Реферат: A rotary cutting tool (20) has a cutting body (22) and a plurality of cutting inserts, including a first insert (24) removably secured in a first pocket and a second insert (26) removably secured in a second pocket. The first pocket opens out at a forward end surface of the cutting body, having a seat surface with an axial support wall (58) transverse thereto, and the second pocket is located axially rearward of the first pocket. The first insert has opposing front and back end surfaces, with a peripheral side surface extending therebetween which is in contact with the seat surface and the axial support wall. A first major cutting edge (42) of the first insert axially overlaps with a second major cutting edge (52) of the second insert, and in a side view of the cutting tool, a raised shoulder surface adjacent the axial support wall is at least partially obscured by the second insert.
