Abstract: A method is specified for producing a rotary tool (2) having a base body (4), which extends in a longitudinal direction (L) and in which at least one flute (6) is ground in by grinding in a first partial flute (12A) with a first helix angle (W1) in a first grinding step and by subsequently grinding in a second partial flute (12B) with a second helix angle (W2) in a second grinding step, the second helix angle differing from the first helix angle (W1) so that a flute (6) that expands in the longitudinal direction (L) is formed, wherein the two partial flutes (12A, 12B) are ground in using the same grinding wheel (11). In this way, a particularly quick production is realized. Furthermore, a corresponding rotary tool (2) is specified.

Abstract: The invention relates to a drill tip (2), comprising a center (4), at which a chisel edge (6) is arranged, and comprising a main cutting edge (8), which adjoins the chisel edge (6) and runs outward from the center (4). A rake angle is formed along the chisel edge (6) and the main cutting edge (8). The main cutting edge (8) has an inner portion (10), which adjoins the chisel edge (6) and is arranged within the center (4). The main cutting edge (8) has an outer portion (12), which outwardly adjoins the inner portion (10) and is arranged outside of the center (4). A point thinning (16) is formed on the drill tip (2), which point thinning is curved in such a way that the inner portion (10) runs arcuately from an outer edge of the center (4) toward the chisel edge (6). The invention further relates to a method for producing a drill tip (2) of this type.

Abstract: A rotary tool designed as a modular drill, extending in an axial direction along an axis of rotation. It comprises two coupling parts: a carrier; and a cutting head that is attached to the carrier so as to be exchangeable. The carrier includes pin receiving means, into which a coupling pin of the cutting head is introduced in a clamping manner and so as to be reversibly exchangeable. The pin receiving means and the coupling pin have torque sections and clamping sections that correspond to one another and are oriented parallel to the axis of rotation. In addition, to prevent axial pull-out, stop surfaces are provided on the pin receiving means and on the coupling pin, the stop surfaces being effective in an axial direction and corresponding to one another. These stop surfaces preferably extend horizontally and therefore perpendicular to the axis of rotation.

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: In one aspect, blanks for rotary tooling applications are described herein. Such blanks can employ architectures realizing material efficiencies and temporal efficiencies when processed into rotary cutting tools. For example, a rotary cutting tool blank described herein comprises a plurality of interior channels extending along a longitudinal axis of the blank, the interior channels having radial positioning for external exposure along an axial length of cut of the rotary cutting tool upon introduction flutes to the blank.
