    Abstract: An indexable tangential cutting insert for a milling tool includes two opposing side surfaces and four identical lateral surfaces extending between the side surfaces. Each lateral surface of the insert is provided with a support surface configured to be supported by, on one hand, a corresponding support face of a pocket of a tool body providing an axial support to the insert in two of eight index positions and, on the other, a corresponding support face of the pocket providing a tangential support to the insert in two other of said eight index positions. Each lateral surface of the insert is provided with a single second support surface being concave as seen in a direction perpendicular to said side surfaces and extending diagonally across the lateral surface.

    Abstract: The present invention relates to a powder mixture for three-dimensional (3D) printing of a cermet or a cemented carbide body. The powder mixture includes 65-85 wt % of porous cemented carbide or cermet particles of a median particle size (D50) of 10-35 μm, and 15-35 wt % of a dense cemented carbide or cermet particles of a median particle size (D50) of 3-10 μm. The present invention also relates to a method of making a cermet or cemented carbide body, the method including the steps of forming the powder mixture, 3D printing a body using the powder mixture and a printing binder and thereby forming a 3D printed cermet or cemented carbide green body and sintering the green body and to form a cermet or cemented carbide body.

    Abstract: A tool body and a turning tool for grooving operations having the tool body include a fitting member extending along a longitudinal first axis for fixing the tool body to a machine. The tool body's upper and lower clamping members each having respective inner seating surfaces facing one another and separated by an intermediate gap in which a cutting insert is insertable. A major part of the lower inner seating surface extends along a second axis perpendicular to the first axis. The clamping members are movable toward one another by a tightening device in order to secure the cutting insert in the intermediate gap. The tool body is integrally formed in a unitary piece. A hinge joint is formed between the clamping members, such that they are movable with respect to one another by turning around an axis of rotation of the hinge joint, extending perpendicularly to the second axis.

    Abstract: A crusher wear resistant liner for positioning at a crusher bottom shell includes a plurality of modular wear resistant plates mountable at an inside surface of the bottom shell and positioned side-by-side to surround and protect the bottom shell interior. To prevent independent dislodgement of each plate and liner, respective inter-engaging formations are provided at each plate to contact at least one adjacent plate of the assembly to arrest any unintentional downward movement in the event that the primary fixings become ineffective.

    Abstract: A metal cutting tool holder includes a tool holder body having a first fluid passage extending in a first direction between a first inlet and a first outlet, and a second fluid passage extending in a different second direction between a second inlet and a second outlet. The tool holder body has a cavity and the first outlet and the second inlet intersect the cavity. A member is positionable in the cavity such that a curved third fluid passage connecting the first outlet and the second inlet is formed at least partially by the member. The curved third fluid passage extends from a first end adjacent to the first outlet to a second end adjacent to the second inlet. The first direction is tangent to the curved third fluid passage at the first end, and the second direction is tangent to the curved third fluid passage at the second end.
