Abstract
A gear or rack-shaped tool for precision machining of tooth flanks of gears is provided with a coating of a hard material like diamond or cubic bornitride (CBN). In order to be able to apply this coating without any problems, the tool includes two connected halves. Each half includes a base member with teeth which project axially beyond one side of the base member every second tooth being removed. The projecting teeth of each half project into the gaps created by the teeth removed from the other half.
