<p>The invention proposes a reamer having a base (3), at least one cutting tip (13) disposed essentially parallel to a face (11) of the reamer (1) that comprises a geometrically defined major cutting edge (27) and a geometrically defined minor cutting edge (29) and is held on a contact surface (19) of the base (3) of the reamer (1) by a tightening screw (39) penetrating the cutting tip (13), with a back (17) of the cutting tip (13) resting on the contact surface (19), having an adjustment unit having an adjustment screw acting on the cutting tip (13) that introduces adjustment forces into a lateral surface of the cutting tip (13). The reamer is characterized in that the recess (35) accommodating the tightening screw (39) penetrating the cutting tip (13) comprises a clamping region (57) and in that the distance from the clamping region (57) to the rear (17) of the cutting tip (13) measured perpendicular to the rear (17) is equal to the distance from the engagement region of the adjustment forces to the rear (17) of the cutting tip (13) measured perpendicular to the rear (17) of the cutting tip (13).</p> |
