The clamping finger being secured on the carrier tool via a clamping bolt so that when tightening the clamping bolt, the clamping finger pulls the cutting insert into the recess. A sickle-shaped engagement element engages into the clamping depression of the cutting insert being arranged on the lug. The clamping bolt has a clamping head overhanging its shank. The clamping head is seated on an angled locating surface of the clamping finger with respect to the axis of the clamping bolt, wherein said surface is arranged so compression force of the clamping finger on the cutting insert is enhanced. The lug has a clamping surface for bearing on the rake face of the cutting insert.
