Abstract: A cartridge for a grooving tool holder extends along a mid-thickness plane by being bordered in the mid-thickness plane by peripheral surfaces of the cartridge. The peripheral surfaces of the cartridge include a clamping surface, a back surface for the fixation to the grooving tool holder along a screwing direction, and a front surface. The cartridge has a coolant channel extending along a direction from the back surface to the front surface. The screwing direction and the direction of extension of the coolant channel are both included in the mid-thickness plane of the cartridge. A grooving tool holder includes an upper front surface for fixation by screwing to the back surface of the cartridge.

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°.
