The head is provided with at least one radially extending slot ( 10 ) receiving a plate ( 1, 2 ) of the reamer. The retaining device ( 14, 15 ) has a component which engages with a feature of the plate of the reamer. The feature is proximate the axis of rotation of the reamer in order to centrally retain the plate in the slot.
