摘要：
In a reamer having two diametrically opposite, replaceable cutting blades on its cutter head, an axially elongated rib having a circumferential face approximately cylindrical about the axis of rotation is arranged in each of the two gaps circumferentially bounded by the cutting edges of the blades, thereby assuming the guide function of conventional multiple blades in the reamed hole, and permitting the blade edges to be provided with a relief angle of 5.degree. or more.
