  • Publication number: 20250229344
    Abstract: Drill bit including a drilling shaft and a cutting portion having a first drilling segment, a second drilling segment and a third drilling segment. The first drilling segment has a first inner lateral surface with a first inner distance, the second drilling segment has a second inner lateral surface with a second inner distance, and the third drilling segment has a third inner lateral surface with a third inner distance from the longitudinal axis of the drilling shaft. The first inner distance varies between a first maximum value and a first minimum value over the circumference of the first drilling segment and has precisely one first absolute minimum value. The second inner distance is greater than or equal to the first absolute minimum value over the circumference of the second drilling segment, and the third inner distance is greater than or equal to the first absolute minimum value over the circumference of the third drilling segment.

  • Publication number: 20240416433
    Abstract: Drill bit (20) including a drilling shaft and a cutting portion having a first drilling segment (23-1) and a second drilling segment (23-2). The first drilling segment (23-1) has a first inner lateral surface (28-1) with a first inner distance (B1(?), h)), and the second drilling segment (23-2) has a second inner lateral surface (28-2) with a second inner distance (B2(?, h)) from the longitudinal axis (24) of the drilling shaft. The first inner lateral surface (28-1) is formed as a portion of a first inner cone (34-1) which tapers in the direction of a first upper side (32-1) opposite to the underside (31-1) of the first drilling segment (23-1).

  • Patent number: 12030121
    Abstract: A method for producing a machining segment for a machining tool, where the machining segment is connectable to a basic body of the machining tool by an underside of the machining segment, includes producing a green body by placing first hard material particles in a matrix material in a defined particle pattern, where the first hard material particles are placed in the matrix material with a respective projection with respect to the matrix material. The green body is compacted by pressure between a first press punch, which forms the underside, and a second press punch, which forms an upper side of the machining segment, to form a compact body, where the upper side is opposite from the underside. The compact body is processed by temperature or by infiltration to produce the machining segment.

  • Publication number: 20220055184
    Abstract: A machining segment for a machining tool which is rotatable in a direction of rotation about an axis of rotation includes an underside where the machining segment is connectable to a basic body of the machining tool by the underside. The machining segment has a machining zone of a matrix material and a plurality of first hard material particles that are disposed in the matrix material in accordance with a defined particle pattern. An upper side of the machining segment, opposite from the underside, is divided into a plurality of machining regions, which include respective ones of the plurality of first hard material particles, and a plurality of matrix regions which are built up from the matrix material. At least one of the plurality of machining regions has with respect to an adjacent matrix region a projection that is greater than 400 ?m.
