A cutting insert includes a first chip surface, a second surface on an opposite side of the insert from the first chip surface, and a side surface extending between the first chip surface and the second surface, at least part of one first cutting edge being defined by an intersection of the side surface with the first chip surface. The side surface includes at least one recess, the recess including an insert supporting surface for supporting the insert relative to a protruding abutment surface on a toolholder and a flat auxiliary insert supporting surface for supporting the insert relative to a non-protruding, flat abutment surface.
