摘要： A cutting tool includes a cutting insert and a toolholder including at least one insert supporting surface. A first clamp is adapted to apply a clamping force in a first direction to clamp the insert to the insert supporting surface, and a second clamp is adapted to limit rotation of the insert about an axis extending substantially in the first direction. The toolholder includes a second insert supporting surface. The second clamp applies a clamping force to the insert in a second direction to clamp the insert to the second insert supporting surface, and the second insert supporting surface is disposed on an opposite side of the insert from the second clamp.

摘要： An indexable milling insert has a trigon shape and includes a mounting hole placed centrally in the milling insert, an upper side and a lower side, which sides are parallel with each other and act as an alternating first support surface and second support surface. The milling insert is furthermore provided with major cutting edges, which are oriented perpendicularly to the axis of the mounting hole as well as arranged in such a way that a turning of the milling insert around the center of the mounting hole into an alternative cutting position alternatively a flipping of the milling insert into an alternative cutting position provides an identical position of the major cutting edges in relation to a workpiece. The major cutting edges of the milling insert are furthermore placed in the milling insert, when the same is tangentially mounted in a cutting body, so that the shortest distance of the major cutting edges to the axis of the hole in top view is smaller than the distance of a third support surface to the axis of the hole. A milling cutter tool having such a milling insert mounted is also disclosed.
