Abstract: The invention relates to a drill head comprising at least one surface, with a number of structural elements, wherein the structural elements are manufactured by an additive or primary forming manufacturing method. The invention further relates to a method for manufacturing such a drill head.

Abstract: The invention relates to a method for producing a coated body, with a substrate and a coating arranged on the substrate, which coating comprises at least one base layer applied to the substrate and at least one metal carbide-containing layer arranged over the base layer, which layers are applied by means of magnetron sputtering. Furthermore, the invention relates to a coated body produced according to the method.

Abstract: A system and method for monitoring and predicting wear of a cutting tool used for machining a workpiece is disclosed. The system includes a cutting tool having a shank and a cutting head. The system also includes a split, modular and wireless wear detection system including one or more sensors mounted to the cutting tool for providing a data signal representative of a physical condition of the system, and a data recording and data transmitting device for recording the data signal from the one or more sensors and for generating and transmitting a data signal to a processor. The processor applies a machine learning data processing technique in real time to monitor and/or predict a condition of various components and/or parameters of the system during a metal cutting operation.

Abstract: The invention relates to a rotary tool (2), comprising: a main blade (4), a chip flute (6), a lateral surface (8), and a flank (10) trailing after the main blade (4), wherein the flank (10) first drops off proceeding from the main blade (4) and then rises again, such that a sink (12) is formed, to which a ridge (14) adjoins, which reaches up to the lateral surface (8) and the chip flute (6). The invention further relates to a method for manufacturing a rotary tool (2).

Abstract: A modular cutting tool includes a base body, an intermediate body removably attached to the base body, and a cutting head at least partially disposed within a pocket of the intermediate body. A tooling tree allows a user to select a different combination of the base body, the intermediate body and the cutting head of the cutting tool based on desired physical properties of each component.

Abstract: A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.

Abstract: A rotary cutting tool (10) has an axis of rotation (R) and a tool body (12) extending along the axis of rotation (R) and having at least one coolant channel (30). At least a portion (32) of the at least one coolant channel (30) is formed by a groove (40) in a circumferential face (42) of the tool body (12). Furthermore, the at least one coolant channel (30) in the portion (32) of the groove (40) is closed in the radial direction by an add-on part of the rotary cutting tool (10) attached to the tool body (12). Furthermore, a method for manufacturing such a rotary cutting tool (10) is provided.

Abstract: A modular drill including a shank having a shank bore therein, a guide pin tip disposed in the shank bore, a cutting tip, and a connection shaft coupled to the cutting tip, the connection shaft having a connection shaft sidewall and a guide path therein for guiding the guide pin tip therethrough while the connection shaft moves through the shank bore.

Abstract: The invention describes a rotary cutting tool, in particular a drill, which comprises a first cutting tool part having at least one cutting edge and a second cutting tool part which comprises a cutting tool shank. The first cutting tool part and the second cutting tool part are releasably connected to one another via a coupling mechanism which comprises a coupling cam that is mounted on one of the two cutting tool parts such that it can rotate about an axis of rotation and, in a coupling position, abuts an engagement surface on the other cutting tool part. The invention also presents a cutting tool part, in particular a cutting tool base, and a further cutting tool part, in particular a cutting tip.
