ABSTRACT:
12. A rotationally drivable milling cutter has a cylindrical carrier body (10), which is equipped on its circumference with a plurality of cutting bodies (12) comprising a cutting material that is harder than hard metal. The cutting bodies (12) are embodied in platelike form and are each embodied and disposed such that the leading region of the radially outer circumferential edge forms the cutting edge, the adjacent side face (15) forms the first face with a negative rake angle, and the top face (17) diametrically opposite the bottom face forms the flank. To that end, the cutting bodies (12) are each secured with their bottom face on the end face of blind bores (30), in the circumferential face thereof, that are oriented with the angle to the shortest connecting line between the center point of the end face and the center longitudinal axis of the carrier body (10) such that the side face (15) adjacent to the cutting edge forms the predetermined rake angle.
