Abstract
A multi-edge reamer has a cutting region having a main body with a central axis. A first number of first cutters and a second number of second cutters extend from the main body. Each first cutter has a cutting edge and an adjoining circular grinding chamfer which forms a guide region for a corresponding first cutter and has a first width. Each second cutter has a cutting edge and an adjoining circular grinding chamfer which forms a guide region for a corresponding second cutter and has a second width. The first width is greater than the second width, the first number of first cutters is greater than the second number of second cutters, and all of the first cutters directly adjoin one another when seen in the circumferential direction so as to be arranged in a continuous group.
