Opis
Ejecución:
Alma reforzada y afilado especial, con lo que se consigue un filo transversal cortante con alta precisión de centrado. Los filos principales rectos con un ligero redondeo de los bordes y una forma de ranura especial generan virutas cortas.
Nota:
Longitud de la ranura de viruta LC = L2 + 1,5 × DC.
