The cold bulk forming is a technology that is commonly used in many industrial enterprises. Even though nowadays high demands are posed on labour productivity, quality and own production costs, the findings from practice suggest that not sufficient attention is paid to the issue of tool management. Also, theoretical backgrounds and knowledge in this area are not processed in a sufficiently detailed and comprehensive way. This paper deals with the issue of prediction of the wear surface of the forming tools and their subsequent renewal. The research at selected materials was focused on the course of their straining in contact of the blank with the tool in the process of cold bulk forming. The experiments were based on a simple performance of the conventional upsetting test. On the basis of analysis of the results the mechanism of tool wear by abrasion was determined and its impact on the service life time of the tool and also the possibility of influencing the quality of final parts were evaluated.
