    摘要： A replaceable cutting head includes a forward cutting portion and a rearward mounting portion. The mounting portion includes a male coupling member that protrudes rearwardly from a base surface. The male coupling member includes three circumferentially spaced apart head fixation members, where each head fixation member has a head peripheral surface that spirals inwardly in a direction against the direction of rotation and diverges. A tool holder includes a female coupling member extends rearwardly from a holder forward surface. The female coupling member includes three circumferentially spaced apart holder fixation members, where each holder fixation member has a holder peripheral surface that diverges rearwardly. When a cutting tool, which includes said cutting head and tool holder, is in a locked position, the male coupling member of the replaceable cutting head is removably retained within the female coupling member of the tool holder by means of a self-lock mechanism.

    摘要： A milling tool has a tool shank and a cutting head fastened to the forward end of the tool shank by way of a clamping connection. The clamping connection has a protrusion with clamping faces, and a recess with centering faces that interact with the clamping faces. Each of the centering faces has a first region where the centering faces are spaced from a longitudinal axis of the tool shank by a first distance and a second region at a smaller distance. The first region merges into the second region. The clamping faces of the protrusion are introducible into the recess between the first regions of the centering faces and are movable, by rotation of the cutting head about the longitudinal axis, into a clamping position in which the clamping faces interact in a force-fit with the second regions of the centering faces.

    摘要： A rotary cutting tool includes a replaceable cutting tip having a cutting portion structured to perform cutting operations on a workpiece and a first threaded portion disposed generally opposite the cutting portion. The cutting tool further includes a generally cylindrical tool body disposed about a central longitudinal axis. The tool body has a first end portion adapted to be coupled to a machine tool and an opposite second end portion having a second threaded portion cooperatively engaged to the first threaded portion. The second threaded portion is moveable with respect to the tool body in a manner that selectively couples the cutting tip to the tool body.

    摘要： A modular cutting tool holder portion for a metal-working machine includes a first engagement face configured for clamping engagement with a corresponding second engagement face of a complementary modular cutting tool holder portion. The first engagement face includes a base surface and interlocking elements in the form of exactly four projecting protrusions or exactly four recesses. Each interlocking element includes a non-contact surface spaced from the base surface. The non-contact surface includes two opposing edges between which it extends, and two abutment surfaces each extending from a respective one of the two opposing edges to the base surface and being configured for the clamping engagement.

    摘要： A tool holder includes a body, a cutting head having a cutting end portion and a tapered end portion, a retention knob located at the tapered end portion of the cutting head, and a ball clamping mechanism received in an aperture of the body. The ball clamping mechanism includes an upper clamp, a lower clamp, and a double-ended clamp screw threaded onto the upper and lower clamps. Rotation of the clamp screw in a one direction causes the upper clamp and the lower clamp to move toward each other and engage the retention knob to place the tool holder in a locked position, and rotation of the clamp screw in an opposite direction causes the upper clamp and the lower clamp to move away from each other such that the upper and lower clamps no longer engage the retention knob to place the tool holder in a unlocked position.
