ABSTRACT:
A reamer with at least one cutter plate that is held by at least one clamping jaw located in a recess in the head of the reamer and having an opening for a clamping screw is proposed, said reamer being distinguished by the fact that the clamping jaw (5) is shaped essentially as a triangle when viewed from the top, that the opening (23) for the clamping screw (7) is located in a corner of the triangle, and that the lateral surfaces of the clamping jaw (5) starting from this corner form guide surfaces (13, 15), which are provided with contact surfaces in the recess (9) in the head of the reamer. By using this clamping jaw, the cutter plate can be optimally clamped and aligned without weakening the main body of the reamer. Both the flank and lateral surfaces of the clamping jaw interact with the stop surfaces in a recess (9) in such a manner that optimal diversion of the clamping forces in the main body of the reamer also takes place.
