The segment of the processing hand tool is notso long ago expanded due to electric jig saws. A compact tool with a thin saw blade allows both professional carpenters and home craftsmen to perform a neat cut in wood, plastic and metal workpieces, leaving the minimum amount of waste. German jig saw Bosch occupies one of the leading positions in this niche, demonstrating the reliability and high quality of the result.
The manufacturer produces functional,ergonomic and practical in the maintenance of jig saws, which also differ in the optimized assembly and longevity of the element base. For example, for the professional segment, the developers offer devices provided with an in-system locking system for SDS files, which saves time for tooling changes without losing to alternative fasteners in the reliability index.
As for functionality, the electricThe Bosch jig saw is equipped with a pendulum stroke option, a chip blowing system and support for high power rotations. Such provision is especially useful in furniture production, since it allows carpenters to use the tool for a long time with the maximum load of the engine. In the domestic conditions of use, the highlight of the jig saw, the laser pointer and the smooth start are appreciated. The owner of the model with such functionality, even without special training, will be able to perform qualitatively even a complex figured cut.
Basic classification of German jigsaw modelsinvolves the separation of household and professional apparatus. Accordingly, it is a tool with a blue and green casing. Household devices are characterized by a limited power resource, a small set of options and a modest bundle. However, saw blades for the Bosch jigsaw of the amateur class quite correspond to the quality of professional-level consumables. For production and construction, more productive units are offered, capable of running smoothly up to 8 hours. The quality of the element base is also higher, so you can count on long-term operation without repair operations.
Also, the Bosch jigsaw family can be divided intonetwork and battery models. The first work from the outlet, and the latter, as a rule, are supplied with lithium-ion batteries. The presence of a battery makes it possible to use the instrument at remote sites without a central power supply. What's more, the Bosch battery-powered jigsaw does not lose power to its network counterparts. The manufacturer strives to optimize the power fill, offering universal in use devices.
The assortment covers practically the entire spectrumtechnical and operational parameters, characteristic of modern jigsaws. The main working characteristic is the power potential. For the operation of this tool, in principle, no high power is required, so on average this figure varies from 500 to 1000 W. Unless individual industrial models are provided with engines for 1200-1500 watts. For domestic needs, enough fret saws Bosch PST 900, whose power is 620 watts. No less important and the parameters of processing blanks. Models for home use provide a stable cutting of wooden parts with a thickness of about 70-80 mm and steel products up to 3-5 mm. Professional versions are able to confidently handle 135 mm preforms made of wood and aluminum up to 20 mm thick. Also it is necessary to take into account the division of models by phase. Household devices are connected to the network by 220 W, and industrial ones to 380 W outlets.
An entry-level solution with an average cost2,5-3 thousand rubles. The device has a power of 500 watts and saws wood up to 65 mm thick. As for metal blanks, this model can only soft products up to 10 mm. The peculiarities of the development include increased ergonomics, which has always been famous for household electric tools of this brand. In particular, the Bosch PST 650 jigsaw has got a proprietary anti-vibration Low Vibration, thanks to which the hands of the wizard do not get tired even during long working sessions.
Reviews of this version mark its reliability,a small mass, maneuverability and a convenient mechanism for changing saw blades. But there are also negative impressions. For example, many point to the rapid wear of the Bosch jigsaw brushes in this version. In general, the tool is recommended for making straight simple cuts, but not for figured cutting.
One of the cheapest representativesa professional class of German jigsaws. The model is available in the domestic market for 6.5-7 thousand rubles. Against the background of similar proposals from competitors, this is a decent price tag, but, again, the costs are justified by the high quality of the assembly and the element base.
The device is provided with moderate powerthe engine at 600 W, does not set records in the segment for processing possibilities of workpieces (cutting depth of 23 mm for wood and 20 mm for metal), but it is advantageous for its wide functionality. In particular, reviews about the Bosch GST 850 BE jigsaw emphasize the presence of a four-step pendulum stroke, a dust extraction system, a speed regulator and a smooth start. At the same time, there is a clear cut without defects at the edges, which is very important for low-power devices. With regard to shortcomings, the unstable sole of a structure is often mentioned, which has to be further controlled during operation.
This model can be regarded asA universal apparatus for a small workshop or a household. Capacities of 620 W are enough to work with wood, metal, rubber and ceramic products. In this case, the configuration of the cut may be different. With due skill, the craftsman will be able to perform not only a flat longitudinal cut, but also a cutout with a support for a 45-degree angle. Especially for accurate processing, a Cut Control system is provided, which facilitates control over the cutting line.
Users also note the advantageModel as an optimal tool for cutting soft-billets without distortion. If we talk about the weak points of the Bosch 900 PEL jigsaw from the PST series, first of all the owners emphasize the unsuccessful realization of the flashlight, which illuminates the indicated line of cutting. In addition, when working at high speeds, the locking lever may interfere.
Very successful implementation of cordless jigsawhousehold class, although the cost of the model exceeds this level - 6 thousand rubles. The voltage of the Li-lon feeder is 18 V, and the maximum cutting depth is 80 mm in wood. Steel plates cut with a thickness of up to 10 mm. The model has incorporated a lot of typical functions, like a dust extraction and lighting, but even this is not the main thing in this device. The Bosch PST 18 LI cordless jig saw has a number of brand technologies that distinguish it from the general segment. It is enough to note the electronic module for speed control and the built-in Syneon Chip system, which increases the running time on one battery charge. As a result, users put autonomy jigsaw on the first place in the list of benefits, also noting its high performance and ergonomics.
The manufacturer clearly segments the cutting blades for the intended purpose, as well as the fabrication materials. So, the following types of saws are distinguished:
According to the material of manufacture can be distinguished clothsof carbon steel, bimetallic carvers and saws from high-speed alloy, which are recommended for use in working with non-ferrous metals and plastics. The average dimensional range along the length of the webs varies from 65 to 135 mm.
To the construction tools of Bosch, asrule, those who are interested in high quality of processing of materials address. And it's not always employees of large-scale production, woodworking factories and metal warehouses. A solid tool with reliable parts and safe electrical stuffing may well come in handy to an ordinary home master. In particular, the low-power Bosch jigsaw allows you to perform accurate cutting of wooden floor coverings, while preserving the protective and decorative layers outside the processing area. Apparatuses of medium and high power are useful as universal assistants.
Do not forget that the jigsawwheels do not workonly with wood, but also with metal. In the garage, for example, this tool will perform a delicate cutting of damaged parts of the body. Another thing is that the quality of cutting will also be influenced by the artist's experience. Therefore, experts in carpentry recommend that beginners before cutting a blank make several trial cuts on waste material with a similar structure.
