In this device, the bit 7 is driven through the bit 7 and the bit 7 is used to drill into the ground. This turbo drill is equipped with a bypass valve 12 that bypasses a part of the mud flowing into the turbine shaft 3a to a passage 3b provided in the turbine shaft 3a. 2. A valve element 13 that allows the bypass valve 12 to move freely along the axial direction of the turbine shaft 3a, a means for biasing the valve element 13 in the closing direction, and a means for biasing the bypass valve 12 in the mud flowing into the turbine 3, Utility model registration claim 1, comprising a detection turbine blade 15 that generates a brake torque on the valve body 13 to operate the valve body 13 in the opening direction when the rotation of the valve body 3a exceeds a set value. Turbo drill as described in section.
