Abstract
A reaming tool for use in reaming a bore includes a body adapted for location in a bore. The body defines a rotor of a rotary drive arrangement. A shaft adapted for location is disposed in the body. The shaft defines a stator of the rotary drive arrangement. A seal element is disposed between the shaft and the body. The seal element defines a bearing surface for permitting sealed relative rotation of the rotary drive arrangement. The tool includes a reaming member, wherein relative rotation between the body and the shaft facilitates reaming of the bore by the reaming member.
