Cutting insert

A cutting insert comprising:

• a body having three vertices, an upper face, a lower face, and flank faces joining the upper and lower faces;
• at least one cutting edge at an intersection between the upper face and the flank faces;
• and
• a generally triangular-shaped island surrounding a central axis of the cutting insert;
• the island comprising three sides which are each non-straight, and which do not fully run in parallel with respect to an outer contour of the body;
• the island being higher in elevation than at least one portion of the upper face;
• the body comprising three leg portions, each leg portion being defined by two of the flank faces converging toward a corresponding one of the vertices;
• wherein, for each leg portion:
• the upper face defines a surface area between the two flank faces which converge toward a corresponding vertex;
• and
• the island covers a minority of the defined surface area;
• wherein the shape of the outer contour of the body is indented with respect to an imaginary triangle defined by the vertices of body.
