摘要

Machine reamer comprises a cutting block (10) with guiding surfaces (40) facing each other or facing away from each other in the direction of the longitudinal axis (Z) and guiding surfaces (48) facing each other or facing away from each other in the direction across the longitudinal axis of a tool holder (2). The guiding surfaces are arranged on the cutting block in the direction of the longitudinal axis spaced from the front side of the cutting block in the advancing direction. An independent claim is also included for a cutting block for a machine reamer. Preferred Features: The guiding surfaces extend close to the interacting lines of the interacting reaction forces arising on the cutting edges (12). Rib-like protrusions (42) are formed on radially opposed side surfaces on the cutting block.
