A round cutting insert includes a bottom surface, a clearance side surface and a top surface. The top surface includes a chip control feature in the form of a continuous, circumferential depression formed by a substantially planar bottom surface and a pair of upward sloping substantially planar side walls that form an angle with respect to the top surface. The chip control feature may also include a plurality of radially offset bumps located in the depression. The bumps may have the same size and shape, or may have a different size and shape. The top surface also includes an elevated island having one or more indexing marks for easy indexing of the cutting insert.
