The invention relates to a carrier tool (1) comprising a clamping element (2) with a clamping element projection (3) and comprising a cutting insert (4) with a clamping recess (5) on the cutting insert surface (13) for machining workpieces. The clamping recess (5) has an annular indentation (9) with a recess base (7), and the indentation (9) transitions from the recess base (7) into the cutting insert surface (13) via an annular surface (8). The indentation (9) surrounds an elevation (10), the tip (11) of which lies above the recess base (7) and below the cutting insert surface (13). The clamping element projection (3) engages into the clamping recess (5) and thus clamps same on the carrier tool (1). In order to allow a pre-centering of the contour of the clamping element projection (3) and the contour of the clamping recess (5) when closing the clamping element (2), the contours of the clamping element projection and the clamping recess thus engaging into each other in a form-fitting and precisely positioned manner, the clamping element projection (3) has an annular contour (12) which surrounds the elevation (10) in the clamped state but does not contact the elevation and rests solely on the annular surface (8).
