DEFINITION
Classification: 407/
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
Cutting tools for shaping (as distinguished from subdividing) generally to be used in a "milling, gear cutting, or planing" machine or in a lathe, will be found in this class unless specifically provided for in another class. Included herein is all the structure normally replaced in changing from a first to a second tool, unless there is relative movement between part of the normally replaced structure and the cutting edge.

GLOSSARY:
Terms in the definition of this class followed by an asterisk (*) will be found to be defined in this section. Terms frequently appearing will be accompanied by an asterisk only where the exact meaning of the term is deemed particularly important. CUTTER
See Tool*.
TOOL
A distinct unitary piece of material or plurality of unitary pieces of material permanently affixed together having a sharp edge or point for penetrating work and thereby directly effecting the operation of this class either by itself or by cooperation with another tool. A tool may have a plurality of edges or points for penetrating the work either concurrently, sequentially, or selectively and is adapted to be separably attached either directly or via a tool holder* to a machine*.
TOOL HOLDER
A device consisting of a single element or a plurality of elements having means to removably carry a tool* and adapted to be separably attached to a machine* for supporting the tool against gravity and against the reaction of working force.
TOOL SEAT
That part of the tool holder* that is in direct contact with the tool. The tool seat may be integral with the remainder of
the support of may be separably carried thereby.
MACHINE
An assembly of components adapted to support work and a tool* and bring them together to perform a shaping operation by piercing the work with the tool and removing a chip therefrom. Specifically, a machine for use with the cutter of this class will be a "milling, gear cutting, or planing" machine or a lathe.
WORK Material which is intended to be subjected to an operation of this class.
WORKPIECE
An object which is intended to be subjected to an operation of this class.
