Abstract
In cutting tools employing disposable inserts an indexing shoulder is generally provided on the body of the tool. When exposed to excessive force the shoulder may be damaged and the tool difficult to repair. This invention proposes a replaceable seat which is indexed to the tool, and wherein the seat is provided with an shoulder against which the insert is indexed. In the preferred embodiment the insert is provided with a transverse channel in its seating surface and the seal with a mating land. The arrangement provides for forward and reverse indexing of the insert, and is of particular utility in positive rake and tracer cutting tools.
