Abstract
A reamer is proposed, having a basic body (3), at least one cutting tip (13) disposed essentially parallel to a face (11) of the reamer (1), which has a geometrically defined major cutting edge and a geometrically defined minor cutting edge (29, 27), and is held on a support surface (19) of the base body (3) by a tightening screw (39) that penetrates the cutting tip (13), where a back (17) of the cutting tip (13), which is polygonal in a bottom view, lies against the support surface (19), and having an adjustment device having an adjustment screw that acts on the cutting tip (13), which screw introduces adjustment forces into a side surface of the cutting tip (13). The reamer is characterized in that the ratio of the diameter (55) of an imaginary in-circle (53) that is tangential to the side edges (41, 41', 45, 45') of the back (17) of the cutting tip (13), relative to the thickness (d) of the cutting tip (13), lies in a range of 1.0 to 1.5, preferably in a range of 1.2 to 1.5.
