In known cutter heads, the centrifugal forces occurring at high rotational speeds may cause the occurrence of dilatations permitting the cutting edges of the cutting tools to shift from their adjusted positions. An object of the invention is the provision of a cutter head capable of being accurately and reliably adjusted for operation also at high rotational speeds. According to the invention, a clamping wedge 13 is provided with a skewed clamping surface 21b adapted to cooperate with a contact surface 21a of a cutter blade carrier 2 for clamping it in a groove 20 of a mounting body 1. The invention also proposes the provision of a prism wedge clamping system 10 for supporting the cutter head carrier 2 in the radial direction relative to the mounting body 1.
