. Users praise the cutting unit for the quality processing of any materials available for such purposes. Ergonomic advantages are also noted - this applies to low weight, compact size and the presence of security systems. There is also a disadvantage. The fact is that the Bosch GST cordless jigsaw is devoid of a blowing system. Users who work with wood-based materials in large volumes emphasize that just a few minutes after the start of cutting, the intended cut line becomes invisible due to sawdust. True, the blow-off function is present in some improvedmodifications of the GST series. In addition, the owners testify to the effective operation of the LED backlight.
Makita Jigsaws
If the Bosch developers focused on achieving high performance and introducing new technologies, the Japanese company put the improvement of the usual structural qualities and security systems at the forefront. As a result, Makita cordless jigsaws received an accidental start protection function, an advanced cooling system and a dust extraction pipe, which just ensures the removal of chips during operation. As for the control options, the user can adjust the sawing intensity using a special toggle switch. As in German jigsaws, models of this brand suggest the possibility of setting the pendulum stroke with the selection of the optimal power load.
Reviews about the JV100DZ model from Makita
According to users, the model is convenient, functional enough, saves energy and is reliable. However, owners have to pay for these qualities with relatively weak power. The fact is that the JV100DZ modification, although it resembles the development of the GST in many respects, its technical stuffing is implemented at a lower level. The low class of the tool is also confirmed by the budget price tag of 5 thousand. On the other hand, the Makita cordless jigsaw causes a lot of euphonious reviews from ordinary home craftsmen who use the device for domestic needs. For example, in cutting thin sheet aluminum, woodthickness up to 65 mm and plastic, this model performs well.
Jigsaws from other manufacturers
There are also models of cordless jigsaws from Ryobi, AEG, Spets, Enkor, etc. on the market. In most cases, the products of these brands are inexpensive, but in practice, operation also does not cause much enthusiasm. Basically, these are average devices in terms of performance, devoid of advanced features. Of course, in each line you can find a relatively high-tech model, but options in the spirit of a laser pointer and LED backlight still better master premium cordless jigsaws. Reviews of Hitachi models, for example, note the successful execution of a rare saw blade replacement technology without the use of an auxiliary tool.
Conclusion
Oddly enough, the developers of cordless jigsaws pay more attention to improving the design and optional features of the tool, rather than increasing autonomy. The only exceptions are the Bosch and Hitachi brands. The German company, in particular, has implemented a cordless jigsaw, in which the power supply can retain a charge for a long time while in storage. That is, the user will not need to replenish the battery power each time before using the tool. As for Hitachi, the designers of this brand have released a whole line of Slider batteries, which are distinguished by their low weight and increased resourcework.
