The boring head has a tool body (2, 38), to which two cutter holders (3, 4; 22, 23) arranged offset from one another by 180° are fastened. The cutter holders (3, 4; 22, 23) are mounted on a clamping surface (11, 26) in a slidable manner for radially adjusting the cutters (5). The clamping surface (11, 26) has a first partial clamping surface (11a, 26a) for the one cutter holder (3, 4; 22, 23) and a second partial clamping surface (11b, 26b) for the other cutter holder (3, 4; 22, 23). These two partial clamping surfaces (11a, 11b; 26a, 26b) are offset in the axial direction by a certain extent. The two cutter holders (3, 4; 22, 23) have different heights with respect to the cutters (5) in accordance with this extent and in addition can be optionally fastened to and radially adjusted on the first partial clamping surface (11a, 26a) or the second partial clamping surface (11b, 26b). The boring head permits the conventional roughing work and is especially stable while being produced at a low cost.
