FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used in cutting tools with mechanical attachment of cutting plates. Cutting tool comprises holder and cutting plate fitted in its seat and clamped as required. Holder has bore to receive clamp cylindrical part and cylindrical bone with conical end surface intersecting the latter. Clamp guide part has threaded hole, its axis crossing said holder guide part bore, to receive the screw with conical surface eccentric about end conical surface of the holder cylindrical bore to interact therewith. Clamp guide part threaded hole is designed to locate its axis at angle to holder cylindrical hole axis. Angles of conical surfaces of said screw and holder cylindrical hole end surfaces are related by definite relationship.
