Abstract: An indexable and double-sided round cutting insert includes an upper and lower side. A center axis extends between the upper and lower side and a median plane extends perpendicular to the center axis and is situated halfway between the upper and lower side. A side surface has an upper and lower positive clearance surface at an upper positive clearance angle with respect to an upper cutting edge and a lower positive clearance angle with respect to a lower cutting edge. A plurality of protrusions extends along the side surface and protrude in a radial direction perpendicular to the center axis. Each protrusion includes an outer surface, which along the center axis, extends such that a first radial distance from the center axis to the outer surface in the median plane is at least equal to or greater than a second radial distance from the center axis to the outer surface.

Abstract: An actuatable boring bar is configured to place a cutting insert cartridge received onto the boring bar in a cutting position when the centrifugal force generated by the rotation of the boring bar about the rotation axis reaches a centrifugal force threshold and in a non-cutting position when the centrifugal force generated by the rotation of the boring bar about the rotation axis is below the centrifugal force threshold. The boring bar is further configured so that the cutting insert cartridge can be set-up onto the boring bar in the cutting position.

Abstract: A cutting tool for face milling includes insert pockets for the fixing of cutting insert. The cutting inserts can be fixed in the insert pockets, wherein the cutting inserts and insert pockets are designed such that, when the cutting inserts are fixed within the corresponding insert pocket, each cutting insert presents: a primary and a secondary cutting edge. The intersection between the primary and the secondary cutting edge of one cutting insert being axially inwardly and radially outwardly offset from the intersection between the primary and the secondary cutting edge of another cutting insert. A lead angle defined between the primary and the secondary cutting edges is less than 30°.
