Claim:
A tool for chip removing machining, comprising: a basic body and two replaceable cutting inserts, each insert including a chip-removing main edge situated between a chip surface and a clearance surface, a first one of the inserts of which precedes a second one of the inserts during machining of a workpiece, the cutting inserts overlapping each other in a zone defined by a borderline along which a surface generated by the main edge of the first cutting insert is intersected by the main edge of the subsequent, second cutting insert during machining of the workpiece, wherein the chip surface situated along the main edge of the second cutting insert, that afterwards intersects the surface generated by the main edge of the first cutting insert, includes primary and secondary sections which have different shapes in cross-sections spaced-apart along the main edge in order to form a primary part edge and a secondary, reinforced part edge arranged to intersect the surface generated by the main edge of the first cutting insert.
