According to the present invention the radial feed mechanism comprises a hydraulic cylinder on the rod of which is rigidly fixed a holder connected with the housing of the radial feed mechanism by springs which ensure the cutting force of the cutting tool. At one end the springs bear against the housing of the radial feed mechanism while at the other end they bear against the holder rotated by a drive mounted on the tool head body and the shaft of said drive is rigidly connected with the housing of the radial feed mechanism. The housing of the radial feed mechanism carries a slide valve whose rod interacts with the profiled surface of a master form rigidly fixed on the tool head body. The holder is provided with rollers for tracing the internal surface of the welded pipe. The advantage of the device according to the present invention resides in that it ensures removal of flesh regardless of its temperature. Besides, the device allows the flash to be removed uniformly around the perimeter of the joint even in case the welded pipes are out-of-round. Further, the device allows to maintain practically constant cutting force during the flash-removing process.
