An in-pipe local drilling device, comprising a transmission flexible shaft (100), a support (200), a driving device (300), a drilling device (500), and a connecting device (600). The support (200) is circular, and is coaxially connected to the first end of the transmission flexible shaft (100); several rollers in contact with the inner wall of a pipe are arranged at the periphery of the support (200) at intervals; the driving device (300) is connected to the second end of the transmission flexible shaft (100), and transfers a torque force to the support by means of the transmission flexible shaft, so as to drive the support to move along the length direction of the pipe; the drilling device (500) and the connecting device (600) are positioned on one side of the support (200) away from the driving device; the drilling device (500) is connected to the support (200) by means of the connecting device (600). The device can convey the drilling device to a preset position to carry out local treatment on the inner su
