A cutting tool according to one aspect of the present disclosure includes a substrate and a diamond layer coating the substrate. A cutting tool according to one aspect of the present disclosure includes a rake face, a flank contiguous to the rake face, and a cutting edge configured by a ridge formed by the rake face and the flank. The rake face has a first rake face and a second rake face located between the first rake face and the flank. The second rake face and a surface of the substrate located on the side of the rake face form a negative angle. The second rake face is formed at the diamond layer.

A method for the laser-based generation of a structure on a rake face of a cutting tool is disclosed, where at least one structure is formed by lines that are generated with a mutual spacing of at most 400 m with a laser beam at least in areas within a predetermined contour on at least one rake face of the cutting tool. A course of the lines forming the structure is oriented with respect to a profile of at least one cutting edge of the at least one rake face.

A cutting insert has an upper surface (21), a lower surface (91) and a side surface (61) that connects the two surfaces. A cutting edge is formed at an intersecting edge between the upper surface (21) and the side surface (61). The cutting edge includes at least a major cutting edge (33), a corner edge (34) connected to the major cutting edge (33), and a curved wiper edge (35) located on the opposite side of the major cutting edge (33) across the corner edge (34). A first angle made by the major cutting edge (33) and the chord of the wiper edge (35) is 155<180, and a positive land is formed in the wiper edge (35). The cutting edge may further include an inner cutting edge (36) located on an opposite side of the corner edge (34) across the wiper edge (35).

A method for the production of a reamer, such as a burr for milling a patient's acetabular cavity, including a substantially hemispherical, hollow cutting body with a perforated wall. The method includes a step of forming at least one tooth by stamping the wall, during which an area of the thinned portion of the wall, adjacent to a hole, is pressed between a punch and an anvil.
