A roller reamer includes a roller assembly deployed in a corresponding axial recess in a tool body. The roller assembly is retained in the axial recess via compound wedging action provided by at least one retention assembly. The retention assembly includes first and second wedges, the first of which converts a substantially radially directed force to an axially directed force and the second of which converts the axially directed force to a cross-axially directed retention force that retains the roller assembly in the axial recess.
