Apparatus is provided for profiling the end faces of pipes or tubes. The apparatus comprises a shaft one end of which is insertable into the open end of a pipe or tube to be profiled, collett means on said one end of the shaft, and cutting means rotatably mounted on said shaft for profiling the end face of the pipe or tube. The collett means comprises first and second screw threads of opposite hand on said one end of said shaft, a nut in threaded engagement with each of said screw threads, the nuts being movable in opposite directions along said screw threads when the shaft is rotated, and engaging means supported on said nuts and movable radially of said shaft into or out of engagement with the internal surface of the pipe or tube when the nuts are moved along said screw threads by rotation of said shaft. The screw threads are preferably coarse threads which with the differential effect of the opposed screw threads provides rapid engagement and disengagement of the collett means.
