The presence of an angle grinder in the household makes it easy to solve the problems of processing solid-state surfaces in the repair process. In addition, this equipment, also known as a “grinder,” may be needed in locksmith events, as well as when removing unwanted raids. Today there are many models of angle grinders from different manufacturers, but the choice is recommended to make in favor of reputable companies. These include the Bosch GWS 850 CE Professional, which comes in a wide configuration, is characterized by build quality and reliability. Despite positioning as a professional unit, the grinder is quite suitable for private needs. The tool is not difficult to handle, but a set of useful options and high performance will not be superfluous. However, this model should not be overestimated either, as competing grinders also have something to offer.
Model Overview
The device is presented in the line of professional equipment, which is designed for a wide range of operations. In particular, the Bosch GWS 850 CE angle grinder handles the processing of metal materials, stone and wood. The operator will be able to perform cutting, grinding, painting, and also remove traces of paintwork and rust. High power helps the instrument to perform the listed actions qualitatively. However, this does not affect the dimensions and ergonomics of the device. The user will be able to easily manage all the capabilities of the unit without outside assistance - of course, basic training and knowledge of the features of handling the grinder will still be required.
In addition to compactness and maneuverability, the device will please the owner with electronic filling. Actually, the introduction of control systems with a hint of intelligence has long been practiced by other manufacturers, but in Bosch GWS 850 CE angle grinder this concept is implemented most successfully and without serious errors.
Specifications
Not only advanced electronic systems, but also the basic technical potential speak of the accessory of this unit to professional models. So, the German grinder has the following characteristics:
- The power potential is 850 watts.
- The number of revolutions - a range from 2 800 to 11 000 with the possibility of adjustment.
- The size of the grinding wheel in diameter is 12.5 cm.
- Grinding spindle thread - M14.
- The length of the spindle thread is 2.2 cm.
- The mass of the device in full is 2.6 kg.
- The mass of one tool is 1.6 kg.
The main thing that the tool pays attention to is a high level of power and an extensive speed range. Thanks to these characteristics, the Bosch GWS 850 CE grinder demonstrates its effectiveness even when working with stone surfaces.
Features and benefits of the model
The user controls the instrument using an electronic settings system. Compared with the adjustment in traditional models, this innovation allows you to set the machine optimal parameters for working with a specific material. In addition, the Bosch GWS 850 CE is equipped with a soft starter. This means that a sharp start of processing is excluded, as a result of which the largest number of errors are made. The user of this grinder will start work quietly, slowly and accurately. To ensure stable processing in the future, the device is also equipped with a current limiter, which will eliminate the negative effects of voltage drops.
So that the operator can easily and quickly change the components of the machine, a fixed spindle is provided in its design. Facilitates maintenance operations and the location of carbon brushes with direct access. To increase the overall structural strength, the Bosch GWS 850 CE grinder was provided with reinforced plastic and armored winding. On the one hand, protective barriers protect the user himself, on the other hand, they increase the tool wear resistance.
Maintenance
The manufacturer strongly recommends keeping the tool clean and in good condition. For this, it is necessary to use work elements that correspond to the characteristics of the material and processing conditions. It is also necessary to regularly check all slots and ventilation openings of the device, since their contamination can lead to breakage directly during the operation. In case Bosch GWS 850 CE spare parts or accessories are required, the manufacturer's service department provides original components upon request. In addition, the user can get a wiring diagram of the device - then, in accordance with it, independently determine the malfunction and eliminate it. However, without appropriate preparation, such actions are not recommended.
Operation Nuances
You can start work if several conditions are met. Firstly, the tool must be in good condition, and all its components and functional parts must be correctly selected from the point of view of the upcoming processing. Secondly, the workpiece must be securely locked. During operation, the Bosch GWS 850 CE angle grinder must not be subjected to excessive pressure. Even coarse abrasive work should be carried out with moderate tension, correctly grasping the handle of the tool. After the operation is completed, it is not necessary to turn off the machine immediately. You should leave it idling for a few minutes. This must be done, as sudden changes in voltage in the mechanical elements adversely affect the durability of the device.
Each material has its own processing characteristics. For example, in the process of cutting metal should lead the working body against rotation. This will bring the Bosch GWS 850 CE to the end of the intended section without leaving the laid line. In the case of stone, another nuance is important. The dust generated is dangerous for breathing, therefore, an effective suction of dirt should be provided, and work must be done in a respirator.
Positive reviews
Almost all Bosch angle grinders are renowned for sophisticated ergonomics in every way. And the adjusting capabilities, and the device handles with protective coatings cause only positive feedback. Despite its high performance, the power tool can be operated even with one hand - this is evidenced by user experience. In terms of the direct function of the processing machine, the Bosch GWS 850 CE also shows its best. Opportunities for working with stone and metal are implemented in accordance with advanced German standards.
Negative reviews
Like any tool, the German grinder is not free from flaws. It is noteworthy that they mostly relate to small, but unpleasant flaws of designers. In particular, there is a very short cable supplied with the Bosch GWS 850 CE. Reviews highly appreciate the performance of the device, but at the same time criticize it for its low autonomy. Lack of attachment to the outlet has long been a prerequisite in the development of power tools and a 1.5-meter cable Bosch seems a gross flaw. By the way, today the standard length is 3-4 m. There are negative reviews regarding noise insulation. According to experts, the loud noise of this device is connected with the work of helical gears. They not only make noise, but also transmit a high load to the machine, causing overheating. But it is thanks to these elements that the processing is carried out more accurately and practically without vibration. One way or another, noise insulation is not a fundamental technological condition for the production of grinders, so in most cases you can put up with this drawback.
Price issue
Professional equipment is not cheap. The difference with a budget power tool can be several thousand rubles. However, in the case of the Bosch GWS 850 CE, the price is quite acceptable and averages from four and a half to five thousand rubles. Given the high level of the manufacturer, the considerable power of the device and acceptable functionality, the price really looks attractive. But, with a detailed analysis of the grinder, everything falls into place. In addition to electronic adjustments and a really high-quality housing, the German company does not offer anything special. Therefore, the price justifies the purchase, but no more.
Conclusion
If you need a modern functional tool for periodically solving simple problems at home, then the modification of Bosch GWS 850 CE Professional may be one of the best options. The tool is easy to use, convenient and safe. In addition, the ability to process metal and stone makes it almost universal in terms of operation. However, if you plan to purchase an angle grinder for permanent work at construction sites, you will have to think about it. If we talk about the purely professional qualities of the device, it will not please anyone with anything special. Sufficient power, functionality at an average level - these same qualities are provided by less famous models of the segment. Ergonomics can be called the only trump card of this angle grinder, so if a short cable does not bother you, then you should consider this option.
