The ornamental design for a cuttinginsert, as shown and described.
FIG. 1 is a perspective view of a surface color pattern for a cutting insert showing my new design. The mesh lines indicate that: (a) there is a gold colored band which extends around the cutting insert along the cutting insert's side walls; and (b) in the vertical direction, the gold colored band extends along a medial portion of the side walls. The upper and lower portions of the cutting insert's side walls, on either side of the gold colored bands are black.
FIG. 2 is a first side view of a surface color pattern for a cutting insert, the other side views being the same; and,
FIG. 3 is a top view of the cutting insert, showing its footprint. No claim is being made to the appearance of the top or bottom surfaces.
The drawing is lined for color.
The broken lines in the drawings depict unclaimed environmental subject matter.
