A skiving and roller burnishing tool for cutting and burnishing the interior of a cylinder or other workpiece is disclosed. The cutter assembly is mounted on a drive shaft which drives the cutter assembly through the interior of the cylinder to cut the interior of the cylinder to its approximate final diameter. A roller race is located aft of the cutter assembly, and has a frustoconical configuration in section which tapers outwardly in a forward direction. A plurality of rollers are distributed circumferentially about and bear on the roller race. The rollers are also frustoconical in section so that the outermost surface of each roller is parallel to the axis of the drive shaft. A roller cage engages the rollers and restricts movement of the rollers while allowing them to rotate about their axes and translate radially to a limited degree. The roller cage is movable in an axial direction relative to the drive shaft. A selected axial force is applied to the rollers in a forward direction so that the rollers are biased outwardly by the frustoconical roller race and apply a selected radial burnishing force to the interior of the cylinder.
