CUTTING INSERT, CUTTING TOOL, AND METHOD OF MACHINING

摘要

A cutting insert (21) includes a body having a first surface, a second surface, and an intermediate surface. The intermediate surface includes a generally cylindrical main surface (31) and at least one recess surface (33) extending radially inwardly from the main surface, the main surface and the recess surface extending between the first surface and the second surface. Cutting edges (39) are defined by intersections between the main surface (31) and the recess surface (33).
