(under subclass 199) Device including a plurality of cutting edges disposed about the tool-axis and positioned at different radial distances from the tool-axis.
(1) Note. This subclass is not intended to include a reamer having a section wherein the cutting edge(s) is in a cylinder parallel with the tool-axis and a tapered lead section wherein the cutting edge(s) lie in a cone concentric with the tool-axis because it cannot be said that the cutting edges are at different radial distances from the tool-axis.
(2) Note. Included herein is a tool having a cutting edge(s) in a first cone concentric with the tool-axis and a cutting edge(s) in a second cone also concentric with the tool-axis, even if the cutting edges meet.
