    摘要： A cutting tool has an insert holder with an indexable cutting insert removably secured therein. The cutting insert has upper and lower end surfaces with a peripheral side surface and a through bore extending therebetween, and a plurality of upper cutting edges formed on an upper peripheral edge. The peripheral side surface includes a non-circular upper relief surface adjacent the upper peripheral edge and a circular upper abutment surface spaced apart from the upper peripheral edge. Each upper cutting edge exhibits mirror symmetry about a bisector plane, and is non-linear in a side view. The through bore has an inner undercut formed by upper and lower bore surfaces located on opposite sides of a median plane, and a clamping member makes contact with one of the upper and lower bore surfaces at an inner contact zone located between the median plane and a seat surface of the insert holder.

    摘要： The invention relates to an indexable insert for solid drills comprising four identical cutting edges (30) arranged at a distance above a supporting base (42) and each extending between two cutting-edge corners (28', 28'). The cutting edges are each bounded by a cutting face (46) and a clearance face (48), with the inclusion of a wedge angle (b). Of the cutting edges (30), one in each case is in an active operating position during the drilling operation. To permit optimum adaptation to the cutting conditions and drilling characteristics, varying over the length of the cutting edge of the drilling tool, it is proposed according to the invention that the height (h) of the four cutting edges (30), measured from the plane of the supporting base (42), and/or the clearance angle (a) varies over the length of the respective cutting edges (30).

    摘要： The invention concerns a tool for machining workpieces, in particular a cutting insert, having a plurality of groove-like and/or raised machining elements which are disposed along the cutting edge (11) and adjacent one another in a row. The machining elements also have an elongate extension with a longitudinal axis defined thereby. At least in the vicinity of the cutting edge, the machining surface has a microstructure in the form of imbricated scales, the individual scales (12, 23 to 25) being arranged immediately adjacent one another. According to the invention, the scales (12, 23 to 25) comprise comb-like, curved apex lines (121) which form an angle (nue) of between 55° and -5° towards the cutting edge (11) with the cutting edge normals to the machining surface. The scales (12, 23 to 25) each have a cross-section which is parallel to the cutting edge and which has a steeper flank (122) and a flatter flank (123), each flatter flank (123) lying on the side facing the centre of curvature. The invention further concerns a boring tool equipped with said cutting inserts.

    摘要： A cutting insert for use in a cutting tool has upper (2), lower (3) and side surfaces (4) and at least one cutting edge (10) formed at an intersection of the upper surface with the side surface thereof. A rake face (13) of the insert is formed with an undulated chip forming groove (15) extending along the cutting edge (10) and comprising a succession of alternating depressed (20) and raised portions (21). Each portion of the chip forming groove (15) is formed with a truncated top portion (22) of a width which is substantially less than a distance between two adjacent truncated top portions. The depressed (20) and raised portions (21) preferably extend in the direction perpendicular to the cutting edge (10), along the entire width of the chip forming groove.
