DEFINITION

Classification: 82/83

(under subclass 70.1) Devices including means to cause the tool(s) to revolve about an axis passing through said tool.

(1) Note. The incremental shift of a tool about its axis to present a new portion of the cutting edge to the work (either between cutting strokes or during cutting strokes) is not considered tool rotation for this subclass. See subclass 100 for tool adjustment.
