— the design and principle of operation of such tools resemble vibro-grinding (delta-grinding) machines — the material is processed due to the vibration of the working nozzle. However, renovators do not have such a narrow specialization and can be equipped with nozzles of various types, which allows you to carry out various types of work — actually grinding, cutting, cleaning, and much more. Such models are usually not designed for large volumes of work, however, they often surpass specialized tools in terms of accuracy of processing and the ability to reach hard-to-reach places.
