The conditions for applying the method of drilling boreholes with simultaneous casing are considered. The most used tool designs, their advantages and disadvantages are shown. Present-day requirements for this tool are indicated. A new design is presented, which allows further drilling through the casing pipe of maximum possible diameter, simulation results are given. The operation of the device is described and a diagram of its use is presented.
