FIELD: `the invention refers to metalworking, multi-part cutter. ^ SUBSTANCE: the cutter has a body. In each socket there is a setting in with a cutting plate installed on it. The socket of the body is restricted by 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. The setting in is fastened in the socket of the body with the aid of a fastening screw having located in a hollow opening a conic screw-die, a rod with threading and nuts with conic exterior surface on which a knurl is made. A lug is fulfilled from the side of the rear wall for increasing inflexibility of the body at the expense of reducing the radial extension of sockets in the socket of the body. The lug is located between the upper and the low walls and has an opening whose lateral surface is designed for interaction with the rod of the fastening screw and a groove covering the mentioned lug is fulfilled in the setting in from the side directed to the rear wall of the socket of the body. ^ EFFECT: increases effectiveness of the cutter. ^ 3 dwg |
