Abstract
The body of a gear hob consists of a plurality of adjacent disc-shaped segments. A helix of successive cutting teeth extends around the body and is formed by the adjoining peripheries of the segments. First and second metal cutter plates are replaceably mounted on the teeth flanks. The first cutter plate is mounted at the top of a respective tooth flank and the second cutter plate is mounted on the opposite flank. The first and second cutters alternate along the helix at each side of the teeth and their cutting paths overlap.
