Abstract: This abstract describes a bead removal tool for removing the inner bead formed in joining plastic pipe. The tool comprises an axial cylindrical hub carrying a plurality of curved blades adapted to fit adjacent the inner surface of the pipe. The blades are rounded or tapered on their front ends and are sharpened to have a sharp cutting edge along the outer surface of the blades in contact with the wall. Each of the blades fits in contiguous fashion around the wall with each of the other blades. All blades are mounted by spring means from the hub, so that they are constantly pressed outwardly in contact with the inner surface of the pipe. Means are provided to move the hub forward, so that when a bead is reached it will be sheared off by the sharp edges of the plurality of blades.
