The presence of an angle grinder in the household makes it easy to solve the problem of processing hard surfaces in the process of repair work. In addition, this equipment, also known as a "grinder", may be needed in plumbing activities, as well as when removing unwanted raids. Today, there are many angle grinder models from different manufacturers, but it is recommended to make a choice in favor of reputable companies. These include the Bosch GWS 850 CE Professional, which comes in a wide range of equipment, is distinguished 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, since competing grinders also have something to offer.
General information about the model
The device is presented in the line of professional equipment, which is designed for a wide range of operations. In particular, the angle grinder Bosch GWS 850 CEcopes with the processing of metal materials, stone and wood. The operator will be able to perform cutting, sanding, brushing, as well as remove traces of paintwork and rust. High power helps the tool to perform the above actions qualitatively. However, this does not affect the dimensions and ergonomics of the device. The user will be able to easily control all the capabilities of the unit without outside help - of course, basic training and knowledge of the handling of the angle grinder will still be required.
In addition to compactness and maneuverability, the device will please the owner and electronic filling. Actually, the introduction of control systems with a hint of intelligence has long been practiced by other manufacturers, however, in the Bosch GWS 850 CE angle grinder, this concept is implemented most successfully and without serious errors.
Specifications
The belonging of this device to professional models is indicated not only by advanced electronic systems, but also by the basic technical potential. So, the German grinder has the following characteristics:
- Power potential - 850 W.
- The number of revolutions is adjustable from 2,800 to 11,000.

- Spindle thread size in length - 2.2 cm.
- The weight of the device in the complete set is 2.6 kg.
- The weight of one tool is 1.6 kg.
The main thing that pays attentionthe tool is a high level of power and a wide range of revolutions. 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 the electronic setting system. Compared with the adjustment in traditional models, this innovation allows you to set the machine to the optimal parameters for working with a specific material. In addition, the Bosch GWS 850 CE unit is equipped with a soft starter. This means that a sharp start of processing is excluded, as a result of which the greatest 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 negative effects from voltage surges.
In order for the operator to easily and quickly change the components of the machine, a fixed spindle is provided in its design. Facilitates maintenance operations and the positioning 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, on the other hand, they increase the wear resistance of the tool.
Maintenance
The manufacturer strongly recommends keeping the tool clean and in good conditiontechnical condition. To do this, you must use work items that match the characteristics of the material and the processing conditions. It is also necessary to regularly check all the slots and ventilation openings of the machine, since their contamination can lead to breakage directly during operations. In the event that 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 the wiring diagram of the device - then, in accordance with it, independently determine the malfunction and eliminate it. However, it is not recommended to perform such actions without appropriate preparation.
Exploitation nuances
You can start working if several conditions are met. Firstly, the tool must be in good condition, and all its components and functional parts must be correctly selected in terms of the upcoming processing. Secondly, the workpiece must be securely fixed. The Bosch GWS 850 CE angle grinder must not be subjected to excessive pressure during operation. Even the processing of coarse abrasives should be carried out with moderate tension, properly grasping the handle of the tool. After completing the operation, you do not need to immediately turn off the machine. Leave it idling for a few minutes. This must be done, as sudden voltage drops in mechanical elements adversely affect the durability of the device.
Each material has its own characteristics of processing. For example, in the process of cutting metal, the working body should be driven against rotation. This will allow you to bring the Bosch GWS 850 CE to the end of the intended segment without exiting the laid line. In the case of the stone, another nuance is important. The generated dust is dangerous for breathing, therefore, effective suction of dirt should be provided, and work should be done in a respirator.
Positive feedback
Practically all Bosch angle grinders are famous for their thoughtful ergonomics in every respect. Both the adjustment possibilities and the arrangement of handles with protective coatings cause only positive feedback. Despite the high performance, the power tool can be operated even with one hand - user experience testifies to this. In terms of the direct function of the processing machine, the Bosch GWS 850 CE also performs at its best. Opportunities for working with stone and metal are implemented in accordance with advanced German standards.
Negative reviews
Like any instrument, the German grinder is not without flaws. It is noteworthy that for the most part they are small, but unpleasant design flaws. In particular, a very short cable is noted, which is 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. Being tethered to an outlet has long been a must in the development of power tools and the 1.5 meter Bosch cableseems like a major oversight. By the way, 3-4 m is considered the standard length today. There are also negative reviews for sound insulation. According to experts, the strong noise of this device is associated with the operation of helical gears. They not only make noise, but also transfer a high load to the machine, causing overheating. But it is precisely thanks to these elements that the processing is carried out more accurately and practically without vibrations. One way or another, sound insulation is not a fundamental technological condition for the production of angle grinders, so this drawback can be put up with in most cases.
Question of price
Professional equipment is expensive. 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. Taking into account 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 case, 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 the periodic solution of simple tasks at home, then the Bosch GWS 850 CE Professional modification may be one of the best options. The tool is easy to use, convenient and safe. In addition, the possibilityprocessing of metal and stone makes it almost universal in terms of operation. However, if you plan to buy an angle grinder for permanent work on construction sites, you will have to think about it. If we talk about the purely professional qualities of the device, it will not please with anything special. The power is sufficient, the functionality is at an average level - the 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.
