  • Patent number: 7641423
    Abstract: A device for chip removing machining includes first and second parts coupled together, wherein one of the parts includes a cutting edge. A coupling between the first and second parts includes two interacting surfaces and a clamp for forcing the surfaces together. The surfaces are profiled with male and female members, respectively, that are intercoupled to establish a form locking of the first and second parts against each other. The first and second parts are provided with central holes for receiving the clamp. The male and female members are configured to define only a single position of intercoupling.

  • Patent number: 7478978
    Abstract: The present invention relates to a tool head preferably for milling. The tool head is connectable to a toolholder. The tool head includes a cutting portion and a mounting portion. The mounting portion includes an axial stop surface and a radial stop surface. Dimensions and tolerances of the axial stop surface and the radial stop surface are selected such that the axial stop surface will abut an axial stop on the toolholder to prevent axial movement of the toolholder relative to the tool head beyond the axial stop surface and the radial stop surface will be disposed proximate a radial stop of the toolholder to limit radial movement of the tool head relative to the toolholder when an integral fastening portion of the tool head and an integral fastening portion of the toolholder are fastened directly to one another and the axial stop surface and the axial stop abut.

  • Patent number: 7374376
    Abstract: The present invention relates to a replaceable cutting tip and, more particularly, to such cutting tips attachable to the cutting tip holders by a threaded connection. The cutting tip for a cutting tool includes a working end portion disposed along an axis of the cutting tip and including one or more cutting edges for machining a workpiece, and a mounting portion disposed along the axis of the cutting tip. The mounting portion includes a frustoconical supporting surface tip portion and a frustoconical threaded portion. The present invention also relates to a cutting tool per se.

  • Patent number: 7341409
    Abstract: The present invention relates to a tool and a male part for chip removing machining. The tool includes a male part and a holder for the male part. The male part includes a radial and axial supporting and positioning portion and a threaded portion. A largest diameter of the externally threaded portion is smaller than a smallest diameter of the radially and axially supporting and positioning portion. A transition portion is disposed along the axis of the male part between a radially largest portion of the radially and axially supporting and positioning portion and the externally threaded portion.

  • Patent number: 7001114
    Abstract: An apparatus for chip removing machining includes first and second parts which are intercoupled by a coupling. The coupling includes two interacting surfaces disposed on the first and second parts, respectively. The interacting surfaces are profiled to intermesh with one another to define an intermeshing region of the coupling. Each of the surfaces is profiled with first and second sets of grooves which define first and second main directions, respectively, which extend transversely to one another. At least one groove on each of the surfaces extends across less than the entire intermeshing region, wherein the surfaces define only one coupling position for the first and second parts.
