An improved mandrel is provided for use with a tube-finning machine. The mandrel is mounted to a stationary arbor and supports a tubular member during a tube-finning operation. The mandrel comprises a stationary body axially mounted to the arbor and a lubricated bushing which is rotatably mounted on the body. The bushing facilitates rotation of the tubular member relative to the body and supports the interior surface of the tubular member during the finning operation.
