Abstract

The invention relates to a modular drill including a shank part with an end side. A cutting part can be connected to the shank part at its end side. The shank part has at least one torque transmission element which projects on the end side and has at least one torque transmission face for transmitting a torque in the rotational direction from the shank part to the cutting part. The cutting part has at least one torque receiving region for receiving the torque. The at least one torque receiving region has at least one torque receiving face which corresponds with the torque transmission face. The cutting part has at least one centering element for radially centering the cutting part in relation to the shank part. The cutting part is clamped to the shank part via a clamping element which acts at least predominantly in the axial direction.
