The invention relates to a tube cutter, especially for plastic tubes, which comprises a housing that can surround the tube and having a rotation guide gripping the tube. The tube cutter has a cutting tool which can be sunk into the outer surface of the tube, having a lengthwise guide and a tool holder movable therein. The cutting tool has a cutting edge which runs at an angle to the direction of movement of the tool holder and lies substantially in a plane passing through the rotational axis. By these means it is possible to produce bevels with the cutting edge. To solve the problem of shaping the bevels on the tube periphery as uniformly wide as possible even with non-circular tube cross-sections, and to avoid an irregular force requirement at the end of the separating operation, it is proposed according to the invention to arrange a resilient member between the tool holder and the spindle and to provide the tool holder with a spacing guide device for guiding the cutting tool relatively to the outer surface of the tube.
