DEFINITION

Classification: 83/468.8

Having curved cutting edge to make arcuate cut, plural nonaligned intersecting cutting edges, or spaced punches:

(under subclass 468.7) Device including on a single tool holder (a) a cutting edge that extends along an arcuate cutting plane when viewed normally to the work surface, (b) a first and a second cutting edge positioned on the same tool holder such that they cut the work along a continuous, but not straight path, or (c) spaced, generally aligned cutting edges that do not extend to the edge of the work.

(1) Note. A device having a curved cutting edge extending in part normal to the work-stop abutment is included in this and the indented subclass, as is a device having a first and a second cutting edge that serve together to cut a notch in the workpiece, wherein one of the edges extends normal to the work-stop abutment.
