The article describes the analysis of the durability and lifetime of selected interchangeable cutting inserts used for turning based on the wear measurement of the cutting tool, flank wear namely. The experiment was carried out on one type of material, such as stainless steel 1.4404 according to DIN EN 10088-3. The measurements were made on two turning inserts of the same type from two different manufacturers - Sandvik coromant and Pramet tools. Evaluation of turning inserts wear was performed at four different cutting speeds. The value that was observed was the flank wear VB of the tool until the critical value was reached. Other different analysis have been performed, such as the length and shape of the chips analysis according to ISO 3685. Based on the results of the measurements, it has been found that the Pramet insert, which has a thinner layer of coating, has reached a longer life and allows heat to flow out of the cutting area. It can be considered that thinner coating can positively contribute to better machining of stainless steels, which could be helpful for machining companies. Cutting inserts wear research is realized at the Faculty of Mechanical Engineering of Jan Evangelista Purkyně University in Ústí nad Labem.
