Cutting Tool, E.g., Drill Bit, Etc. Patents (Class D15/139)
  • Patent number: 12330220
    Abstract: The invention relates to a cutting tool for machining, in particular for a peeling-like machining process, comprising a chip-forming depression which runs along the cutting edge and in which elevated chip-forming elements are formed. According to the invention, the elevated chip-forming elements have an elongated contour with a length which is greater than the width, in plan view, such that the chip-forming elements have a rising flank and a falling flank. The rising flank, which is longer by comparison, is defined by a rising angle (?) of 3° to 20°, preferably 5° to 10°, and a falling angle (?) of 25° to 45°, preferably 27° to 35°, and the transition between the rising flank and the falling flank is rounded, the radius (R) of said rounded section ranging between 0.05 mm and 1 mm, preferably between 0.25 mm and 0.4 mm.

  • Patent number: 12251766
    Abstract: A cutting insert includes a first and a second pair of opposing side surfaces. As seen towards a first side surface, a first axial relief face and a first axial abutment face form part of a first surface grouping on a first side of a longitudinal plane. As seen towards a second side surface, a second axial relief face and a second axial abutment face form part of a second surface grouping on the first side of the longitudinal plane. The first axial abutment face forms a substantially flat surface and extends perpendicularly to a median plane of the insert. The second axial abutment face forms a substantially flat surface and extends perpendicularly to the median plane. A second side surface of the first pair of opposing side surfaces has a first and a second radial abutment face.
