The article provides information on the development and study of a mathematical model for changing the durability of a new progressive combined tool. Currently, one effective way to increase productivity in automated manufacturing is to concentrate operations or transitions. With a high degree of operations concentration, the complexity of the kinematics of the equipment increases, its reliability decreases, therefore, downtime and the production cost are rising. The transitions concentration leads to the tool design complexity increasing, while the equipment can have simple kinematics of movements. The compatibility of operations or transitions depends on the required machining accuracy and surface roughness. The accepted procedure for performing operations and transitions determines necessary tool type. The most efficient concentration of operations or transitions can be achieved by using combined tools. Combined tools can be used in the treatment of both stepped and smooth cylindrical holes, which make up 35% of all surfaces used in mechanical engineering. Therefore, this study is devoted to solving the problem of increasing productivity and reducing the cost of threaded holes processing through the use of a new combined tool called the drill-tap.
