The competition between mains and cordless tools remains relevant today, when both directions have advanced quite well in terms of technological development. A power tool running on a wall outlet is becoming more compact and lightweight, and self-powered models expand the range of tasks available to perform. In the modern design, the cordless jigsaw allows you to use the negative factor in the form of increasing the mass of the tool as a virtue. The weighty case in this case plays the role of a stabilizer and contributes to the accurate execution of cutting. However, the prolonged 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, such saws are almost identical to electrical devices. The differences include the ability to continuously process the material without a network. Typically, the autonomous operation of the tool allows you to perform cutting operations within a few hours. As for the materials available for sawing, the cordless jigsaw in the basic versions successfully copes with wood, plastic and gypsum panels. Increasingly, models appear that can cut metal sheets, including steel. Structurally, such devices have a peculiarity in the form of integration of the battery pack and connecting channels for chip removal. The latest versions are equipped with lithium-ion devices that allow you to use a jigsaw without recharging up to 8 hours.
Varieties of cordless jigsaws
Specialists traditionally divide models of this type into classes. In turn, each class involves 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 battery jigsaw, which suggests the possibility of power from both the built-in battery and the mains. But such devices have a significant drawback. Of course, they can be used in almost any environment, but the implementation of two energy supply systems as such significantly increased the stuffing 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 operations with cutting metal pipes. Household appliances, on the contrary, have a small power reserve and are oriented to work with wood-based materials.
Bosch Jigsaws
Under the brand of a German manufacturer, technological, productive and functional jigsaws are produced. True, they are not cheap - an average of 8 to 12 thousand rubles. A professional line with blue models demonstrates advanced developments. Among them, one can note the possibility of adjusting the rotation speed, several modes of the pendulum stroke and the presence of indicators with operating indicators. Bosch household cordless jigsaw also has many features, but, of course, is of a different kind. First of all, these are ergonomic qualities, which are expressed in the form of a convenient mushroom handle, backlight, etc. In expensive models, a laser pointer also appears, which allows you to more accurately perform cutting in a given direction. German jigsaws also have structural features - this applies to the cast sole device, durable aluminum support and chip evacuation systems.
Bosch GST model reviews
One of the most popular representatives of the family of cordless jigsaws of a German company. Users praise the cutting apparatus for the quality processing of any materials available for such purposes. Ergonomic advantages are also noted - this applies to the small mass, compact size and the presence of security systems. There is a drawback. The fact is that the Bosch GST cordless jigsaw lacks a blowing system. Users working with large amounts of wood materials emphasize that within a few minutes after the start of cutting, the intended cut line becomes invisible due to sawdust. True, the blow function is present in some advanced modifications of the GST series. In addition, the owners testify to the effective operation of the LED backlight.
Jigsaws Makita
While the Bosch developers focused on achieving high performance indicators and introducing new technologies, the Japanese company focused on improving the familiar constructional qualities and security systems. As a result, Makita cordless jigsaws received the function of protection against accidental starting, an advanced cooling system and a dust extraction pipe, which precisely ensures chip removal during operation. As for the control capabilities, the user can adjust the sawing intensity using a special toggle switch. As in German jigsaws, models of this brand suggest the ability to adjust the pendulum stroke with the selection of the optimal power load.
Makita JV100DZ reviews
According to users, the model is convenient, quite functional, saves energy and is reliable. However, the owners have to pay relatively low power for these qualities. The fact is that the JV100DZ modification, although in many respects reminiscent of the development of GST, its technical stuffing is implemented at a lower level. A low class of the tool is also confirmed by a budget price tag of 5 thousand. On the other hand, the Makita cordless jigsaw evokes a lot of pleasant comments from ordinary home craftsmen who use the device for domestic needs. For example, in the cutting of sheet aluminum, wood up to 65 mm thick and plastic, this model performs well.
Jigsaws from other manufacturers
There are also models of cordless jigsaws from Ryobi, AEG, Spec, Enkor, etc. on the market. In most cases, the products of these brands are inexpensive, but in practice the operation also does not cause much enthusiasm. Basically, these are average devices in terms of performance, devoid of advanced functions. Of course, in each line you can find a relatively technological model, but options in the spirit of a laser pointer and LED backlight are still better developed with premium battery jigsaws. Reviews of Hitachi models, for example, mark the successful execution of a rare technology for replacing a file without the use of an auxiliary tool.
Conclusion
Oddly enough, the developers of cordless jigsaws pay more attention to improving the design and optional capabilities of the tool, rather than improving the autonomy. The only exceptions are the Bosch and Hitachi brands. The German company, in particular, sold a cordless jigsaw, in which the power supply can maintain a charge for a long time while in storage. That is, the user will not need to replenish the battery energy supply each time before using the tool. As for Hitachi, the designers of this brand released a whole line of Slider batteries, which are lightweight and have a long working life.
