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.

An insert may include a main body. The main body may include a first surface, a second surface, a side surface, a first cutting edge and a through hole. The side surface may be located between the first surface and the second surface. The first cutting edge may be located on at least a part of a ridge line where a first side surface of the side surface intersects with a second side surface adjacent to the first side surface. The through hole may open into the first surface. The main body may further include a first concave part located from the first surface to the side surface. The first concave part may be located away from an imaginary straight line connecting the first cutting edge and a center of the through hole in a front view of the first surface.

A tool system for machining a workpiece is provided having a cylinder-shaped retaining shank that has a cutting head holder on an end surface facing the workpiece, a drive mount on an end surface facing the drive, a cutting head having at least one cutting edge, a cutting head hub corresponding to the cutting head holder on the retaining shank, a tool coupling with a tool interface, and a coupling hub corresponding to the drive mount. The coupling hub or the cutting head hub have elevated areas, with contact surfaces, distributed in circumferential and longitudinal directions of the coupling hub or the cutting head hub. The contact surfaces make contact on support surfaces on the drive mount or on the cutting head holder on the retaining shank. The drive mount or the cutting head holder is permanently connected to the coupling hub or the cutting head hub by a joining material in intermediate spaces between the elevations.

Provided is a cutting tool that implements both high positioning accuracy and simple operation when the cutting tool is installed in a tool rest. The cutting has: a tool a main body which includes a fixing seat fixing a cutting insert or a cutting edge; and a position pin, which includes a cylindrical portion that is used for positioning the main body by being abutted to an abutting surface of a tool rest in a case of installing the main body in the tool rest, and which is detachable from the main body. The main body includes a female screw hole that is provided with a female screw portion and a tapered surface that is symmetric with respect to a center axis of the female screw portion and that widens toward an opening thereof. The positioning pin includes a male screw portion that engages with the female screw portion, and a contact portion located at a connecting portion that connects an end of the cylindrical portion and an end of the male screw portion. In a case where the male screw portion is engaged with the female screw portion and the positioning pin is installed in the main body, the contact portion contacts the tapered surface, and a center axis of the cylindrical portion and a center axis of the tapered portion match with each other.

Tool system 1 comprising a tool holder 2 that has an insert seat 17 for receiving a cutting insert 6, and comprising a clamping element 4 that has an opening 26 for receiving a clamping means 15, an interface 30 being arranged between the tool holder 2 and the clamping element 4, and channels for the purpose of cooling by means of a fluid being arranged in the tool holder 2 and the clamping element 4, and a sealing means 31 being arranged in the region of the interface 30.

A blade positioning structure of a disposable milling cutter includes a cutter body and a disposable blade. The cutter body is peripherally provided with a blade seat. By passing a screw through the disposable blade and the blade seat, the disposable blade is locked to the blade seat. The blade seat has a blade seat surface and a sidewall; the blade seat surface has a groove; the disposable blade has a bottom surface provided with a projection corresponding in shape to the groove; and when the disposable blade is locked to the blade seat, the blade seat surface and the groove of the latter lie respectively and tightly against the bottom surface and the projection of the former.

A holder for a cutting tool for processing of workpieces has a first part for holding a cutting tool (150), a second part (120) to which the first part is fastened, and a fastening element (140). An adjustment element adjusts the position of the first part in relation to the second part. The first and second parts have a first bore and a second bore for receiving the fastening element and a recess (118, 128) for receiving the adjustment element. The first part has an abutment surface (115) placed onto a contact surface (122) of the second part, such that the central axes (A-A) for the first and second bores become parallel. The abutment surface of the first part and the contact surface of the second part are inclined in relation to the feeding axis (G-G) of the work piece towards the cutting tool (150).

A cutting tool including an insert and a holder to which the insert is secured. The insert has a rod with a substantially circular transverse cross-section. The insert includes a shank portion and a cutting edge portion. The cutting edge portion is located at an end portion continuous with the shank portion. In the cutting edge portion, one end of a cutting edge ridge protrudes toward the periphery of the rod. When the insert is secured to the holder, the cutting edge ridge has a negative radial rake angle.
