FIELD: process engineering.
SUBSTANCE: cutter comprises polygon cutting plates with opposed top and bottom surfaces. Bottom surface has peripheral lateral surface extending between top and bottom surfaces. Through locking hole is mad between said top and bottom surfaces. Cutter has, at least, two major cutting edges and, at least, two axial face angles between lines tangential to two major cutting edges. Note here that said axial face angles of major cutting edges differ.
EFFECT: reduced vibrations in cutting.
