Class 407
CUTTERS, FOR SHAPING
Class Definition:
Class 407 is the residual locus of the device to be attached
to the driven spindle or to the stationary tool post of a
machine intended to shape work by a sharp edge or point
cutting that work to remove a chip therefrom; wherein, there
is no relative movement between the sharp edge or point and
the other claimed structure during cutting.
SCOPE OF THE CLASS
