The article presents the results of the experimental verification of the deep hole boring bar tool model. The aim of the work was to obtain a verified boring bar tool model, which in further scientific research will be a starting point for creating a prototype of a tool with a new design, in which dynamic properties will be improved. The research was divided into two stages. In the first stage, modal studies of the model and the real object were carried out. The obtained discrepancy between numerical and experimental results below 8% allows to state that the model is characterized by dynamic properties occurring in the real boring bar. In the second stage of the research, static tests were carried out. The object was loaded with forces of 98.6 N, 195.0 N, 293.8 N. The obtained slight discrepancy in the results of numerical and experimental tests below 3% allows to state that the model reflects the static properties of the real boring bar. The high convergence of the theoretical and experimental results allows for the conclusion that the numerical model has been verified positively.
