The aim of the thesis is to evaluate the possibilities of increasing the life of the woodworking tools by different methods. The thesis contains a theoretical part that serves as a resource for a more practical part of the work. The theoretical part is focused on material and structural analysis of tools, analysis of the working environment and the possibility of increasing the life of tools. Two saw blades were selected for analysis of selected tool lifting methods. Input analysis of the samples was done with the aim of obtaining information about the materials. Additionally, the samples were coated with three coatings TiAlN, AlTiN and CrN/TiN. Analysis of coated tools surfaces was performed using various methods by examining mechanical properties as well as by analysing the Keyence VHX-2000 optical microscope and the Tescan Vega3 XM scanning electron microscope. The conclusion of the practical part is devoted to the evaluation of the results of the experiment, on the basis of which the recommendations were put forward for practice.
