FIELD: the invention refers to metal working, a multi-part cutting instrument particularly to disk cutters. ^ SUBSTANCE: the cutter has a body, each its socket has a setting in with a cutting plate fixed on it. At that the socket is restricted with an upper, a low and a rear walls and is open in the direction of the periphery surface of the body and its lateral surfaces and the setting in is fixed in the socket with the aid of a fastening screw having a conic screw-die and a rod with threading and a nuts with conic exterior surface on which a knurl is made at interaction of the indicated conic surfaces of the screw-die of the fastening screw and a nut with a spring jaw. For increasing inflexibility of the body due to reducing radial extension of the sockets the fastening screw and the nut are located in a hollow opening fulfilled in the body and located under the low wall of the socket, and the spring jaw is fulfilled in the body and is designed for interaction with a lug fulfilled in the setting in. ^ EFFECT: increases effectiveness of a cutter. ^ 3 dwg |
