Abstract: A cutting tool (2)—in particular a rotary tool—is described, having a cutting edge (4) from which a rake face (6) and a clearance face (8) extend, characterized in that a groove (12) is introduced into the clearance face (8) in a region along the cutting edge (4) so that a part of the clearance face (8) is formed as a wear face (14) that extends between the groove (12) and the cutting edge (4) and is bounded by the groove (12) and the cutting edge (4). The groove (12) advantageously limits the wear of the cutting tool (2) in the region of the cutting edge (4) on the wear surface (14), so that overall the frictional forces that occur are kept small and the service life of the cutting tool (2) is extended. Furthermore, a cutting element for a cutting tool (2) as well as a method for manufacturing the cutting tool (2) are described.

Abstract: The rotary tool (2) is in particular designed as a modular drill and extends in an axial direction (4) along an axis of rotation (6). It comprises two coupling parts, namely a carrier (10) and a cutting head (12) that is attached to the carrier (10) so as to be exchangeable. A pin receiving means (20) is provided on the carrier (10), into which pin receiving means a coupling pin (40) of the cutting head (12) is introduced in a clamping manner and so as to be reversibly exchangeable. The pin receiving means (20) and the coupling pin (40) have torque sections (30a,b) and clamping sections (32a,b) that correspond to one another. In order to permit simple production, these clamping and torque sections are oriented parallel to the axis of rotation (6). In addition, in order to prevent pulling-out in an axial direction, stop surfaces (38a,b) are provided on the pin receiving means (20) and on the coupling pin (40), said stop surfaces being effective in an axial direction (4) and corresponding to one another. These stop surfaces preferably extend horizontally and therefore perpendicular to the axis of rotation (6).

Abstract: A method for producing a replaceable cutting head is described. The replaceable cutting head is manufactured by extruding a blank. During extrusion of the blank, a number of helical coolant channels and a number of helical flutes are simultaneously formed. After extrusion, the flutes have a first angle of twist (D1), and the coolant channels have a second angle of twist (D2). After extrusion, the blank is sintered and then reworked to selectively adjust the first angle of twist (D1) and the pitch of the flutes. The method produces an endless blank that is capable of being parted off to a desired length without any sacrificial allowance, which provides significant material and cost savings as compared to conventional methods.

Abstract: The invention relates to a method for producing a blank, in particular a blank for the production of a cutting tool, wherein a green body extending in the direction of the extrusion axis is produced from extrusion material by means of an extruder which has an extrusion channel extending along an extrusion axis; wherein the extrusion channel together with a movable mold element forms a die of the extruder; and wherein the mold element is moved relative to the extrusion channel and within said extrusion channel during the extrusion of the green body, whereby the shaping geometry of the die is changed so that the completely extruded green body hereby has a first functional segment and a second functional segment adjacent thereto in the direction of the extrusion axis (4); wherein the two functional segments differ with regard to their geometries impressed by the die.

Abstract: The mounting wrench (2) is used to engage or disengage a tool head (24) of a modular tool. The mounting wrench (2) incorporates a base body (4), which extends from an upper surface (20) along a centered longitudinal axis (18) to an underside (22). In addition, it has a slotted part (6), extending in the direction of the centered longitudinal axis (18), with a slot (10), into which the tool head (24) can be inserted. The slotted part (6) has two opposing keys (14), extending radially inward, which are each designed to mesh into a keyway (30) of the tool head (24). The keys (14) have a rounded end face (32), oriented radially inward, and are sloped relative to the centered longitudinal axis (18) so that the distance (a) between the keys (14) increases in the direction of the centered longitudinal axis (18).
