FIELD: machining of metals. SUBSTANCE: cutter has holder, cutting plate with front surface and supporting surface, with both surfaces being made spherical, fastening member with resilient protrusions, threaded support with resilient lugs and fastening screw. Threaded support is mounted in holder at the side adjacent to cutting plate supporting surface. Fastening screw is positioned in holder in axially aligned relation with respect to threaded support and biases resilient lugs of threaded support to cutting plate. Fastening member is disposed at side adjacent to front surface of cutting plate in axial alignment with threaded support. Cutting plate is arranged between resilient parts of threaded support and fastening member to increase vibration resistance of cutter.
