Document Type and Number:
Japanese Patent JP6695336
Kind Code:
B2
Abstract:
A cutting insert (4) for milling square shoulders has side surfaces each provided with a major cutting edge connected to an associated wiper edge (22) on an adjacent side surface of the insert. The side surface provided with the major cutting edge has two generally flat and non-coplanar support surfaces (23, 24) arranged consecutively with respect to a direction of the extension of the major cutting edge (20) and make different angles with a normal to a bottom surface (15) of the insert. A border (27) forming a limit of said support surfaces (23, 24) most distant to the bottom surface (15) is inclined with respect to the bottom surface so that the distance of this border to the bottom surface increases in a direction of extension of the cutting edge (20) towards the wiper edge (22).
