Abstract: An improved abrading tool adapted for being driven in rotation by a power tool is disclosed. The abrading tool includes a single piece housing having concentric inner and outer cylindrical walls. A plurality of abrading disc assemblies are in equal circumferentially spaced relation between the inner and outer cylindrical walls. Each abrading disc assembly includes an axle having an integral head and a key means adjacent the under side of the head adapted to be engagable with a keyed radial aperture of the inner wall for preventing rotation of the axle relative to the housing. A bushing is removably mounted on each axle between the inner and outer walls of the abrading tool. The bushing includes a flange formed at one end thereof adapted to be engagable with the outer wall of the housing. A plurality of abrading discs are rotatably mounted on each bushing wherein the flange is adapted to prevent contact between the abrading discs and the outer wall of the abrading tool.
