<p>A cutting tool assembly (10) includes a cutting tool (12) and an indexable cutting insert (14) having an insert index axis (Q; fig 1C). The cutting insert (14) includes parallel insert first and second sides (22A, 22B; fig 2B) connected by an insert peripheral surface (24; fig 2B) that extends peripherally around the cutting insert (14). At least one clamping hole (26; fig 2B) opens out to one or both of the insert first and second sides (22A, 22B) and at least a portion of the clamping hole (24) is in a clamping region (CL; fig 1C) of the cutting insert (14). The insert peripheral surface (24) includes cutting edges (18, fig 1C) that are spaced-apart and extend from the insert first side (22A) to the insert second side (22B). Along a width direction (Dw; fig 2B), which is perpendicular to the insert first and second sides (22A, 22B), each of the cutting edges (18) is wider than the cutting insert (14), at least at the cutting region (CU; fig 1C) of the cutting insert (14).</p> |
