摘要： A cutting tool includes a tool holding system having a clamping portion. The clamping portion includes an integrally formed one-piece inner coupling member that at least partially forms a clamping sleeve portion having a clamping bore for clampingly receiving a cutting insert. The clamping portion also includes an integrally formed one-piece outer coupling member that is circumferentially disposed about at least a portion of the inner coupling member. The tool holding system also has a mounting portion that is connected to one of the inner and outer coupling members. The inner and outer coupling members are captively and non-releasably engaged with each other via inter-engaged first and second engagement surfaces that are slidingly displaceable with respect to each other.

摘要： A swiss turning tool assembly includes an insert and a tool holder. The tool holder includes a head portion which in turn includes an insert pocket and a fastener hole opening out to a flank side of the tool and to a pocket opening in the insert pocket. The insert pocket also includes a tool clamping arrangement which in turn includes a tool base surface and at least one tool abutment surface forming an external acute angle with the tool base surface. The insert includes an insert base surface which in turn includes at least one insert abutment surface forming an internal acute angle with the insert base surface. To achieve a clamped position, a single fastener, accessed from the tool's flank side abuts the insert.
