FIELD: process engineering.
SUBSTANCE: cutter has body and plug-in cutting plate with main part. Note here that said body has slot to accommodate said cutting plate. Note that said main part has central section with axis and, at least, one convexly-curved centring surface directed there along as well as, at least, one dog extending from central section. Note that said body slot has inner surface interacting with, at least, one of said centring surfaces. Note that said centring surfaces represent partial surfaces of imaginary lateral surface of conical section converging toward tool front while slot inner surface is shaped in a definite manner. At least one centring surface extends up to face side of cutting plate main part.
EFFECT: stable cutting.
