Abstract
A gear cutting tool wherein each cutting blade group includes two differently positioned but identical cutting blades (41, 40) such as an one outside and one inside blade. The inventive blade arrangement only requires a single type of blade (30) in order to simultaneously cut the convex and the concave tooth flanks of a gear as well as the root fillet and root bottom portions of tooth slots. The cutter system allows radial adjustment of the outside cutting blade and the inside cutting blade independently of one another. Additionally, inside and outside cutting blades may be exchanged with one another.
