The invention concerns a reamer comprising a base body (61), at least one groove (64) mortised in the base body (61), a cutting tip (1) inserted in the groove (64) and having at least one geometrically defined cutting edge (31, 35), in particular a cutting tip as per claims 1 to 5, a clamping device (43) fixing the cutting tip (1) in the groove (64) and comprising a locking dog (47) and a clamping screw (51), as well as an adjusting device (45) for adjusting the projection of at least one cutting edge (35, 31) of the cutting tip (1) beyond a peripheral surface (73) or beyond at least one guide edge (75, 77) of the reamer (10). The reamer is characterized in that the adjusting device (45) comprises only one adjusting screw (55) which acts directly or via an adjusting element (57), on a first end of the cutting tip and in that the cutting tip (1) rests, with its second end, directly on the bottom (65) of the groove (64) or on a second sealed adjusting device. The invention also relates to a cutting tip (1). |
