One of the major problems when machining soil mass is wear of working tools. The process consists of many factors related to, amongst other things, the work item, the properties of the soil and the working process parameters. During surgeries working big impact on the consumption process parameters are working, such as the type of cutting, machining depth and speed of its implementation. So far, there is no work that would have recognized the issue of the impact of cutting speed on the course wear. Processes which occur in the surface layer material are associated with changes in its mechanical properties, physical and chemical properties. The paper analyses the process of wear steel 38GSA and the same steel weld electrode EstelMn60. Studies were conducted in laboratory conditions by the “spinning bowl” method. During the tests carried out etering of samples depending on the type of road friction and the treated pulp. The results found that with increasing speed decreases wear intensity weight steel 38GSA. And for the deposit EstelMn60 there was no clear effect of speed on wear intensity. It is also noted that a significant impact on the amount of abrasion is the percentage of alloying elements
