The article evaluates durability of punches and cutting tools when cutting of the cut-outs. Durability of punches made of the same material without coating, with the TiCN-MP coating and with the TiN coating is compared. Durability is evaluated by the tolerance of the cut-outs. Border durability, which requires grinding of the tool, is a determined durability, at which the deviation of the tolerance of a cut-out is at the lowest border. By comparing the dependency of change of the holes’ dimensions on the number of strokes in the case of all three types of punches, it can be stated that the durability increased by 10–12 times in the case of the tools with coatings.
