Facilitates maintenance operations and the location of carbon brushes with direct access. To increase the overall structural strength, the Bosch GWS 850 CE angle grinder was provided with reinforced plastic and armored winding.

The manufacturer strongly recommends keeping the tool clean and in good condition.

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.

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.

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.

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, the angle grinder all 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.


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.
