  • Cutting insert and a cutting tool for milling square shoulders
    Patent number: 10512977
    Abstract: A cutting insert for milling square shoulders has side surfaces each provided with a major cutting edge connected to an associated wiper edge 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 arranged consecutively with respect to a direction of the extension of the major cutting edge and make different angles with a normal to a bottom surface of the insert. A border forming a limit of the support surfaces most distant to the bottom surface 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 towards the wiper edge.
