DEFINITION

Classification: 409/16

Plural hobs:

(under subclass 11) Apparatus including a first cutting tool and a second cutting tool each for performing the operation of that subclass wherein the cutting tools are capable of relative movement as assembled in the apparatus with respect to each other during the shaping operation.

(1) Note. A first cutting bit and a second cutting bit mounted on the same cutting tool holder are considered to be two edges of the same cutting tool rather than plural cutting tools.
