FIELD: machine building.
SUBSTANCE: group of inventions relates to machine building and may be used in milling. Tangential cutting plate comprises two opposite lateral surfaces and peripheral surface located between them with four identical face surfaces. Line of intersection of end and side surfaces make major cutting edges, line of intersection of end surfaces and adjacent end surfaces - auxiliary cutting edges. Each of the main and auxiliary cutting edges has a front surface directed inside the cutting plate. On side view of cutting plate main cutting edges are made concave. Disclosed is a milling cutter for use of said cutting plate.
EFFECT: processing of part rectangular ledges.
