Abstract

A gearlike dressing tool coated with extremely hard abrasive grains like diamond or CBN. To reduce the manufacturing expenses, not all but only a portion of the teeth is coated. The remaining teeth remain uncoated. The coated teeth lie always directly side-by-side in a peripheral direction and have, including the coating, the same tooth thickness as the teeth which are not coated.
