A plate member of a cutting tool has two side surfaces being substantially rectangular in shape, a top surface and a bottom surface extending in a direction along a long side of the rectangle, and two end surfaces in a short-side direction. A cutting edge is located on the side of one of the end surfaces. One of the side surfaces is a curved surface bulging outward. The bottom surface has an inclined portion which is inclined with respect to the top surface. The plate member is held by a tool block having a bottom restraining surface which comes into contact with the bottom surface, and is fastened to the tool block by using a clamp member having a top restraining surface which comes into contact with the top surface of the plate member.

A cutting insert includes a body having three vertices, an upper face, a lower face, and six planar flank faces perpendicular to and joining the upper and lower faces. A cutting edge is formed at an intersection between the upper and lower faces and each of the planar flank faces. A triangular-shaped island surrounds a central axis, A, of the cutting insert and is higher in elevation than the upper and lower faces. A tool holder includes a tool holder body having a generally triangular-shaped insert-receiving pocket with a triangular-shaped recess that is substantially identical in shape to the triangular-shaped island of the cutting insert that interacts with the island to properly locate and prevent rotation of the cutting insert when mounted in the tool holder.

A cutting insert including a body having three vertices, an upper face, a lower face, and flank faces joining the upper and lower faces. At least one cutting edge is formed at an intersection between the upper face and the flank faces. A generally triangular-shaped island surrounds a central axis of the cutting insert and is higher in elevation than at least one portion of the upper face.

A cutting tool includes a two-way indexable cutting insert retained in a tool holder by a clamping member. The cutting insert has a tetrahedral basic shape and includes two cutting edges at opposite ends of thereof. The insert holder includes a forwardly located mounting portion that includes three spaced apart mounting jaws which together define an insert receiving pocket having a pocket opening. The clamping member is attached to the insert holder body so that a clamping portion of the clamping member protrudes into the pocket opening. When the cutting insert is releasably attached to the insert holder in a fastened position of a cutting tool, the cutting insert is located in the insert receiving pocket and clampingly engaged therein by the clamping portion.

A parting blade includes an internal cooling agent supply and has two substantially plane-parallel lateral faces and a continuous transversal bore connected to a cooling agent channel that runs parallel to the lateral faces in the interior of the parting blade. In order to provide a parting blade that has no projection on one side, a stopper is provided having two substantially parallel end faces and a circumferential face that connects the end faces. The stopper can be inserted into the transversal bore of the parting blade, thereby sealing the transversal bore relative to at least one lateral face of the parting blade. The stopper terminates without protruding over the sealed lateral face, flush with the lateral face. The stopper has an opening on both the end face and the circumferential face. The openings are connected to one another in the interior of the stopper to connect the cooling agent channel to a cooling agent source.

A tool assembly for heavy duty machining includes an insert, tool and clamp for securing the insert to a rigid insert seat of the tool. The insert is a solid cutting insert including a single cutting edge located at a corner region thereof. At a diagonally opposed corner region the insert is not subjected to clamping forces.

A groove insert to be received in a tool holder has, along its top and bottom side and on its rear side, a holding structure which is formed by holding faces which taper toward one another and by way of which the groove insert is fixed in the tool holder in a positive locking manner. The tool holder has corresponding counter faces. The groove insert and the tool holder form a groove cutting tool.

A tool for machining a workpiece is presented. The tool has a cutting insert with at least one cutting edge, a holder having a shank, and a cutting insert receptacle, wherein the cutting insert receptacle is arranged in a region of a workpiece-side end face of the shank, and the cutting insert is disposed in the cutting insert receptacle. The holder has a coolant bore, which opens out into a plurality of coolant outlets. The plurality of coolant outlets are arranged on the workpiece-side end face of the shank, alongside the cutting insert receptacle, and are oriented such that coolant is discharged towards the cutting insert. At least some of the coolant outlets lie in a coolant outlet plane which runs parallel to and offset from a cutting insert plane running through the cutting insert receptacle, where the coolant outlet plane and the cutting insert plane run parallel to the longitudinal direction of the shank.

A cutting tool holder has a holder body and a vibration damping weight assembly. The holder body has first and second side surfaces, and a top surface extending there between, and a cutting portion located at a front end of the holder body at the top surface thereof. A weight aperture opens out to the first and second side surfaces and has an aperture inner surface. A weight assembly is located within the weight aperture, having a first weight portion with a through hole, a second weight portion with a threaded hole, a damping ring located along the aperture inner surface, and a fastening member configured to connect together and urge the first and second weight portions towards one another, such that the contact surface of each weight portion presses against the damping ring, within the weight aperture.
